Welcome to Misumi's new
19-minute webinar series. For those of you here that are new to Misumi,
Misumi is a global supplier of configurable components.
Hi, my name is Shawn Hennessey from the Engineering Department
at Misumi USA. In this webinar
I will be talking about in detail our lineup of
linear shaft supports. Misumi's most popular product is our
configurable linear shafts. However, Misumi also offers a wide range of supporting
accessories for the shaft.
One of the key supporting products are the shaft supports
used to hold the linear shafts in place. Every application is different
so it can be very difficult to find the right shaft support
to fit the surroundings. That's why Misumi offers over 50 different shapes and
styles.
With this wide range of shaft support selections
Misumi can cater to the most space constraints
encountered during design. The two main categories
of shaft supports are the flange type and block type. We will review both options
of these categories and discuss some of the features and benefits of each.
These housings are available in cast or machined
based on the type of housing selected. Housings offered in precision cast
are offered at a lower price than the machine products but have a slight d molding
draft and gritty surface.
However, the dimensions are precisely finished
as shown in the catalog. Let's start by taking
a look at our flanged housings. Misumi has many variations
of flanged shaft supports as seen in these slides of options.
The flanged type shaft support are offered with different mounting options.
The through hole flange type can be installed to a mounting plate
using the four through holes on the face the flange. The dowel hole flange type
includes to H7 holes which can be used to achieve precise positioning.
Dowel pins can be inserted with ease and helps improve assembly time.
The pilot flange type offers similar benefits
when an application has a pilot hole. This shaft support design
allows for easy positioning during assembly and easy repeatability
for replacement and maintenance. The final mounting option offered is the
tapped hole
flange type. For this part type the mounting holes
are threaded and are best used when mounting plate are thin
or may have insufficient strength such as aluminum.
The standard mount flange support is one of our most popular designs
and has several material options that are highlighted in blue. It is offered
with round,
square, and compact flange shapes. The standard mount types
use set screws to secure the shaft. Several variations
of the standard mount are offered including long sleeve type,
which increases the length of support sleeve and enhances the rigidity of the
assembly.
Another variation is the pilot flange
where a support sleeve extends on the backside of the flange.
It can be inserted into a hole in the mounting plate
to reduce the length of the protruding section and helps better locate the
support unit.
Two of the standard supports are offered with alternative mounting methods.
The first option changes the standard through mounting holes
to tapped mounting holes. The second option adds dowel holes on the flange.
Misumi also offers inch size shafts supports for the flange types
outlined in red. The material options for the inch sizes
are the same except for the aluminum option which uses a different grade.
The standard mount thick sleeve supports are very similar to the standard mount
part type in design. The main difference is the increased sleeve thickness
which provides improved rigidity. The material and surface treatment options
are identical
except this part type is offered with 5056 aluminum
instead of 6061 aluminum. Like the standard mount
the thick sleeved part type is offered with long sleeves,
pilot flanges, and dowel holes for the noted options.
The next group of flanged shaft supports is the slit sleeve type.
The supports have a machine slit and tapped hole
which are used for clamping. These features allow a shaft to be easily and
securely fastened.
Like the previous flange types, the slit sleeve supports are offered with
long sleeves, pilot flanges,
and dowel holes for the noted options. These supports are offered with carbon and
stainless steel material options.
The compact shaft supports have mounting holes located on the face of the support.
This feature is beneficial in space-saving designs.
The product is offered in carbon steel and stainless steel.
The keyway shaft supports are modeled after our standard flanged supports.
The machined keyways help prevent a shaft from rotating in the sleeve.
Our keyway supports are offered in 1045 carbon steel.
The back mount type offers a unique shaft securing method.
By using a shaft is tapped on one end and a hexagon socket head cap screw
a designer can firmly fix the shaft to the support.
The split housing shaft support has a sleeve that is split into two parts.
The removable parts of the sleeve allows for easy shaft removal
during installation and maintenance.
The material choices for the shaft supports include steel
and stainless steel.
The final flange type is the precision cast shaft support.
The Precision Cast parts have a slip machined into the sleeve
that allows a shaft to be clamped tightly.
It is one of our most economical shaft supports.
The long sleeve variation of this part provides improved
shaft gripping power.
Misumi also offers the standard precision cast shaft supports in inch sizes.
Both inch and metric sizes are offered in carbon steel,
stainless steel, and aluminum. Next
we'll be looking at Misumi's block type shaft supports.
Misumi has many variations of block shaft supports as seen in this slide of
options. The block type shaft supports are offered with different shaft securing
methods.
The set screw type has a tapped hole that is perpendicular to the inner bore of
the shaft support. By inserting a set screw into this tapped hole,
a shaft with a flat machined onto a surface can be locked into place.
The split type has a removable section that allows for easy maintenance.
This part type uses multiple hexagon socket head cap screws
to clamp a linear shaft into place.
The slit inside slit types have a slot machined
into the top inside of the inner bore respectively.
A linear shaft can be effectively secured inside the bore without damaging the
surface.
The hinge type is similar to the split type since the hinge insures
easy installation a maintenance. However,
it also enables enhanced working efficiency because only one tightening
screw is required.
The t-shaped shaft supports is one of Misumi's most popular block types
and is offered with six variations; set screw,
wide, hinge, slit,
side slit, and split. The standard and slit
types are also offered with dowel holes for quick accurate positioning during
installation.
Misumi also offers inch size shaft supports
for the block types outlined in red.
Both the metric and inch t-shape supports are offered with aluminum, steel,
and stainless steel material options.
The t-shaped shaft supports are also offer with clamp levers.
The clamp lever type is advantageous when frequent shaft position adjustments
are required. The lever also allows for easy maintenance.
Misumi also offers precision cast t-shape mounts made of carbon steel,
stainless steel, and aluminum. The precision cast
is an inexpensive alternative to the machined t-shape supports.
Five precision cast variations are offered: set screw,
slit, side slit, wide,
and split. The L-shaped shaft support is useful when cross-wise space is limited.
The L-shaped mount has five different variations:
set screw, hinge, side slit,
split, and slit.
Misumi also offers inch L-shape supports for the side slit,
split, and slit types.
The material options include carbon steel, stainless steel,
and aluminum for metric and inch options.
The precision cast L-shape supports are a low-cost alternative to the machined
L-shape supports. The precision cast supports have a slight demolding
draft and gritty service but the dimensions are precisely finished.
Four precision cast variations are offered: set screw,
slit, side slit, and split.
The material options are carbon steel and stainless steel.
The compact shaft support is effective for space-saving designs
and it is the smallest shaft support offer by Misumi.
The compact type is offered with four different designs: set screw,
wide, side slit, and split.
The split type support is also available with dowel holes.
The material options for the compact shaft supports are carbon steel
and stainless steel. The bottom mount support is suitable for designs
where lengthwise and crosswise space is limited. This shaft support has tapped
holes located
on its base and can be screw mounted. This is particularly effective
when a mounted plate is too thin to tap. There are six versions of the bottom mount:
set screw, wide, hinge,
side slit, split, and slit.
The material options include carbon steel, stainless steel, and aluminum.
The side mount support, like the bottom mount, is useful when crosswise
and lengthwise space is limited. The two clearance holes located on the face of the
support
allow for side mounting on adapter plates. The side mount has five different
variations:
set screw, hinge, slit, side slit,
and split types. The material options include carbon steel, stainless steel,
and aluminum. Misumi's flange type shaft supports can be selected with nominal
bore sizes ranging from three to 50 millimetres
and 0.125 to 1.5 inches.
The bore diameter of the shaft support will match the nominal diameter of the linear
shaft
when these components are used together. The tolerance for the majority of our metric
shaft supports
is h7. The tolerance for our inch shaft supports
are also oversize and the tolerance range is depending upon the bore size.
These shaft supports with oversized bores are used under with undersized shafts
which results in a clearance fit. This clearance fit allows the shaft to be
cleanly inserted
into the shaft support while reducing instances of marring etching along its
surface.
For our split and slit type shaft supports the tolerance
is marginally different. Split type shaft supports have a tolerance
of zero to plus point one millimeters
for all bore sizes. For the slit type,
the machining on the slit can change the tolerance to H8
or slightly higher. However, this slight tolerance change will not affect the
functionality of this part.
The combined use of Misumi shafts with standard g6,
f8, or h5 tolerances and Misumi
shaft supports are recommended. For Misumi shaft supports
there's one alteration. The MB alteration includes
hexagon socket set screws with the shaft support.
These set screws can be used to secure the shaft inside the support.
The size and material of the set screws will be dependent upon the shaft
support material and size.
For our machined block type shaft supports Misumi offers selectable
and configurable based center height.
This dimension is represented by the H callout.
This adjustable height can help reduce design constraints
and provides opportunities for assembly optimization.
For our L and T shape supports the H dimension is both selectable and configurable
in 0.1 millimeter increments.
For the other block type supports the H dimension is only selectable.
What is configurable? Let's visit Misumi's website
and show an example of a configured shaft support.
This is Musumi's is globally recognized homepage. Misumi is divided into three
divisions:
Automation Components, Press Die Components, and Plastic Mold Components.
We will be focusing on Automation Components for this webinar
so I will select the Automation Components icon.
The Automation Components homepage showcases our major product categories
on the left hand side and sub-categories in pictorial index on the right.
For this session we'll be focusing on the shaft supports.
From here you can narrow down your search by either filtering down on the
left hand side
or scrolling through the descriptions for your exact match.
You can also click on the enlarge button to see a larger picture of each product
or details for a side by side technical comparison.
For this example I will select ten millimeters from my hole diameter
on the filter column. For my support type
I will choose L-shaped. Next I will select
set screw for the shaft fastening type.
Lastly, I will select stainless steel for my material.
Now you can see that I only have one option to select.
By selecting this option the site will take me to the part detail page where I
can make the final specification
for my shaft support.
On the part detail page, also known as the configurator,
you'll see the default drawing view with blue dimensions
These blue dimensions can be specified by a designer.
Since I've already selected a bore diameter, only one more dimension needs to
be specified,
The base to center height represented by the H call-out.
Since the L-shaped has selectable and configurable options,
you can select this dimension in two places.
The selectable options are shown in the drop down box.
If you cannot find the size you require you can specify a configurable height
in 0.1 millimeter increments in the text box located
below the drop down box. For this example I will select a configurable height of
36.6 millimeters.
After completing all the sections you'll get a part number that is globally
recognized.
We can now click on the Price Check icon to find the price and delivery information
for this part.
Our standard one piece price for the shaft configuration
is $112.25 and there is no
minimum order size.
As for the delivery the shaft support will ship from our warehouse in eight
business days or less.
Now that you understand Misumi's configurable business model
you can see how standardizing simple machine products can save you time and
money.
Detailed drawings are not required, no CAD drawing administration,
especially for replacement parts and revisions.
Misumi is making configurable the new standard.
Now I'll review some customer submitted industry examples
using Misumi linear shaft supports.
The first design is for material testing. A combination of linear shafts,
shaft supports, and other components are used to create a fatigue tester.
This design uses two T-shape slit supports
to clamp the linear shafts into place using hexagon socket head cap screws.
The support is mounted on an adapter plate along with a lead screw support
unit.
To ensure that the linear shaft lined up with the lead screw
the designer used the configurable shaft support and specified the exact
base to center height to ensure an optimal design.
This for example, is a wire guide used in the electronics industry.
This design utilizes several different shaft support types
including t-shape split supports.
The complex split shaft support
and the standard mount compact flange support.
For this design, the t-shape split support is used when precise base to center height is
required
and to ensure easy repeatability during maintenance.
The compact split support is required when space is an issue
and similar to the t-shaped split support when frequent maintenance is required.
The standard mount compact flange is necessary for vertical applications with
limited clearance.
Our last example shows a simple linear actuator assembly that is completely made up
of Misumi components.
We showcased our shaft supports in this presentation, but Misumi offers a wide
range of complementary products
such as linear shafts, bushings,
collars, and many other components to complete your automation assembly needs.
