Why does the locking screw always slip when locking the guide shaft?

Due to the wall thickness, the shaft support usually has only 2 to 3 effective teeth. If the torque is too large or inclined fastening is performed, it is easy to cause slippage.

What is the verticality between the mounting surface of MISUMI shaft support and the inner hole?

The verticality between the mounting surface and the inner hole is less than 0.02.

What is the surface treatment of MISUMI shaft support? What is the anti-rust performance?

Surface treatment of black oxide and electroless nickel plating is available, and electroless nickel plating has better anti-rust performance.

When fastening the guide shaft with the shaft support, how can the guide shaft be fastened without damaging the guide shaft?

Locking screws with brass or urethane heads can be used for fastening to reduce damage to the guide shaft.

Product Overview

The shaft support can support and fix the shaft and also bear a certain load.

Product Feature

Feature 1: not only ensures the high retention of the slit type, but also incorporates the miniaturization of the set screw.
Feature 2: compared with the standard product, the mounting hole of the round flange economy series product is changed from 4-hole to 3-hole, which saves the on-site mounting time.
Although the mounting hole is changed from 4-hole to 3-hole, the performance of the mounting hole is basically the same as that of the standard.
Feature 3: slit shaft support can be connected without damaging the shaft.
Feature 4: because the shaft support of the cast product is formed by molding, the product itself has a certain mold release slope.
Compared with machined products, this product has slightly reduced precision, but it can meet the user needs of customers and its price is very low.
Feature 5: the cast shaft support is formed by molding, suitable for mass manufacturing. MISUMI has a large amount of inventory for it, which can be shipped on the same day.

Dimensional Drawing

Before slotting, the inner hole is machined according to the tolerance of 0~+0.05. After slotting, the inner hole will deform due to stress release, and the tolerance of inner hole will change.

As it is a cast product, the external dimension tolerance before slotting will conform to the casting grade tolerance CT8

Specifications Overview

Type		Material	Surface Treatment	Accessories
Round Flange	Both Surfaces Cut Flange
C-STHWRB	C-STHWCB	Equivalent to SS400	Ferroferric Oxide Protective Film	1 hexagon socket head bolt

Cast, the product has a certain mold release slope.

Precautions

① The machining accuracy of slit shaft support is H7 before slotting, and the inner hole tolerance will become larger due to internal stress release after slotting.
② It is recommended that the shaft support is matched with shaft with tolerance of f8/h5/g6.

Example of Use

Mechanism name: hole groove depth detection fixture
Mechanism function:
Correct workpiece positioning can be continuously performed and the depth of workpiece hole groove can be checked manually.

Function of shaft supports:
shaft supports are used to fix the inspection mechanism for easy disassembly.
