Shaft Supports Space-saving Slit Cast Product (C-STHWRB15)
Part Number
Configured Part Number is shown.
C-STHWRB15
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 CT8Specifications Overview

Cast, the product has a certain mold release slope.Precautions
② It is recommended that the shaft support is matched with shaft with tolerance of f8/h5/g6.

Frequently asked question (FAQ)
- Question: Why does the locking screw always slip when locking the guide shaft?
- Answer: 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.
- Question: What is the verticality between the mounting surface of MISUMI shaft support and the inner hole?
- Answer: The verticality between the mounting surface and the inner hole is less than 0.02.
- Question: What is the surface treatment of MISUMI shaft support? What is the anti-rust performance?
- Answer: Surface treatment of black oxide and electroless nickel plating is available, and electroless nickel plating has better anti-rust performance.
- Question: When fastening the guide shaft with the shaft support, how can the guide shaft be fastened without damaging the guide shaft?
- Answer: Locking screws with brass or urethane heads can be used for fastening to reduce damage to the guide shaft.
