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, electroless nickel plating and clear anodizing is available, in which electroless nickel plating and clear anodizing have 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.

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.

Precautions of Shaft Supports

①It is slit type, and the tolerance H7 of mounting hole D is that before cutting open end, which may increase to approx. H8 due to internal stress release after cutting open end.
②It is recommended that the Shaft Supports is matched with shaft with tolerance of f8/h5/g6. For details, click
