STK351 Expansion Sleeve Shaft Locking Device Assembly Bore Diameter

STK351 Expansion Sleeve Shaft Locking Device Assembly Bore Diameter 5-70mm SCE201 Z8B KL201 MLM Fastening Sleeve CNC Tool

STK351 type expansion sleeve is equipped with a notch on the shoulder of the inner wheel, and the locking bolt enables the inner bushing to be crimped with the inner hole of the coupling shaft, thus controlling the runout of the end face and outer diameter of the coupling shaft, which has a good centring effect.

When locking the bolt, the wheel hole does not move axially and the product is free of play.
