SUC insert limiting speeds
The limiting speed of any ball bearing insert is, for practical purposes, determined by the quality of fit between the inner ring and the shaft.

Setscrew tightening torque
The 2 setscrews should be tightened to the appropriate torque figure. Over tightening may result in a fracture developing in the inner ring.
Should the axial load be high, a small dimple in the shaft may improve the locking effect. For best effect the bearings should be mounted against a shoulder in the shaft.
