When to use set screw locking on bearings?
Set screw locking is the least reliable method of securing a bearing to a shaft. It should only be used on low torque (like rotary switches on electronic instruments) and low speed (less than 20 rpm)
What’s the locking method for a step shaft?
The common locking method for stepped shafts is to use a cylindrical bearing seat and an interference fit between shaft seat and bearing inner ring, and a lock nut to secure the bearing axially. For detailed information, refer to Bearing interfaces within the Bearing selection process.
Where are the rollers on a rolling element bearing?
A rolling- element bearing, with balls or rollers, is captured in the pillow block. The bearing inner ring is extended on one side of the shaft. The inner ring is drilled and threaded to accept one or two set screws that grip the shaft with friction such that the shaft and bearing inner ring rotate together.
What happens to the shaft when the bearing is set?
The shaft continues to spin at full speed driving the load, while the bearing inner ring slows. There is a grinding action of metal on metal. 7. The shaft steel, being softer than the hardened inner ring, has more material removed faster, and becomes the sacrificial victim.

How do you lock a SKF Bearing in place?
Using lock nuts and locking plates to lock a bearing +. With the bearing or component in position, screw the lock nut into place. Tighten the nut against the bearing or component with an impact spanner.
