SKF Lock nuts with integral locking
KMK and KMFE lock nuts are locked on the shaft (sleeve) by friction. The friction, and therefore the loosening
torque, varies as a result of the accuracy of the tightening torque of the set screw, the surface finish of the shaft (sleeve) thread, the amount of lubricant on the thread, etc. The lock nuts should be properly mounted to threads that are dry or only have a minimum amount of lubricant on them.
