Precision lock nuts with axial locking screws
Precision lock nuts in the KMD series (fig. 1) are preloaded with axial locking screws. After the front part of the lock nut is tightened against the bearing, the axial locking screws on the rear part are tightened (fig. 2). This preloads the threads and generates sufficient friction to prevent the nut from loosening under normal operating conditions (→ Loosening torque).
Installing and removing KMD lock nuts is simple and the axial location effective and reliable. It is possible to make micro adjustments of the axial position using the locking screws (→ Installation and removal).
