Product Description

The important accuracy requirements of a locknut bearing and the V-thread on a ballscrew or spindle are the fitness between the two and the squareness of the end where the locknut attaches the bearing. These factors directly affect the service life, reliability, and quality of the bearings and the ballscrews/spindles; this, of course, also has an effect on the image and quality of your products.

Our High Precision Lock Nuts are specially produced to meet your high demanding requirements.

Features:

Our K series Clasp Locking Precision Lock Nuts use the elasticity of the steel body itself, axial lockings and forced locking. The locking capabilities of this series are more than three times higher comapred to the traditional lock nuts. The K series precision lock nuts use 4 to 8 high-strength screws to lock the threads through axial deformation. It is suitable for harsh working conditions where locknuts are easily loosened and high torque is required. The deflection accuracy of the nut can be adjusted by adjusting the tightening force of the axial screws.
