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 fabricated to meet your demanding requirements.
