Main applications
Tightening nuts for bearings for machine tool spindles.
Tightening nut for ball screw support bearings.
Tightening nuts that require precision or where you want to reduce adjustment time.
How to install and remove
For installation, after cleaning the external thread, first set the lock nut. Then, to prevent loosening, loosen the 3 anti-loosening set screws attached to the nut 0.5~1 times. After that, tighten the first set screw until it stops lightly, then tighten the second and third screws sequentially at the specified tightening torque, and then the first set screw The installation is completed by tightening at the same specified torque.
To remove it, first loosen the three set screws sufficiently. At this point, the locking metal at the end of the set screw engages with the thread Since it is in a state, tap it lightly with a hammer from the side, make sure that the locking metal is free, and loosen the lock nut.
Thread Accuracy
The GLO M-YSA/M-YSR/M-YSF type lock nuts are finished in ISO 4H rating. Therefore, we ask that the screw accuracy of the shaft be finished to 4H grade. As a result, there is no need for post-integration adjustments, and high accuracy is maintained.
