How to install and remove
How to install and remove SGL-F, SGL-R, SGL-A
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.
How to install and remove SGL-K
After cleaning the external screw, set the YSK lock nut with the tightening bolt loosened. Tighten the tightening bolt diagonally and evenly with a gap of 1~2mm between the end face of the YSK lock nut and the end face of the mating side. Eliminate screw play. After that, loosen the tightening bolt evenly little by little until the YSK lock nut can be turned without rattling. Next, temporarily tighten with an axial force of 2~3 times the required axial force. This is a necessary step for the initial familiarization of YSK lock nuts. Then, loosen the YSK lock nut and retighten it until the proper axial force is obtained. Finally, tighten the 4~8 tightening bolts at right angles and evenly with the appropriate torque to ensure that they are completely fixed with the external screws.
To remove, loosen all set screws sufficiently before loosening the lock nut.
Thread Accuracy
The GLO SGL-F/SGL-R/SGL-A/SGL-K 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.

Description
The SGL-F lock nut is designed to tighten the shaft from three points in the direction at an angle (30 degrees) to the thread. This excellent tightening method provides a high loosening torque and has a very high anti-loosening effect. In addition, this lock nut is ground all over the surface, including the internal thread. Therefore, it is ideal for spindles for high-speed rotation that require high precision.
