Bearing locking nut that stably maintains a completely secured state
A bearing locking nut developed based on the wedge structure of the hard lock nut, which provides a powerful thread-locking effect.
Provides a thread-locking effect that is unaffected by vibrations from high-speed rotating or shocks from forward and reverse rotation.
Thread-locking Structure
By combining the offset processed convex nut 1 and the precisely round processed concave nut 2, a powerful lock effect is generated in the direction perpendicular to the shaft axis based on the wedge principle.
The powerful thread-locking effect of the wedge in the HLB, just like the hard lock nut, fully integrates the shaft and nut, preventing any impact or vibration from high-speed rotation.
The HLB provides the same thread-locking effect and squareness accuracy regardless of whether it is secured from the convex or concave side. However, for applications with higher load, fastening from the convex nut side is recommended.
