The globally recognized HLB Hardlock Bearing Nut

The HLB Hardlock Bearing Nut was developed with the same wedge design as the HLN Hardlock Nut and maintains an extremely effective self-locking effect. This powerful effect ensures a fully tightened state even during high-speed rotation, vibration, forward and reverse rotation and impact. We guarantee significant cost savings since it is maintenance-free.

Powerful self-locking effect
Just like the HLN Hardlock Nut, no matter the conditions the self-locking effect remains secure.

Torque and axial force control
Can be completely locked in the middle of the shaft, and adjustable positioning is also possible.

Made of all metal with little few wear surfaces, sustains a powerful self-locking effect.

Easy and efficient
Can be easily installed with just one commercially available tool.

There are no washers or other self-locking components, and no additional processing is required. Switching to the HLB has the benefit of significant total cost reduction.

Self-locking design

self-locking design 01

The convex nut (A) is designed with an eccentric boss that fits with the circular concave nut (B) to lock onto the shaft using the wedge principle.

self-locking design 02

Due to the strong locking force created by the wedge of the HLB Hardlock Bearing Nut, the self-locking effect stays intact even if exposed to extreme impact caused by high-speed rotation.

self-locking design 03

The HLB Hardlock Bearing Nut demonstrates a high self-locking effect regardless of whether the concave or convex nut is tightened first since there is no effect on the perpendicular accuracy.
