The HARDLOCK® Bearing Nut was developed with the same wedge design as the 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 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 HARDLOCK® Bearing Nut has the benefit of significant total cost reduction.
