HARDLOCK Bearing Nut (HLB)

Liên hệ

This nut prevents bearing looseness, securely maintaining a near-perfect tightened state. The powerful looseness prevention effect resists vibration due to high-speed rotation and shock caused by forward and reverse rotation even when the preload is low.

Features:

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.
  • Reusable
    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.
  • Economical
    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.

Installation Procedure:

B1: Install the convex nut manually.
B2: Use a hook wrench or other tightening tool to tighten the convex nut to the torque required for the target application.
B3: Make sure that the gap between the convex nut and concave nut is about one thread pitch. Screw the concave (lock) nut onto the convex nut manually until it no longer turns.
B4: Tighten the concave nut in the same way as the convex nut. Use a torque wrench to tighten the concave nut to the recommended torque set by Hardlock. If a torque wrench is not available, tighten the nut manually until it no longer turns, then use a regular tightening tool and tighten the nut at least one full turn (360 degrees) to obtain sufficient locking effect.
When the nuts are tightened correctly, a gap may still remain between the nuts due to the shaft diameter tolerance. Regardless of whether or not there is a gap, the Hardlock Bearing Nut will produce a sufficient locking effect if tightened correctly according to these instructions.
If the bearing is fixed, the convex nut and concave nut can be installed in the opposite order (concave first, convex second) with no reduction in the self-locking effect.
