About This Product

The HLB uses the same wedge-integrated structure technology as the Hardlock Nut, so it can maintain the initial preload for a long period of time no matter how large a repeated load is applied. This also leads to longer life of rotating bodies and bearings.

■Features

・Wedge-based integration technology maintains initial rigidity and initial preload to prevent damage to bearings: The traditional Japanese technique of driving wedges into the gaps between bolts and nuts integrates screws and prevents them from loosening. The ultimate lock nut that completely eliminates loosening. As a result, an appropriate initial preload amount can be maintained for a long period of time, and various damage to the bearing caused by a decrease in rigidity can be prevented. - Maintains strong detent effect even after reuse. ・The thread shear strength is more than twice that of a general bearing lock nut (in the case of an uneven set): 3.1 Thread shear strength test using a universal testing machine - Compared to a general lock nut made of the same material, the HLB has a lower number of threads when set is approximately twice as high, so the overall thread strength of the nut is also more than twice as strong. 3.2 High load repeated durability test - Using a fatigue testing machine, a high load of 15% (30kN) of the thread shear strength (approximately 200kN for M20) was repeated 1 million times, and both the HLB and bolt were destroyed. That never happened. - Applicable to shafts with key grooves machined as is (does not damage threads): Like regular nuts, the threads of each uneven nut are not deformed, so they can be tightened back dozens of times on shafts with key grooves machined. It will not damage the threads of bolts and nuts even if ・Easy to tighten: The uneven nut does not deform the threads like a general lock nut, so the first nut can be seated in the bearing with finger tightening. You can then easily tighten each nut with a hook spanner. - Capable of handling high loads and adjusting the center of gravity depending on the tightening method: A - If a large load is applied repeatedly, tighten the convex nut with a large number of threads first, then lock the concave nut. B - If it is necessary to adjust the center of gravity of the rotating body, first tighten the concave nut with the chamfer, then gradually tighten the eccentric convex nut to balance the rotating body.
