HLB® (HARDLOCK BEARING NUT)

●The Hard Lock Bearing Nut HLB®The HLB®

Built with the same powerful, anti-loosening construction as the Hard Lock Nut, the HLB or Hard Lock Bearing Nut provides superior fastening power to prevent bearings from loosening and is highly rated in industry. The internal locking energy is completely unaffected by external shock and vibration, maintaining a completely fastened state.

The HLB is used widely in welding, pressing and lathe machinery as well as equipment for construction, transportation, trains and shipbuilding. The HLB is so well trusted, it is also employed for use in robots and aerospace.

The HLB is maintenance-free and has a stronger fastening force and higher efficiency that other general-purpose nuts. The economic value resulting from the lower total cost meets a strong demand and has built strong trust with industry.

The Hard Lock® Nut protects the public in such applications as

railroads, expressways, bridges, buildings, civil engineering projects, steel towers, railway cars, transportation machines, shipbuilding, atomic power plants, dams, steel-making machinery, metal presses, rock crushers, and other production equipment in major industries

Applications of the HLB®

The Hard Lock® Nut protects the public in such applications as

operational gears, machine tools, bearings for main shafts, bearings for drive components, welding robots, indices, concrete pump trucks, reduction gears, transmissions, general-purpose pumps, clutch brakes, large dump trucks, forklifts, balancers, aerial vehicles, service trucks [NOTE: Cannot find a word specifically meaning a truck with a ladder.
