Mechanical Lock

Whittet-Higgins has an extensive line of mechanical lock retaining devices, including the Bearlok, Shoelok, and Clampnut. Available in both metric and inch sizes in a variety of materials. Precision bearing threads in Series BL, CNB, NSH, and TLN are manufactured to National Standard Class 3. Precision ISO metric threads in Series BLM, CNM, NSHM, and TLM are manufactured to Class 4H. Unified threads in Clampnut series CNC, CNF, CNS, SNC, SNF, and SNS are manufactured to Class 2B.

• BL Bearlok - The BEARLOK versatile mechanical lock retaining nut adjusts, pre-loads, and secures bearings and other components to the shafts and spindles of power transmission assemblies with the most consistent precision squareness, centreline alignment, and the axial location from loading through locking procedures. Its strong uniform circumferential locking deep into the shaft or spindle threads prevents loosening from vibration, shock, and heavy loads.

Prevailing Torque

Precision bearing threads in Series BH, BHL, BHM, BHS, and BHT are manufactured to National Standard Class 3. Precision ISO metric threads in Series BM, BML, BMM, BMS, and BMT are manufactured to Class 4H. Unified threads in Series BHI are manufactured to Class 3B.

This series of BEARHUG Locknuts, with a nylon collar, is the mainstay of the precision self-locking nuts. It is designed for the same shaft dimensions as are the N and AN locknuts, but with the added features of self-locking and super precision wherein it has become a most important component for precision bearing and power transmission assemblies.
