Timken TW107 Bearing Lock Washer

The Timken TW107 bearing lock washer provides a positive mechanical lock to secure bearing locknuts on shafts and adapter sleeves, preventing loosening from vibration and rotational forces in mounted bearing assemblies. It is designed to work with compatible AN Series and N Series locknuts, featuring 15 tangs that engage both the shaft keyway and locknut slots for secure retention. This steel TW Series washer fits a 35 mm shaft, with an outside diameter over tangs of 57.15 mm, a face diameter of 46.05 mm, and a thickness of 1.57 mm. It is commonly used with spherical roller bearings, adapter sleeves, withdrawal sleeves, conveyors, gearboxes, mining equipment, and other heavy-duty industrial machinery, compatible with TN07 / AN07 locknuts. Maintenance teams, OEMs, and system integrators use this lock washer for replacement, repair, retrofit, and equipment overhaul to ensure secure bearing retention and reliable equipment operation, with replacements such as TW107-2, SKF MB07, and NTN TW107 equivalents.
