This steel lock washer, featuring an 85 mm inside diameter and a 119 mm outside diameter, prevents accidental loosening effectively. The inner tab engages the shaft keyway, allowing you to easily bend an outer tab into a slot on the lock nut for an immediate positive lock. This maintains axial bearing position and helps you prevent costly unplanned machine downtime.
