Locknuts - Stainless Insert


Simplify the assembly and reduce costs involved in securing ball bearings. One piece item where the locking function is performed by a spring peened into the top of the nut.

Nut Body: Low Carbon Steel. Locking Insert: Stainless Steel Hardness HB 201-269. The spring bears on the flank of the shaft thread with force (P) generating reaction force (Pí) in the screw threads with a resulting high friction torque (prevailing torque). Unique slim body design. Secure locking without keyway and tab washer. One piece construction reduces stock and allows simpler, quicker assembly. Simple infinite adjustment. Re-usable up to 100 times. Resists vibration and shock. Equally effective for rotation in either direction even with rapid reversals.
