Description

Precision Lockwasher Specifications

Precision lockwashers are designed for use with Whittet-Higgins precision bearing locknuts. The inner tab engages with a keyway on the shaft while the outer tab bends into a slot on the locknut, providing positive anti-rotation locking to maintain bearing preload accuracy.

Manufactured to tighter tolerances than standard lockwashers, these precision components ensure that the bearing assembly maintains its critical positioning and preload settings during operation.
