Lock Nut / Lock Washer

Description

Lock nut / Lock Washer

Lock Nut: Most commonly used locknuts, made of low carbon steel, these locknuts are the least expensive but require a lockwasher and the cutting of a keyway in the shaft.
This series meeting SAE-Society of the Automotive Engineers, ABEC-Annular Bearing Engineers Committee and AFBMA- Anti-Friction Bearing Manufacturers Association specifications offers a positive mechanical lock when combined with a lockwasher and keyway.

Lock Washer:  Most commonly used lockwashers, these multi-tang lockwashers are the least expensive. They are made of a material sufficiently soft so the tangs will withstand several bends of locking and unlocking in assembly, but of a material sufficiently hard to resist the shearing action which may be exerted by the corner of the spanner slots. The key is bent in the opposite direction of the tang and axially to the shaft to fit in a shaft keyway under the bearing race to provide greater resistance to the shearing action and to provide support with the inner race of the bearing.
