2001-5001
Retaining rings for bores - bowed

Retaining rings 2001-5001 are safety elements for bores in inch dimensions. Their geometric shape is similar to 2000-5000 but the ring is bowed.
This feature provides the ring with more elasticity in order to compensate small axial plays.
They can be produced and supplied only upon customer's request.
