- Delicate enough for miniature ball bearings
Since 1961, USA Tolerance Rings has produced tolerance rings across a variety of applications & industries.
We’ve remained the ONLY domestic manufacturer of tolerance rings; made in our New Jersey factory.
Tolerance Ring Types
AN rings have corrugations that face inward. They are designed to fit outside a nominal circumference of a cylindrical part.
BN rings feature corrugations that face outward. Their rings are cut to fit inside a nominal circumference.
ANL rings are light-duty versions of AN rings made with very thin material. ANL rings do not maintain a circular shape in their free state.
