This benefits clients working on prototypes as well as projects with domestic parts-sourcing requirements.

Our Product

Tolerance rings are tough enough for off-highway equipment, but delicate enough to center a miniature ball bearing. Today, you'll find them in numerous manufacturing applications from home appliances to automotive to electronics. Some of the core uses are mounting bearings, torque transfer, and fastening/ joining.
