USA Tolerance Rings is the ONLY domestic producer of tolerance rings. All of the rings we sell are made in-house at our NJ facility by our trained technicians. We respond to customers, large and small, with efficient, courteous service and with rapid turnaround of sample parts and with development testing in customer components. This offers a level of precision and quality control that few can offer, while delivering fast turn around and shipping. This benefits clients working on prototypes as well as projects with domestic parts-sourcing requirements. 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.
