Tolerance Rings:Your IDEAL Solution for Miniature Ball Bearing Designs

• Made especially for miniature and small-sized ball bearings, up to 30mm in outer diameter.

• Ideal for high-precision and high-speed rotating components to ensure rotational accuracy.

• Customizable for a wide range of applications and sizes

USA Tolerance Rings:The leader in custom made tolerance rings

Since 1961, USA Tolerance Rings has been producing tolerance rings for numerous industries. We’ve remained a flexible company that specializes in custom solutions for our clients’ specific engineering needs; utilizing custom as well as in-stock ring sizes for various applications.

All of the rings we sell are made in-house at our New Jersey 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 turnaround for prototypes and domestic parts-sourcing requirements.

USA Tolerance Rings is not just a parts supplier, we’re a design solutions partner. Our in-house engineers work with you to source the exact ring to meet your specific needs and goals. When customers present us with a bearing or part assembly problem, we analyze the design and develop engineered solutions that work for your needs.

PROUDLY MADE IN THE USA!

How they work:Tolerance Ring waveforms are designed to exert a holding force yet allow for ease of assembly between mating components. This closed wave configuration is typically very strong with the strongest part being the shoulders or closed ends of the wave. When the Tolerance Ring is assembled between mating components each wave is elastically deflected resulting in holding force. The holding ability of the ring is the resultant force of all the waves and the coefficient of friction with the mating components.

Benefits of Using Tolerance Rings with Miniature Ball Bearings:

Eliminates:• Outer race rotation• Vibration and noise• Fretting • Need for adhesives

Addresses:• Thermal growth concerns• Corrosion in harsh environments• Need to lower installation forces

when press fit is not desired

Precision instrument applications:• Electrical control systems

• Flow controls

• Gyros, synchros and servos

• Handheld medical devices

• Household electrical appliances

• Motors & Power tools

• Robotics used in high-precision assembly lines

• Telecommunications equipment

AN rings have corrugations that face inward. They are open in the free state, so that when installed inside a bore, the ring conforms to the bore and is self-retaining.

ANL rings have corrugations that also face inward and are light-duty versions of AN rings. The mate-rial that is used is very thin, so ANL rings do not maintain a circular shape in their free state.

Both styles of ring are meant to be used with miniature ball bearings. These light duty rings are used primarily where installation forces must absolutely be kept to a minimum and where the ring will see low radial loads.

Custom Design We custom unique ring configurations for each miniature ball bearing application, allowing our customer’s design engineers to solve the most complex and challenging mechanical applications.

All of our tolerance rings are made and shipped from our facility in Pennington, New Jersey.

Types of Tolerance Rings Used with Miniature Ball Bearings

Our approach: • Customize a ring that will fit a designer’s

existing components to save re-machining costs.

• If using existing parts is not possible, we will suggest a ring configuration and component inner and outer diameters

• Performance test each prototype lot to ensure a perfect fit in a customer’s components.

• Quickly turn around of samples to keep a design moving forward
