Precision Balls
All of our products are qualified through our A2LA lab, the only accredited lab for sphericity in the United States. We also supply customers who require DFARS, Lockheed and NADCAP compliance. For our automotive program, all our heat treat suppliers have been audited by an accredited 3rd party auditor approved by Ford, GM and Chrysler and are in full compliance. We can leverage over 45 years of application experience and rapid prototyping to provide the right standard or custom solution to your project. And we are ISO 9001:2000 resgistered to ensure consistency and quality in all operations.
We offer ball sphericity within 3 millionths of an inch (0.077 micron), 100% quality inspection, and a choice of over 27 high performance materials - all guaranteed to meet or exceed the standards of the American Bearing Manufacturers Association (ANSI/ABMA Std 10 - 1989).
We manufacture in Bristol, CT, and also import semi-finished products from low cost regions and do the finishing in our Bristol plant to guarantee product quality.
Below is a list of our most common products (other materials are available upon request)
Chrome Steel 52100
52100 chrome steel is found primarily in ball bearing designs and a variety of demanding industrial applications. A vacuum-degassed AISI E52100 chrome steel is used to obtain a superior ball with a fine surface finish, through-hardness and high load capacity. Also available in consumable electrode vacuum melt material.Learn more >
Stainless Steel
These quality stainless steel balls are available for applications in corrosive environments. AISI Type 440C offers the greatest hardness and surface finish, and is available in double vacuum melted materials. AISI Type 302 provides extreme toughness and corrosion resistance from oxidizing solutions and many organic chemicals in an unhardened state.
For resistance to sulfuric acid compounds and other severely corrosive environments, Type 316 austenitic steel with increased nickel is available.Learn more >
Silicon Nitride Ceramic
Popular choice in bearing designs and other high precision applications. When compared to steel, this material offers 60% reduction in weight, up to twice the material hardness, a coefficient of thermal expansion that is 70% less than steel, and a temperature operating range up to 1800° F.Learn more >
Monel & K-Monel (Nickel Alloy)
Monel and K-Monel balls are the ultimate in resistance to corrosion from steam, gas, salt water, ammonia, calcium chloride, acidic foods, high temperatures and other extreme environments.Learn more >
Brass
Corrosion resistant material similar to bronze, with greater tensile and yield strength.Learn more >
Bronze
A high quality alloy created for environments attacked by water, gasoline, and certain solvents.Learn more >
Titanium
This highly inert material is lightweight, offers exceptional anti-corrosive properties, operates effectively in high temperature applications, provides a high level of tensile/compression strength, and has expansion characteristics similar to steel. Titanium is used extensively in aerospece applications as well as in the chemical, food processing, and medical implant industries.Learn more >
Carbon Steel
These balls are substantially cheaper than balls manufactured from chrome steel. They can be case hardened (soft core), ideal for use with medium loads, or through hardened, which have longer life and load capacity.Learn more >
Glass
Glass balls offer high corrosion resistance and can be exposed to temperatures up to 600° F.Learn more >
Specialty
We can provide subassemblies or complete solutions that combine Danaher's broader capabilities with Thomson's ball technology.Learn more >
