The diameter on these balls is held to a precise tolerance.

These balls are hardened for increased wear and abrasion resistance.

440A stainless steel resists damage from impact and abrasion. It's often used for cutlery and valve components.

The addition of molybdenum gives 316 stainless steel excellent corrosion resistance. Use it in a variety of marine and chemical-processing applications.

Hollow construction reduces weight and allows these balls to float.

To increase strength and hardness, these K500 nickel balls contain titanium and aluminum. Comparable to Monel, they hold up to harsh chemicals and resist chloride stress corrosion better than stainless steel. They’re often used as bearings and in valves.

Among the strongest plastic materials we offer, Torlon PAI has a slippery surface that resists wear. Use it to make high-friction compressor parts, bearings, and seals.

Also known as nylon 6/6, this general purpose material is often used for bearings, gears, valve seats, and other high-wear parts.

Practically nonabsorbent, HDPE won't swell when exposed to moisture. It is denser and more rigid than LDPE, plus it's more chemical resistant.

At only half the weight of glass, polycarbonate maintains excellent impact resistance across a wide temperature range. It's comparable to Lexan, Hyzod, Tuffak, and Makrolon.
