With a diameter that’s held to a close tolerance, this material is hardened for increased wear and abrasion resistance.

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

Also known as chrome steel, 52100 is an extremely hard and wear-resistant material. These balls are often used in bearings.

Also known as mild steel, use these low-carbon steel balls in parts that don't require high strength.

Hollow construction reduces weight and allows these balls to float.

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.

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.

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.

Often used to create bearings, silicon-nitride ceramic is harder than many types of bearing steel but is lightweight and can be easily polished. It also withstands high temperatures.

Also called Pyrex and Schott glass, these glass balls resist clouding and pitting and are highly chemical and heat resistant.
