The best choice for high-performance bearings and valves, these 440C stainless steel balls are among the strongest, hardest, and most wear-resistant we offer. They’re passivated to wash away surface particles that cause rust, and they’re polished to a mirror-like finish that contaminants can’t stick to. The result is balls that stay smooth and stand the test of time—even at temperatures up to 800° F. They’re made to strict ISO 3290 standards for roundness and surface quality.

These balls are magnetic, so you can use them in separators, sensors, and automated handling systems that use magnetic pickup or positioning.

Whether inside pumps or furnace parts, these balls can be used in any mildly corrosive, high-temperature conditions. Made of 304 stainless steel, they won’t degrade when exposed to mild chemicals and water, even at temperatures up to 1500° F. They’re passivated to wash away surface particles that cause rust, and they’re polished to a mirror-like finish that contaminants can’t stick to. The result is balls that stay smooth and stand the test of time. These balls are made to strict ISO 3290 standards for roundness and surface quality.

Although 304 balls aren’t as wear resistant as 440C balls, they’re easier to fabricate. They’re also nonmagnetic.

Trusted in marine and chemical-processing valves, these balls stand up to some of the most highly corrosive environments. Made of 316 stainless steel, they hold up to sulfuric acid, chlorine, and other harsh chemicals in temperatures as high as 1500° F. They’re a step up from balls made of 304, which have similar strength and temperature performance. They’re passivated to wash away surface particles that cause rust, and they’re polished to a mirror-like finish that contaminants can’t stick to. The result is balls that stay smooth and stand the test of time. They’re made to strict ISO 3290 standards for roundness and surface quality.

Although 316 balls aren’t as wear resistant as 440C balls, they’re easier to fabricate. They’re also nonmagnetic.

Grade 5 is the strongest of all the titanium alloys thanks to its higher aluminum and vanadium content. It offers a versatile mix of good corrosion resistance, weldability, and formability. These balls are made to Grade 200 tolerances.

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.

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 in bearings and in valves.

Seal out air and gas in high-temperature and high-wear applications. This ultrahard ceramic can also be used in applications that require superior strength.

Comparable to Hastelloy C276, these balls resist corrosion from harsh chemicals, such as nitric acid, sulfuric acid, and hydrochloric acid. They’re often used in bearings and valves. They won’t stress crack from contact with sulfides, making them good for use in petrochemical applications. This nickel alloy resists chloride pitting better than stainless steel, and it’s more corrosion resistant than nickel K500.

Often used instead of metal in bearings and rollers, these balls are ideal for applications where strength under heavy loads and wear resistance is needed. It's the addition of yttria that gives this zirconia more strength and lowers the chances of cracking from impact than standard zirconia, alumina, and silicon nitride ceramic. If cracks do occur, they will not spread, extending the life and reliability of the material. It also means this zirconia blend resists wearing down from rubbing against another part or abrasion from chemical slurries.

These balls do not withstand rapid temperature changes or high temperatures as well as other high-performance ceramics such as ceramic alumina and silicon nitride ceramic.

Secure trailers to vehicles by locking the hitch pin into the receiver—you can't disconnect the trailer without the key. Use them to prevent someone from stealing your trailer or moving it. Built to stand up to any weather, they're great for outdoor trailers. The lock body rotates around your hitch pin, so you can easily reach the key into the cylinder to unlock. A plastic cover protects the key cylinder from water and debris, so it won’t freeze, corrode, or jam.
