Permanently Lubricated Ball Bearings

A solid polymer lubricant surrounds the balls, eliminating the need for additional lubrication. Because it's solid, the lubricant blocks out water and dust, extending the life of the bearing.

Stainless Steel Ball Bearings

Bearings are 440C stainless steel for good corrosion resistance.

Open bearings dissipate heat more efficiently than shielded and sealed bearings.

Permanently Lubricated Stainless Steel Ball Bearings

A solid polymer lubricant surrounds the balls, eliminating the need for additional lubrication. The solid lubricant blocks out water and dust, extending the life of the bearing.

Sealed bearings have even better resistance to dust and contaminants than open bearings.

Ultra-Corrosion-Resistant Stainless Steel Ball Bearings

These 316 stainless steel bearings are more corrosion resistant than our other stainless steel bearings, but they have a lower load capacity.

Plastic Ball Bearings

These acetal bearings have good all-around corrosion and chemical resistance.

316 stainless steel balls have excellent corrosion resistance.

Glass balls have even more corrosion resistance than stainless steel balls.

High-Load Plastic Ball Bearings

With two rows of balls, these lightweight bearings have greater durability and load capacity—and a wider profile—than single-row plastic bearings. They’re commonly used in bottle-filling machines and other food-processing applications. The acetal body doesn’t absorb water, so it can operate in liquids or be washed down without losing strength. The balls are made of either glass or 316 stainless steel—both materials are corrosion resistant. Since there’s no metal-on-metal contact between the balls and the body, these bearings don’t require lubrication.

Water-Resistant Plastic Ball Bearings

Made of PVDF, these bearings resist moisture absorption, so they won’t warp in underwater applications. They also have excellent chemical and corrosion resistance.

Lubrication-Free Plastic Flanged Ball Bearings

Install these acetal bearings in caustic environments and where lubrication can’t be used. They have good all-around corrosion and chemical resistance. The flange ensures proper positioning inside a tube or housing.

High-Temperature Ball Bearings

Open

Made with either PEEK or graphite, these ball bearings work in applications that are too hot for most other ball bearings.

PEEK bearings handle temperatures almost twice as high as that of our other plastic ball bearings. They also have good chemical resistance and excellent corrosion resistance.
