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.

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
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.
