Stainless Steel Ball Bearings
Bearings are 440C stainless steel for good corrosion resistance.
Open bearings dissipate heat more efficiently than shielded and sealed bearings.
Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings.
Bearings with extended inner ring provide additional shaft support.

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.

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.

Low-Profile Mounted Ball Bearings with Two-Bolt Flange
Designed with a thin, compact housing, these bearings are good for space-constrained applications. Seals block out dust and contaminants.
Stainless steel bearings are more corrosion resistant than steel bearings.
Self-aligning bearings compensate for shaft misalignment.

Miniature High-Speed Threaded Track Rollers
Built to handle high speeds for their size. These track rollers have an outer ring that supports higher speeds than standard-sized track rollers. They also create less friction than miniature high-load rollers while spinning. You can use these rollers for precise movements in robots or other miniature applications.

Thrust-Load-Rated Corrosion-Resistant Threaded Track Rollers
These rollers are rated to handle radial and thrust (top and side) loads simultaneously. Also known as cam followers, track rollers support loads while guiding and positioning work. Thread the stud directly into a component or secure with a nut for through-hole mounting. All rollers are permanently lubricated and have end seals to retain lubricant and protect rolling elements from dirt and contamination.
303 stainless steel rollers are more corrosion resistant than 440C stainless steel rollers.
