Stainless Steel Ball Bearings
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.

Flanged Ball Bearings
The flange ensures proper positioning inside a tube or housing.
440C stainless steel bearings are more corrosion resistant than steel bearings.
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.

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.
