About Track Rollers
Also known as cam followers, track rollers have a thick outer roller that runs directly on a flat surface.

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.

Precision Flanged Ball Bearings


When speed and accuracy matter most, opt for these bearings. They’re made to tighter tolerances than standard flanged ball bearings. All are 440C stainless steel for good corrosion resistance. The flange ensures proper positioning inside a tube or housing.
Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings.

Extreme-Temperature Threaded Track Rollers


Lubricated with graphite, these rollers can handle temperatures from -450° to 750° F—the widest temperature range of any track roller in our offering. 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 have end seals to protect rolling elements from dirt and contamination.

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.
