About Ball and Roller Bearings

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

Ball Bearings
Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings.

High-Load Threaded Track Rollers
With a double row of cylindrical roller bearings, these rollers provide the highest combination of speed and dynamic radial load ratings of any threaded track roller we offer. 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.
Rollers with seal have an end seal to protect the rolling elements from dirt and contamination.

High-Load Shaft-Mount Track Rollers
With a double row of cylindrical roller bearings, these rollers provide the highest combination of speed and dynamic radial load ratings of any shaft-mount track roller we offer. Also known as yoke-style cam followers, these rollers have more mounting flexibility than threaded track rollers. They're typically mounted onto a shaft or clevis rod end.
Rollers with seal are permanently lubricated and have end seals to retain lubricant and protect rolling elements from dirt and contamination.
