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

Precision Ball Bearings
For greater accuracy and higher speeds, these bearings are made to tighter tolerances than standard ball bearings.
Shielded bearings dissipate heat more efficiently than sealed bearings.
Sealed bearings block out dust and other contaminants better than shielded bearings.

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.
