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.
Sealed bearings block out dust and other contaminants better than open and shielded bearings, but retain the most heat.

Permanently Lubricated Ball Bearings
A solid polymer lubricant surrounds the balls, eliminating the need for additional lubrication. Because it's solid, the lubricant blocks out water and dust, extending the life of the bearing.
Sealed bearings have even better resistance to dust and contaminants than 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.

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.

Shaft-Mount V-Groove Track Rollers
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 are for use with Angle Rails for V-Groove Track Rollers. They handle radial and thrust (top and side) loads and work well in dirty environments because debris falls off the angled rail. All rollers are permanently lubricated.
Sealed rollers block out dust and other contaminants better than shielded rollers, but they hold more heat. Their seals also help retain lubricant.
