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.

One-Way Locking Ball Bearing Clutches
Internal locking elements (sprags) lock to transmit torque in one direction while turning freely in the other direction. Use them in applications where precision movement is required, such as pick-and-place and automated indexing conveyor systems. Shields keep out dust and contaminants.
For dirty or dusty environments, sealed bearings are the best choice, since they block out contaminants better than shielded bearings.

Needle-Roller Bearings
Also known as drawn-cup roller bearings, these are our thinnest roller bearings. The outer ring is drawn out to form a lip that holds the bearing together. Bearings take on the shape of their housing and may be oblong prior to installation.
Sealed bearings block out dust better than open bearings, but retain more heat.

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.
Crowned rollers have a slight curve, invisible to the naked eye, which helps them stay centered on surfaces that are slightly misaligned or not perfectly flat.
Rollers with seal have an end seal to protect the rolling elements from dirt and contamination.
