Tapered Bore Self-Aligning Ball Bearings
For use on tapered shafts and round shafts with adapter sleeves, these ball-bearings have a spherical raceway to compensate for shaft misalignment.

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.
