Cylindrical Roller BEARINGS
High-capacity bearings with cylindrical rollers that give line contact with the raceways, delivering high radial load capacity, rigidity and dependable performance at high speeds in motors, gearboxes, pumps and heavy machinery.
Understanding the
Cylindrical Roller Bearing
Cylindrical roller bearings are rolling-element bearings designed to carry heavy radial loads at high speeds. Their cylindrical rollers make line contact with the raceways, spreading the load over a larger area and giving higher load capacity and rigidity than ball bearings of the same size.
BEARING CONSTRUCTION: Cylindrical rollers are guided between the inner and outer rings by a cage, with flanges on one or both rings keeping them aligned. This line-contact design carries heavy radial loads with low friction, and many designs allow the rings to be separated for easy mounting and dismounting.
Cylindrical Roller Bearings
Every element works together to carry heavy radial loads with controlled, efficient rotation.
Inner Race
The inner ring fits on the rotating shaft and provides the raceway for the rollers.
Outer Race
The outer ring sits in the housing and guides the rollers along its raceway.
Cylindrical Rollers
Precision rollers make line contact with the races, giving high radial load capacity.
Cage / Retainer
Keeps the rollers evenly spaced and parallel to the shaft axis during operation.
