Single row cylindrical roller bearing
Structure and Characteristics
Since the rollers of the cylindrical roller bearings make line contact with the raceways, these bearings can support heavy radial loads and are suitable for high speed operation. Assembly and disassembly are comparatively easy even if the inner or outer ring requires a shrink fit, as the
bearing is a separation type.
