Cylindrical roller bearing, the rollers and raceways are in linear contact. Consequently this type of bearing can support a larger radial load than a point-contact ball bearing. Also, its structure is suitable for high-speed operation. A cylindrical roller bearing used for the main spindle of a machine tool can have either a double- or single row configuration, and certain variants have a tapered bore so the radial internal clearance can be adjusted.
