Carries radial loads within a compact cross-section, using full-complement or cage-guided needle rollers running directly against the shaft seat, which keeps the outside diameter down to 14.0 mm and net mass to 6.75 g. This needle roller bearing of the light series is fitted with a TV cage that guides and separates the rollers, allowing operation up to a limiting speed of 34500 1/min and a reference speed of 43000 1/min. The absence of an inner ring means the shaft raceway must be hardened and ground to the correct tolerance, so mounting accuracy directly affects running behaviour. The light series cross-section and TV cage suit applications needing high radial load capacity per unit of installation space, with lubrication supplied either as grease or oil depending on the operating speed and temperature range required.
