Loose needle bearingssizes

Radial needle roller and cage assemblies have a steel cage that provides both inward and outward retention for the needle rollers. The sizes are ranging from 3 mm to 165 mm bore (0.1181 – 6.4961 inch). The designs provide maximum cage strength consistent with the inherently high load ratings of needle roller bearings. Accurate guidance of the needle rollers by the cage bars is allowing these bearings to operate at high speeds. Also available are needle roller and cage assemblies using moulded, one-piece glass-reinforced engineered polymer cages. Needle roller and cage assemblies are manufactured with either one or two rows of needle rollers.
