The FAG HCS71920-E-T-P4S-UL is a high-precision hybrid angular contact ball bearing, specifically engineered for demanding machine tool spindle applications. This FAG bearing features ceramic rolling elements and steel rings, providing superior speed capabilities, enhanced rigidity, and reduced friction and heat generation compared to conventional all-steel bearings. It has a 25° contact angle (E), a textile laminate cage (T), and P4S-UL precision, indicating increased accuracy and a universal design for paired mounting with a light preload. This configuration ensures optimal performance, high reliability, and extended service life in high-speed, high-accuracy operations.
