FAG HC7016-EDLR-T-P4S-UL is a single-row hybrid ceramic spindle bearing for high-speed machine-tool and grinding-spindle applications. Its designation specifies the contact angle, direct-lubrication arrangement, precision class, universal matching and light preload. Product identification Brand FAG (Schaeffler) Item number HC7016-EDLR-T-P4S-UL Category Single-row angular contact ball bearing / spindle bearing Dimensions and weight Bore diameter (d) 80 mm / 3.1496 in Outside diameter (D) 125 mm / 4.9213 in Width (B) 22 mm / 0.8661 in Weight 0.83 kg Design characteristics Bearing design High-speed hybrid spindle bearing Rolling elements Ceramic balls Seal arrangement Open / no seals Cage TB hard-fiber cage; textile laminated phenolic resin, outer-ring guided Precision P4S Contact angle 25° Matching Universal matching Preload UL — light preload when fitted as a pair in O or X arrangement Lubrication design DLR — direct lubrication through the outer ring with integral O-ring arrangement Reference engineering data Basic static radial load rating C0r 19,700 N Basic dynamic radial load rating Cr 28,500 N Reference limiting speed, grease 18,000 rpm Reference limiting speed, oil 28,000 rpm ECLASS / ECLASS2 23-05-08-03 Speed values are reference data under the manufacturer’s stated test and lubrication conditions. Permissible operating speed must be checked for the actual spindle arrangement, preload, lubrication, temperature and load. Designation guide E: 25° contact angle. DLR: direct lubrication arrangement with integral O-ring provision. T: outer-ring-guided textile laminated phenolic resin cage. P4S: super-precision dimensional and running-accuracy class. UL: universal matching with light preload in a paired arrangement. Application and ordering The hybrid construction supports high-speed spindle operation with reduced frictional heat and wear compared with an otherwise comparable all-steel design. Typical applications include precision machine-tool spindles and grinding spindles requiring high running accuracy and rigidity. Before ordering, confirm the complete designation, quantity, bearing arrangement, lubrication method, spindle or machine model and delivery location.
