The INA-FAG B71913-C-T-P4S-DBL is a high-precision angular contact ball bearing designed for spindle applications requiring extreme accuracy and rigidity. This genuine FAG bearing features a 65 mm bore diameter, a 100 mm outer diameter, and a 36 mm width. It is a single-row bearing with a contact angle 'C' (15 degrees), 'T' for a phenolic resin cage, and 'P4S' indicating a tolerance class better than P4, suitable for high-speed operation. The 'DBL' configuration signifies a matched pair of bearings arranged back-to-back, providing high axial and radial rigidity. Ideal for machine tool spindles and other precision rotating equipment.
