The 71914AC is a P4 precision angular contact ball bearing with a 25 degree contact angle, built for spindles that demand rigidity and accuracy. A 70 mm bore, 100 mm outside diameter and 16 mm width deliver a basic dynamic load rating of 31.5 kN and a static rating of 31.0 kN, enough for heavy cutting and stiff preload. The larger 25 degree angle raises axial stiffness, so the bearing resists deflection under thrust load while holding P4 runout for accurate surface finish. It
