This spindle bearing is designed for precise shaft positioning under a 25° contact angle, with a bore of 45.0 mm, outside diameter of 75.0 mm, and width of 16.0 mm, giving a net mass of 231.51 g. It features a T-type cage and non-contact lip seals fitted on both sides, matched to restricted (P4S) tolerances for accurate running. Supplied as B7009-E-2RSD-T-P4S-UL, matched and intended for mounting in pairs or sets to achieve defined preload conditions. The non-contact seal design limits friction and heat generation, while the restricted tolerance class supports high-precision rotation with reduced radial and axial runout, suited to arrangements requiring stable stiffness and controlled clearance under adjusted mounting.
