This spindle bearing is a single-row angular contact type with a 15° contact angle, designed for adjusted mounting in pairs or sets. It has a bore diameter of 100.0 mm, outside diameter of 150.0 mm, and width of 24.0 mm, with a net mass of 1.25 kg. The bearing features non-contact lip seals on both sides and a T-type cage, manufactured to restricted tolerances for precise running accuracy. The design allows the bearing to be preloaded in matched sets, ensuring consistent stiffness and controlled axial play under operating conditions. The non-contact sealing arrangement reduces friction losses while maintaining protection against contamination, and the restricted tolerance class supports high-speed, high-precision rotation typical of spindle applications requiring stable radial and axial guidance.
