This is a spindle bearing designed for precise axial and radial positioning under a 15° contact angle, matched for mounting in pairs or sets. Bore diameter is 17.0 mm, outside diameter 40.0 mm, width 12.0 mm, and net mass 0.06 kg. The bearing is fitted with a T cage and has no sealing, corresponding to the B7203-C-T-P4S-UL execution with restricted tolerances. The restricted tolerance class supports high running accuracy and consistent preload when the bearing is paired or set-mounted, making it suitable for arrangements requiring precise axial control at a 15° contact angle. As the bearing is unsealed, external sealing and lubrication supply must be provided by the housing design. The paired/set configuration allows stiffness and preload to be defined by the mounting arrangement rather than by a single bearing alone.
