This spindle bearing carries a 25° contact angle and is designed for precise positioning under axial and radial load in a single row angular contact configuration. Bore diameter is 80.0 mm, outside diameter 110.0 mm, width 16.0 mm, and net mass 0.363 kg. The limiting speed reaches 24000.0 1/min, supported by a T cage construction. Manufactured to restricted tolerances (P4S), the bearing is matched and supplied adjusted in pairs or sets, as indicated by the E-T-P4S-UL designation. The restricted tolerances and matched-set arrangement allow this bearing to be mounted in back-to-back, face-to-face or tandem configurations, maintaining defined preload across the set. Without integrated sealing, the bearing depends on external sealing at the housing and relies on correctly metered lubrication suited to high rotational speeds. The T cage supports stable cage guidance at elevated speeds, consistent with the high limiting speed rating specified for this bearing.
