This double row angular contact ball bearing transmits combined radial and axial loads in both directions through its two rows of balls arranged at a contact angle. Bore diameter is 80.0 mm, outside diameter 140.0 mm, width 44.4 mm, and net mass is 2.32 kg. The bearing uses a TVH cage made of plastic, which reduces friction and mass compared to solid cages. Limiting speed is rated at 4900 1/min, with a reference speed of 5100 1/min. The C3 internal clearance is larger than standard, compensating for thermal expansion under operating conditions and allowing a tighter fit without eliminating internal clearance. The double row design provides high axial rigidity in both directions from a single bearing position, making it suitable for shaft arrangements where axial loads act alternately or simultaneously from both sides. The plastic TVH cage supports smooth ball guidance at the stated speed ratings and is compatible with grease lubrication under normal operating temperatures.
