This is a single row angular contact ball bearing with a 65.0 mm bore, 140.0 mm outside diameter, and 33.0 mm width, weighing 2.13 kg. It belongs to the X-life design line (XL), which provides increased load carrying capacity through optimized internal geometry. The bearing uses a TVP cage made of plastic, guided on the balls, which reduces friction and mass compared to a solid metal cage. Limiting speed is 6500 1/min, with a reference speed of 5000 1/min. The single row angular contact design allows the bearing to carry combined radial and axial loads in one direction, making paired mounting suitable where axial loads act from both sides. The plastic TVP cage contributes to smooth running and lower operating temperature at higher speeds, supporting the stated reference speed value. As supplied without seals or shields (open design, TVP), the bearing requires external sealing and a separate lubrication arrangement suited to the operating conditions and speed range indicated.
