This double row angular contact ball bearing carries axial loads in both directions combined with radial loads, achieved through its two rows of balls arranged at a contact angle. The bearing has a 55.0 mm bore diameter, 100.0 mm outside diameter, and 33.3 mm width, with a net mass of 0.93 kg. It features a TVH cage made of glass-fibre reinforced plastic, part of the X-life design line, allowing a limiting speed of 7100 1/min and a reference speed of 7200 1/min. The double row design provides a rigid bearing arrangement suitable for shafts requiring precise axial guidance without a paired counterpart, since both load directions are handled within a single unit. The plastic cage reduces friction and mass compared to solid cage designs, supporting the higher speed capability, while the X-life execution indicates tighter manufacturing tolerances on raceways and rolling elements for improved running accuracy and load distribution. As supplied open, the bearing requires external sealing and a lubrication method appropriate to the application speed and operating temperature.
