Angular contact ball bearing 3006-C3 transmits combined radial and axial loads through a double row of balls arranged for contact-angle operation. Bore diameter is 30.0 mm, outside diameter 55.0 mm, width 19.0 mm, and net mass 0.162 kg. The bearing uses a TVH plastic cage, which keeps ball spacing stable at higher speeds while reducing friction and mass compared to a solid cage. Limiting speed is rated at 13500 1/min, with a reference speed of 10100 1/min. The C3 internal clearance is wider than standard, compensating for thermal expansion during operation and allowing the bearing to run with some shaft misalignment or heat buildup without excessive preload. The double-row design supports axial loads acting in both directions, making the bearing suitable where the shaft must be located precisely without a second single-row unit. As supplied without integrated sealing, relubrication and external sealing arrangements must be provided by the housing design, and the plastic cage limits continuous operating temperature compared to metal-cage variants.
