This self-aligning ball bearing carries a spherical outer raceway that lets the outer ring articulate relative to the inner ring, compensating for shaft misalignment and housing bore inaccuracies. The 1200-TVH has a bore diameter of 10.0 mm, an outside diameter of 30.0 mm, a width of 9.0 mm, and a mass of 0.033 kg. It runs with a glass fibre reinforced plastic cage (TVH) and features a cylindrical bore (Z). Limiting speed is rated at 29500 1/min, with a reference speed of 22100 1/min. Internal clearance corresponds to CN (Group N), the normal clearance range, suiting standard fit and load conditions without additional adjustment. The plastic cage keeps friction and mass low, supporting the stated speed ratings, while the self-aligning design allows the bearing to accommodate shaft deflection and angular misalignment without inducing additional internal stress. As supplied, the bearing is open and requires separate lubrication and sealing arrangements to match the operating environment.
