Two rows of balls run on a common spherical raceway in the outer ring, allowing the inner ring with shaft to swivel relative to the housing bore and compensate for angular misalignment and shaft deflection. The bearing 2203-TVH-C3 has a bore of 17.0 mm, outside diameter of 40.0 mm, width of 16.0 mm and a net mass of 0.085 kg. The cage is made of glass-fibre reinforced plastic (TVH), and radial internal clearance is C3, wider than normal. Limiting speed is 19100 1/min, reference speed 17400 1/min. The C3 clearance offsets the fit-up interference and thermal expansion typical of tighter mountings, keeping the bearing free of preload once installed. The plastic TVH cage runs with low friction and reduced mass, supporting the stated speed ratings, while the self-aligning design tolerates shaft bending and housing misalignment without edge loading of the balls. As supplied, the bearing is open and requires separate sealing and lubrication arrangements suited to the application.
