Description
Tapered roller bearing 30303-A separates inner assembly with cone and roller set from the outer cup, allowing independent mounting of both components. Main dimensions follow DIN 720: bore diameter 17.0 mm, outside diameter 47.0 mm, net mass 125.0 g, single row of tapered rollers, standard cage, limiting speed 17600.0 1/min. The separable construction simplifies fitting and adjustment of internal clearance during assembly, since the cup can be installed separately from the cone unit. The tapered roller and raceway geometry allows the bearing to carry combined radial and axial loads acting in one direction; for full axial support in both directions a second bearing arranged in an opposed configuration is required. No integrated seals or shields are provided, so external sealing and lubrication supply must be arranged in the housing design.
