30210J is a tapered roller bearing (metric, ISO 355), 50 mm bore × 90 mm OD × 21.75 mm wide (1.9685 × 3.5433 × 0.8563 in). It has a pressed steel cage. Published interchange tables list it as equivalent to SKF 30210J, TIMKEN 30210.
The 30210J is a metric tapered roller bearing with a 50 mm bore diameter, designed to accommodate combined radial and axial loads in a single direction. The tapered geometry allows the bearing to handle thrust loads while maintaining high radial load capacity.
