Single Row Tapered Roller Bearing – 30209

The 30209 is a single row tapered roller bearing engineered for robust performance under combined radial and axial loads. Its separable inner ring, rollers, and cage allow for flexible mounting, dismounting, and maintenance, making it ideal for applications requiring precise alignment and easy serviceability.

With a 45 mm bore and 85 mm outside diameter, this bearing offers a basic dynamic load rating of 81.6 kN and a static load rating of 76.5 kN. The 15.109° contact angle supports axial loads in one direction, while the bearing operates reliably at reference speeds of 6,300 r/min and limiting speeds up to 8,000 r/min.

Constructed from high-quality bearing steel with a sheet metal cage, the 30209 provides low friction, long service life, and the option to mount in a rigid configuration by pairing with another single row tapered roller bearing and applying preload. Ideal for gearboxes, machinery, and heavy-duty industrial equipment.
