21312 E

The 21312 E spherical roller bearing is engineered as a high-capacity solution for demanding industrial environments where shaft misalignment and heavy radial loads are constant challenges. Featuring a 60mm bore and 130mm outside diameter, this double-row bearing stands out due to its "E" design optimization, which includes a flangeless inner ring and a reinforced steel cage. These internal refinements significantly boost the dynamic load rating (approximately 217 kN), allowing it to handle extreme stress without compromising structural integrity. By maintaining lower operating temperatures even at high reference speeds of up to 4,800 r/min, the 21312 E ensures consistent rotation and reduced energy consumption in critical machinery.

Designed for seamless integration into complex systems, the 21312 E bearing is inherently self-aligning, making it the preferred choice for applications involving long shafts or housings prone to deflection. Its robust construction is complemented by an integrated relubrication feature-typically an annular groove and three lubrication holes-which simplifies routine maintenance and extends the service life in harsh, contaminated settings like mining or construction equipment. Whether you are upgrading existing gearboxes or building new vibratory machinery, this 60x130x31 mm roller bearing provides the necessary radial and axial stability to minimize unplanned downtime and optimize overall system reliability.
