21314 E/C3

The 21314 E/C3 is a heavy-duty spherical roller bearing engineered to excel in environments where shaft misalignment or housing deflection is a constant challenge. Featuring a 70mm bore, 150mm outside diameter, and a 35mm width, this model incorporates the "E" design-a high-capacity internal configuration without a central fixed rib on the inner ring. By utilizing a floating guide ring and two stamped steel cages, the bearing significantly lowers internal friction while maximizing load distribution. The C3 radial internal clearance is a critical feature for high-speed or high-temperature operations, providing the necessary room for thermal expansion without compromising the structural integrity of the rolling elements.

Designed for long-term reliability in demanding sectors like mining, paper mills, and industrial gearboxes, this bearing type is inherently self-aligning. The outer ring features a common sphered raceway, allowing the double row of rollers to adjust dynamically to angular deviations. This specific 21314 E/C3 variant often includes an annular groove and three lubrication holes (W33 feature) to streamline maintenance and ensure consistent relubrication. Whether you are dealing with extreme radial loads or combined axial forces, this bearing's robust steel construction and optimized roller geometry provide the durability needed to minimize unplanned downtime and extend the service life of your rotating equipment.
