Product Overview: The 21310 Spherical Roller Bearing
The 21310 bearing is a high-performance spherical roller bearing, an integral part of our robust 21300 Series Spherical Roller Bearings. With its specific dimensions of 50mm bore diameter, 110mm outer diameter, and 27mm thickness, this bearing is engineered to deliver exceptional reliability and efficiency in demanding industrial environments. Spherical roller bearings like the 21310 are renowned for their ability to accommodate significant radial and axial loads, as well as handle misalignment, making them indispensable components in heavy machinery applications.
Designed with two rows of rollers and a common spherical raceway in the outer ring, the 21310 bearing's self-aligning capability allows it to compensate for angular misalignment between the shaft and the housing, which can arise from manufacturing errors, mounting inaccuracies, or shaft deflection under load. This inherent adaptability ensures consistent performance and extended service life, even in conditions where precise alignment is challenging to maintain. Our commitment as a leading supplier of industrial bearings ensures that the 21310 bearing meets rigorous industry standards for durability and performance.
Features of the 21310 Bearing
- High Load Capacity: Engineered to withstand very heavy radial loads and significant axial loads in both directions, ideal for demanding applications.
- Self-Aligning Capability: Automatically compensates for angular misalignment of the shaft relative to the housing, reducing stress and preventing premature wear.
- Robust Construction: Designed for durability and long service life, even in harsh operating conditions.
- Low Friction Operation: Optimized internal geometry ensures smooth rotation, minimizes heat generation, and improves energy efficiency.
- Vibration Resistance: Capable of performing reliably in applications subject to high levels of vibration.
