Product introduct
21320CCSpherical roller bearings are dedicated to extremely severe applications and must support high loads, severe misalignment, contaminated environments, shocks, and vibrations. sphericals feature the industry’s highest load rating(Factory price, high quality)
a full 18% higher than a standard spherical roller bearing. This level of quality means at least a 75% extension of service life. The performance of these sphericals is achieved through the use of very high quality raw materials and optimized rolling element geometry.
The unique design also leads to: Reduced friction torque (as much as 30% less), offering lower operating temperature, with lower power and lubricant consumption.
