Bearing
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.
