Detailed information

Deep groove ball bearings for high temperature applications with shields on both sides

Single row deep groove ball bearings for high temperature applications are shielded on both sides and are designed for severe operating conditions, with some types capable of withstanding temperatures up to 350 °C. They have a larger radial internal clearance and use a graphite-based lubricant that can operate at high temperatures. They are lubricated for life and the entire surface of the bearing is treated with manganese phosphate, which enhances the adhesion between the lubricant and the metal and improves the running-in properties. Due to their wide range of applications, deep groove ball bearings are highly versatile, can accommodate axial and radial loads in both directions, and are easy to install.

Optimized for high temperature operation - up to 350 °C 

Easy to interchange with grease-lubricated bearings of corresponding ISO sizes

Increased reliability, reduced complexity and reduced environmental impact

Inserted seals extend bearing life
