7209 Hybrid Angular Contact Ball Bearings (45X85X19)
$ 218.00
7209 Hybrid Angular contact ball bearings designed for high-speed, high rigidity applications. As silicon nitride ceramic balls are considerably 40% lighter and harder than steel balls, they can run at higher speeds and lower temperature. This leads to less heat generation, less energy and longer lubricant life.
7209 Hybrid Angular Contact Spindle and Turbine Ball Bearings (45X85X19)
Special Applications: Vacuum Pumps, Turbo-molecular Pumps, Dry Pump Bearings and Aviation & Defense.
