Spherical Roller Bearings

BS2-2209-2RS/GFP9VA944 Spherical Roller Bearings

NR Food line spherical roller bearings are compliant with food safety regulations. Designed with food grade seals and grease, they enhance food safety, increase reliability and support sustainable development. Spherical roller bearings can accommodate heavy loads in both directions. They are self-aligning and accommodate misalignment and shaft deflections, with virtually no increase in friction or temperature.

Compliant with food safety regulations
Accommodate misalignment
High load carrying capacity
Low friction and long service life
Increased wear resistance
