SKF 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
