  • Shield type (contact/non-contact)

Technical Specifications

Load capacity comparison of anti-friction bearings

When calculating dynamic load ratings, use formula C = P√(L/1,000,000) where L represents revolutions. Major manufacturers like SKF require minimum hardness of 58 HRC on raceways.

Market Trends

Southern states show 22% higher demand for agricultural bearings (U.S. Department of Commerce). New EPA regulations mandate <0.1% chlorinated paraffin in lubricants by Q3 2024.

FAQ

Q: Do ceramic bearings suit food processing plants?
