SB140XP0 Bearing Structural Features & Performance Benefits
Four-Point Contact Design: The optimized raceway geometry creates four contact points between balls and raceways, enabling the bearing to handle combined radial and axial loads efficiently while maintaining minimal cross-section dimensions.
High Load Capacity: With radial dynamic load rating of 2234 lbf and axial dynamic load rating of 3840 lbf, this bearing delivers exceptional performance in demanding applications. The static load moment rating of 41580 lbf ensures reliable operation under heavy static conditions.
Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional control (bore and OD tolerance: -0.0014" to 0"), ensuring consistent performance and easy installation.
Corrosion Resistance: Constructed entirely from stainless steel components with a brass cage, providing excellent corrosion resistance and making it suitable for harsh environments and cleanroom applications.
Temperature Performance: Operates reliably across a wide temperature range from -30°C to 110°C, maintaining dimensional stability and lubrication effectiveness.
