S7024 CD/P4ADBA Bearing Structural Features & Performance Benefits
Enhanced Rigidity: The duplex back-to-back arrangement creates a rigid bearing system that effectively resists moment loads, providing exceptional stability under complex loading conditions.
Superior Load Capacity: With a 15° contact angle and optimized internal geometry, this bearing efficiently handles combined radial and axial loads in both directions, featuring a dynamic load rating of 42,750 lbf and static load rating of 55,125 lbf.
High-Speed Capability: The phenolic resin cage ensures smooth operation at limiting speeds up to 10,000 rpm, while the extra light preload minimizes heat generation and power consumption.
Precision Performance: Manufactured to P4A tolerance standards with tight dimensional controls (bore: -0.004mm to 0, OD: -0.004mm to 0), this bearing delivers exceptional running accuracy and minimal vibration.
Sealed & Lubricated: The sealed design with factory-applied grease lubrication provides reliable operation across a temperature range of -30°C to 110°C, ensuring long service life with minimal maintenance.
