S7013 ACD/P4ADGC Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double-row angular contact design with 25° contact angle provides exceptional stiffness, enabling the bearing to handle significant combined radial and axial loads in both directions. With a radial dynamic load rating of 14,332 lbf and static load rating of 15,975 lbf, it offers reliable performance under demanding conditions.
Precision Performance: Manufactured to P4A tolerance standards with tight dimensional tolerances (bore: -0.004mm to 0, OD: -0.004mm to 0), this bearing ensures minimal runout and vibration for precision applications.
High-Speed Capability: The phenolic cage material and optimized internal geometry contribute to excellent high-speed performance, with a limiting speed of 31,000 rpm, making it suitable for high-speed spindle applications.
Maintenance-Free Operation: The sealed construction with factory-applied grease lubrication provides long-term protection against contamination and eliminates the need for relubrication within the operating temperature range of -30°C to 110°C.
