S7016 ACD/P4AQBCC Bearing Structural Features & Performance Benefits
Quadruplex Back-to-Back Configuration: Four bearings arranged in back-to-back pairs create an extremely rigid bearing system that resists moment loads and shaft deflection, making it ideal for applications requiring maximum stability.
Enhanced Load Capacity: With a radial dynamic load rating of 37,125 lbf and radial static load rating of 52,200 lbf, this bearing system handles substantial combined radial and axial loads simultaneously, providing reliable performance under demanding conditions.
High-Speed Capability: The phenolic cage material and optimized internal geometry enable a limiting speed of 28,000 rpm, supporting high-speed operation while maintaining dimensional stability and precision.
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional controls (bore/OD tolerance: -0.004mm to 0), ensuring consistent performance and interchangeability in precision assemblies.
Sealed & Lubricated Design: The sealed construction with factory-applied grease lubrication provides contamination protection and extends service intervals, suitable for operating temperatures from -30°C to 110°C.
