S7016 ACD/P4AQBCB Bearing Structural Features & Performance Benefits
Exceptional Rigidity: The quadruplex back-to-back configuration creates an extremely rigid bearing system that minimizes deflection under heavy loads, ensuring precise shaft positioning and reduced vibration.
Superior Load Capacity: With a 25° contact angle and optimized internal geometry, this bearing efficiently handles combined radial and axial loads in both directions, supported by impressive dynamic (37,125 lbf) and static (52,200 lbf) load ratings.
High-Speed Capability: The phenolic cage material and precision manufacturing enable reliable operation at speeds up to 28,000 rpm, while the sealed design maintains consistent lubrication.
Precision Performance: Manufactured to P4A tolerance standards with tight dimensional controls (bore tolerance: -0.004mm to 0), this bearing delivers exceptional running accuracy and minimal runout.
Maintenance-Free Operation: Pre-greased and sealed construction provides long-term lubrication retention and protection against contaminants, reducing maintenance requirements.
