7014 CD/P4AQBCC Bearing Product Overview & Core Advantages
The 7014 CD/P4AQBCC is a precision quadruplex back-to-back angular contact ball bearing designed for applications requiring exceptional rigidity and accuracy. This P4A tolerance class bearing features a moderate preload (Class C), making it ideal for handling combined loads with high stability. Its matched set of four bearings provides superior stiffness and rotational precision, while the phenolic cage enables reliable high-speed performance up to 22,000 rpm. This configuration is engineered for demanding machinery where uncompromising precision and rigid support are critical.

7014 CD/P4AQBCC Bearing Structural Features & Performance Benefits
Optimized Bearing Geometry: The 15° contact angle and precision-ground raceways ensure optimal load distribution and smooth operation under combined radial and axial loads.
Superior Rigidity: The quadruplex back-to-back arrangement creates an extremely rigid bearing system that minimizes deflection under heavy loads and moment forces, essential for maintaining precision in demanding applications.
High-Speed Capability: The phenolic resin cage provides excellent strength-to-weight ratio, reducing centrifugal forces and enabling reliable operation at limiting speeds of 22,000 rpm.
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional controls (bore/OD tolerance: -0.004mm to 0), ensuring consistent performance and interchangeability.
Robust Construction: Chrome steel rings and balls with 19 balls of 12.7mm diameter provide high dynamic load capacity (30,375 lbf) and static load capacity (41,175 lbf) for long service life.
