7010 CD/P4AQBCB Bearing Product Overview & Core Advantages
The 7010 CD/P4AQBCB is a precision quadruplex angular contact ball bearing designed for demanding applications requiring exceptional rigidity and accuracy. This P4A tolerance class bearing features a back-to-back (QBC) matched arrangement of four bearings, providing superior stiffness and the ability to handle significant combined loads (radial and axial). Its light preload (Class B) ensures optimal running accuracy and minimal deflection, making it ideal for high-precision, high-speed machinery where rotational stability is critical.

|---|---|
| 7010 | Standard bearing series designation (50mm bore, 80mm OD) |
| CD | Contact angle of 15° |
| P4A | High precision tolerance class (superior to ABEC 7) |
| QBCB | Quadruplex Back-to-Back matched arrangement with Light preload |
7010 CD/P4AQBCB Bearing Structural Features & Performance Benefits
Exceptional Rigidity: The quadruplex back-to-back configuration creates a highly rigid bearing system that effectively resists moment loads and shaft deflection, ensuring precise rotational alignment under heavy combined loads.
High-Speed Capability: The phenolic cage provides excellent strength-to-weight ratio and smooth operation at the limiting speed of 41,000 rpm, while the 15° contact angle optimizes performance for high-speed applications.
Superior Load Capacity: With a dynamic load rating of 17,550 lbf and static load rating of 21,712 lbf, this bearing set delivers reliable performance in demanding conditions where both radial and axial loads are present.
Precision Engineering: Manufactured to P4A tolerance standards with tight dimensional controls (bore/OD tolerance: -0.004mm to 0), ensuring consistent high-precision performance and interchangeability.
