7006 ACE/P4AQBCA Bearing Product Overview & Core Advantages
The 7006 ACE/P4AQBCA is a precision quadruplex angular contact ball bearing designed for applications demanding exceptional rigidity and accuracy. This P4A tolerance class bearing features a back-to-back quadruplex arrangement, providing superior stability and the ability to handle combined radial and axial loads simultaneously. Its extra light preload (Class A) ensures minimal deflection under operational stresses, making it ideal for high-precision, high-rigidity systems requiring maximum rotational accuracy.

| Code Segment | Technical Meaning |
|---|---|
| 7006 | Basic bearing series and size designation |
| ACE | 25° contact angle and standard internal clearance |
| P4A | High precision tolerance class (superior to ABEC 7) |
| QBC | Quadruplex Back-to-Back matched arrangement |
7006 ACE/P4AQBCA Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The quadruplex back-to-back configuration creates an extremely rigid bearing system capable of withstanding heavy combined loads and moment loads. The 25° contact angle optimizes axial load carrying capacity while maintaining excellent radial performance.
Precision Performance: Manufactured to P4A tolerance standards with tight dimensional controls (bore: -0.004mm to 0, OD: -0.004mm to 0), ensuring minimal runout and vibration for high-speed applications up to 71,500 rpm.
Advanced Cage Design: The phenolic resin cage provides excellent strength-to-weight ratio, reduced friction, and superior performance at high rotational speeds.
Premium Materials: Constructed from chrome steel for both rings and balls, delivering high durability, wear resistance, and consistent performance across the operating temperature range of -30°C to 110°C.
