7017 CD/P4AQBCC Bearing Product Overview & Core Advantages
The 7017 CD/P4AQBCC is a precision quadruplex matched angular contact ball bearing designed for applications requiring exceptional rigidity and accuracy. This metric bearing features a back-to-back (QBC) arrangement of four bearings, enabling it to withstand combined radial and axial loads from multiple directions simultaneously. Manufactured to P4A tolerance class with a moderate preload (Class C), it delivers high running accuracy, excellent rotational stability, and superior system rigidity, making it ideal for high-precision, high-reliability machinery.

| Code Segment | Technical Meaning |
|---|---|
| 7017 | Basic bearing series, indicating a bore diameter of 85 mm and an outside diameter of 130 mm. |
| CD | Specifies a 15° contact angle and optimized internal geometry for high-precision applications. |
| P4A | Indicates a high-precision tolerance class with enhanced dimensional and running accuracy. |
| QBCC | Denotes a Quadruplex Back-to-Back (QBC) matched set with moderate preload (Class C) applied. |
7017 CD/P4AQBCC Bearing Structural Features & Performance Benefits
- Exceptional Rigidity & Load Capacity: The quadruplex back-to-back arrangement creates an extremely rigid bearing system capable of handling heavy combined loads and complex moment loads, ensuring minimal shaft deflection under operation.
- High-Precision Performance: Manufactured to P4A tolerance standards with a 15° contact angle, this bearing provides superior running accuracy and smooth, low-vibration operation essential for precision machinery.
- Optimized High-Speed Capability: The phenolic cage offers low weight and excellent performance at high speeds, contributing to the bearing's limiting speed of 28,000 rpm.
- Preloaded & Ready-to-Install: The set is supplied with a moderate preload (Class C), eliminating the need for complex on-site adjustment and ensuring immediate, optimal performance upon installation.
- Premium Material Construction: Made from chrome steel for both rings and balls, the bearing ensures high durability, long service life, and consistent performance within a temperature range of -30°C to 110°C.
