7010 CD/P4AQBCA Bearing Product Overview & Core Advantages
The 7010 CD/P4AQBCA is a precision quadruplex angular contact ball bearing designed for applications requiring exceptional rigidity and accuracy. This metric bearing features an Extra Light (Class A) preload and is configured in a Back-to-Back (QBC) matched arrangement, enabling it to handle significant combined loads (radial and axial) from both directions simultaneously. Its P4A tolerance class ensures superior running accuracy, making it ideal for high-speed, high-precision machinery where stability and reliability are paramount.
7010 CD/P4AQBCA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7010 | Basic bearing designation indicating a 50 mm bore, 80 mm OD, and 64 mm width. |
| CD | Indicates a 15° contact angle, optimized for high-speed operation and axial load capacity. |
| P4A | Denotes a high-precision tolerance class with enhanced dimensional and running accuracy. |
| QBC | Signifies a Quadruplex Back-to-Back arrangement of four matched bearings, providing maximum rigidity. |
7010 CD/P4AQBCA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The quadruplex back-to-back configuration creates a highly rigid bearing system capable of withstanding heavy combined radial and axial loads from any direction, minimizing shaft deflection under operation.
- Precision Performance: Manufactured to P4A tolerance standards with tight dimensional controls (bore/OD tolerance: -0.004mm to 0), ensuring smooth, quiet, and accurate rotation essential for high-speed spindles.
- Optimized High-Speed Design: The 15° contact angle and phenolic resin cage reduce friction and centrifugal forces, supporting a high limiting speed of 41,000 rpm.
- Superior Material Construction: Made from chrome steel for both rings and balls, offering high hardness, wear resistance, and durability under demanding conditions.
- Pre-lubricated & Ready-to-Install: The bearing is factory-lubricated, simplifying installation and providing immediate operational readiness within a temperature range of -30°C to 110°C.
7010 CD/P4AQBCA Bearing Typical Application Areas
This bearing is specifically engineered for high-performance applications, including:
- Machine Tool Spindles (e.g., CNC milling, grinding, and turning centers)
- High-Speed Machining Centers
- Precision Grinding Spindles
- Industrial Pumps and Compressors
