7013 CD/HCP4AQBCA Bearing Product Overview & Core Advantages
The 7013 CD/HCP4AQBCA is a high-precision quadruplex angular contact ball bearing designed for applications demanding exceptional rigidity and accuracy. This metric system bearing features a back-to-back (QBC) matched arrangement of four bearings, enabling it to support combined loads (radial and axial) simultaneously with high stability. Its P4A tolerance class and ceramic ball construction make it ideal for high-speed operation and high-reliability scenarios where minimal runout and precise rotation are critical.
7013 CD/HCP4AQBCA Bearing Model Code Explained, Specifications & Naming Convention
The model number 7013 CD/HCP4AQBCA is decoded as follows:
- 7013: Basic series designation, indicating a bore diameter of 65 mm.
- CD: Indicates a 15° contact angle, optimized for high-speed performance.
- HC: Signifies the use of Hybrid Ceramic balls (Silicon Nitride).
- P4A: Denotes an ultra-precision tolerance class with enhanced running accuracy.
- QBC: Stands for Quadruplex Back-to-Back matched arrangement, providing high rigidity and moment load capacity.
- A: Indicates Extra Light Preload for minimal friction and optimal high-speed performance.
7013 CD/HCP4AQBCA Bearing Structural Features & Performance Benefits
- Exceptional Rigidity and Load Capacity: The quadruplex back-to-back (QBC) arrangement creates a highly rigid bearing system capable of withstanding significant combined radial and axial loads and moment loads, making it suitable for demanding machinery.
- Superior High-Speed Performance: The combination of hybrid ceramic balls (reducing centrifugal force and heat generation) and a lightweight phenolic resin cage allows for a high limiting speed of 36,000 rpm. The 15° contact angle further enhances high-speed suitability.
- Ultra-Precision Operation: Manufactured to P4A tolerance class, this bearing ensures extremely tight dimensional control (bore and OD tolerance: -0.004mm to 0) for applications requiring the highest levels of running accuracy and minimal vibration.
- Optimized for Pre-Lubrication: Comes lubricated from the factory, ready for immediate installation and operation within its specified temperature range.
7013 CD/HCP4AQBCA Bearing Typical Application Areas
This high-precision bearing is ideally suited for:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Robotics: Arm joints and rotary actuators requiring high rigidity and accuracy.
- Aerospace & Defense Systems: Gyroscopes, radar systems, and other critical navigation equipment.
- High-Frequency Motors and Spindles: Where minimal friction and heat generation are paramount.
