S7015 CD/P4ADBA Bearing Product Overview & Core Advantages
The S7015 CD/P4ADBA is a precision duplex angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. This matched back-to-back (DB) arrangement provides superior stability and can accommodate combined radial and axial loads from both directions. Manufactured to ABEC 7 / P4A tolerance class with an extra light preload, it is engineered for high-speed operation and long-term reliability in the most demanding precision machinery.
S7015 CD/P4ADBA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7015 | Bearing series and size designation (75mm bore, 115mm OD). |
| C | 15° contact angle, optimized for high-speed applications requiring high rigidity. |
| D | Duplex bearing (two bearings supplied as a set). |
| P4A | High-precision tolerance class (equivalent to ABEC 7), ensuring minimal runout and vibration. |
| DB | Back-to-Back arrangement. This configuration provides high moment rigidity and is ideal for supporting overturning moments. |
| A | Extra light preload, which minimizes friction and heat generation, enabling higher limiting speeds. |
S7015 CD/P4ADBA Bearing Structural Features & Performance Benefits
- High Rigidity & Stability: The duplex back-to-back (DB) design creates a wide, rigid support system that effectively resists moment loads and shaft deflection, ensuring precise shaft positioning.
- Superior Load Capacity: The angular contact design and duplex arrangement allow the bearing set to handle significant combined radial and axial loads in both directions simultaneously.
- Optimized High-Speed Performance: The combination of a 15° contact angle, light preload, and a phenolic resin cage reduces centrifugal forces and friction, contributing to a high limiting speed of 28,000 rpm.
- Precision Engineering: Manufactured to P4A tolerance class with tight dimensional control on bore, outside diameter, and width, guaranteeing smooth, quiet, and accurate operation.
- Sealed & Pre-Lubricated: The sealed design with factory-applied grease lubrication protects against contamination and provides reliable operation within a temperature range of -30°C to 110°C.
S7015 CD/P4ADBA Bearing Typical Application Areas
This high-precision duplex bearing is ideally suited for applications requiring high speed, high rigidity, and exceptional accuracy, such as:
- Machine Tool Spindles (e.g., CNC machining centers, grinding spindles)
- High-Frequency Motors and Spindle Drives
- Precision Gearboxes
- Industrial Pumps and Compressors
- Robotic Arms and Rotary Tables
