7014 CDGC/P4A Bearing Product Overview & Core Advantages
The 7014 CDGC/P4A is a single row angular contact ball bearing designed for high-precision applications requiring exceptional rotational accuracy and rigidity. Manufactured to P4A tolerance class, this bearing delivers superior running accuracy and dimensional stability. Its 15° contact angle is optimized to handle significant combined loads (simultaneous radial and axial loads) in one direction. The phenolic cage and universal matching designation (SU) enable high-speed operation and simplified mounting in preloaded duplex arrangements, making it ideal for machine tool spindles and other precision machinery.
7014 CDGC/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CD | A 15° contact angle, optimized for high-speed performance and moderate axial load capacity. |
| GC | Indicates a Moderate Preload (Class C). This preload eliminates internal clearance, increasing system rigidity and improving rotational accuracy. |
| P4A | Denotes an ABEC 7 / ISO P4 tolerance class with additional running accuracy requirements, ensuring minimal vibration and superior performance in precision applications. |
7014 CDGC/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The P4A tolerance class guarantees tight dimensional control and exceptional running accuracy, which is critical for applications like machine tool spindles. The moderate preload (GC) further enhances system stiffness by removing internal clearance.
- Optimized Load Capacity: The 15° contact angle (CD) allows the bearing to efficiently support combined radial and axial loads. With a dynamic load rating of 11700 lbf and a static load rating of 10238 lbf, it offers reliable performance under demanding conditions.
- High-Speed Capability: The lightweight phenolic resin cage provides excellent strength and guidance at high speeds, contributing to a limiting speed of 22,000 rpm. This cage material also offers favorable performance in lubricated environments.
- Universal Matching Design: As a Universal Matchable (SU) bearing, the 7014 CDGC/P4A can be universally paired with another identical bearing to create a preloaded duplex set (DB, DF, or DT), simplifying procurement and assembly for complex arrangements.
7014 CDGC/P4A Bearing Typical Application Areas
This precision angular contact bearing is engineered for high-performance machinery, including:
- Machine Tool Spindles (milling, grinding, and lathe spindles)
- High-Frequency Motors and Spindles
- Precision Gearboxes
- Industrial Pumps and Compressors
- Robotic Arms and Precision Positioning Systems
