7014 CDGC/HCP4A Bearing Product Overview & Core Advantages
The 7014 CDGC/HCP4A is a high-precision angular contact ball bearing designed for applications demanding exceptional accuracy and rigidity. Manufactured to P4A tolerance class, this bearing excels in high-speed scenarios, supported by its ceramic ball construction and phenolic cage. Its defining characteristic is the 15° contact angle, optimized to handle combined loads—significant radial loads alongside substantial axial loads in one direction. As a Universal Matchable (SU) bearing, it is supplied in a set of two, allowing for precise preloading (Moderate / Class C) when mounted in pairs to achieve superior system stiffness and rotational accuracy, making it ideal for high-reliability, precision machinery.

| CD | Specifies a 15° contact angle. |
| GC | Indicates a Moderate preload (Class C). |
| HCP4A | Denotes the bearing is supplied as one of a Universal Matchable (SU) pair and manufactured to the high P4A tolerance class for exceptional running accuracy. |
7014 CDGC/HCP4A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design and the use of a matched pair under preload create an exceptionally high rigidity system, capable of supporting significant combined radial and axial loads.
- Superior High-Speed Performance: The combination of lightweight ceramic balls and a phenolic resin cage reduces centrifugal forces and friction, enabling a high limiting speed of 22,000 rpm. This makes it an excellent high-speed bearing solution.
- Enhanced Durability and Temperature Resistance: Ceramic balls offer superior hardness, lower thermal expansion, and electrical insulation compared to steel, enhancing bearing life in demanding conditions. The phenolic cage is stable across the specified temperature range.
- Precision Engineering: Manufactured to P4A tolerance with tight dimensional control on bore, outside diameter, and width, ensuring predictable performance and ease of installation in precision assemblies.
