7022 CDTP/HCP4B Bearing Product Overview & Core Advantages
The 7022 CDTP/HCP4B is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. This single-row bearing is distinguished by its P4 (ABEC-7) tolerance class, ensuring minimal runout and superior performance. Its 15° contact angle is optimized to handle significant combined loads—simultaneous radial and axial forces—making it an ideal solution for high-speed spindles and precision machinery. The bearing comes preloaded and lubricated from the factory, guaranteeing immediate operational readiness and consistent performance.

| 7022 | Standard bearing series designation, indicating a 110mm bore, 170mm OD, and 28mm width. |
| C | Specifies a 15° contact angle. |
| DTP | Indicates a duplex arrangement (face-to-face, back-to-back, or tandem) with a specific preload. |
| HCP4B | Denotes a hybrid ceramic bearing with P4 precision class and specific internal design for high-speed operation. |
7022 CDTP/HCP4B Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The combination of chrome steel rings and ceramic balls significantly reduces weight and centrifugal forces, enabling higher limiting speeds (9,500 rpm) and providing superior resistance to wear and thermal stress.
- High Rigidity & Precision: Manufactured to P4 tolerance class with a phenolic resin cage, this bearing offers exceptional dimensional stability and minimal vibration, which is critical for high-precision applications.
- Optimized Load Capacity: The 15° contact angle and robust design provide a high dynamic load rating of 24,975 lbf and static load rating of 24,300 lbf, making it capable of handling demanding combined loads.
- Factory Preload & Lubrication: Supplied with a pre-applied lubricant and preloaded, the bearing ensures immediate, maintenance-free operation with consistent performance across its specified temperature range of -30° to 110°C.
7022 CDTP/HCP4B Bearing Typical Application Areas
