7206 CD/HCP4A Bearing Product Overview & Core Advantages
The 7206 CD/HCP4A is a single-row angular contact ball bearing engineered for high-precision applications requiring exceptional rotational accuracy and speed capability. Designed to accommodate primarily axial loads in one direction, this bearing features a 15° contact angle and is supplied with a light preload, ensuring minimal deflection and high system rigidity. Manufactured to P4 (ABEC-7) tolerance class, it guarantees superior running accuracy. The combination of a ceramic ball material and a phenolic resin cage enables outstanding high-speed performance, with a limiting speed of 45,000 rpm, making it ideal for demanding spindle applications.
Model Code Breakdown
| Code Segment | Technical Meaning |

| 7206 | Basic bearing series and size designation (30mm bore, 62mm OD, 16mm width). |
| C | Designates a 15° contact angle. |
| D | Indicates the bearing is supplied with a light preload for enhanced rigidity. |
| HC | Signifies the use of Hybrid Ceramic balls (steel rings with ceramic balls). |
| P4 | Specifies the P4 tolerance class (ABEC-7), denoting very high precision. |
| A | Indicates the bearing is lubricated with high-performance grease. |
7206 CD/HCP4A Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The use of ceramic balls with steel rings significantly reduces centrifugal forces, lowers operating temperature, and extends service life, especially in high-speed applications.
- High-Speed Phenolic Cage: The lightweight and robust phenolic resin cage provides excellent dimensional stability and guidance at very high rotational speeds, contributing to the bearing's 45,000 rpm limiting speed.
- Precision & Rigidity: Manufactured to P4 tolerance class and supplied with a preload, this bearing ensures high running accuracy, minimal axial and radial play, and superior system stiffness.
- Optimized Load Capacity: The 15° contact angle is optimized to handle significant axial loads in one direction while also supporting moderate radial loads, offering a versatile load rating (Dynamic: 5445 lbf, Static: 3600 lbf).
- Wide Temperature Range: The specified materials and lubrication allow for reliable operation within a temperature range of -30°C to 110°C.
7206 CD/HCP4A Bearing Typical Application Areas
This high-precision angular contact bearing is ideally suited for applications where high speed, accuracy, and rigidity are paramount. Key industries and equipment include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Robotics: High-accuracy robotic arms and joints.
- High-Frequency Motors and Spindles: Motors for PCB drilling and dental handpieces.
- Aerospace & Defense Systems: Gyroscopes, radar systems, and navigation equipment.
- Medical Equipment: Centrifuges and high-speed dental drills.
