7206 CD/HCP4ADGB Bearing Product Overview & Core Advantages
The 7206 CD/HCP4ADGB is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and performance. This universal matchable (SU) bearing features a light preload (Class B) and is capable of handling combined radial and axial loads simultaneously. Manufactured with ceramic balls and a phenolic cage, it delivers superior high-speed performance with a limiting speed of 100,500 rpm and operates within a wide temperature range of -30°C to 110°C. Its P4A tolerance class ensures ultra-precise running accuracy, making it ideal for high-rigidity applications where minimal deflection is critical.
7206 CD/HCP4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CD | Indicates a universal matchable bearing designed for duplex mounting (DB/DF/DT) with a specific contact angle and preload. |
| HC | Signifies the use of hybrid ceramic balls (silicon nitride), offering reduced weight, lower friction, and enhanced speed capability. |
| P4A | Denotes an ultra-precision tolerance class exceeding ABEC 7/ISO P4 standards, ensuring extremely tight dimensional and running accuracy. |
| DGB | Specifies a light preload (Class B) applied to the bearing, optimizing rigidity and rotational accuracy for high-speed operation. |
7206 CD/HCP4ADGB Bearing Structural Features & Performance Benefits
Hybrid Ceramic Construction: The combination of chrome steel rings and ceramic balls significantly reduces centrifugal forces, lowers operating temperature, and extends service life, particularly in high-speed applications.
Phenolic Cage Design: The lightweight phenolic resin cage provides excellent dimensional stability and low friction at high rotational speeds, contributing to the bearing's impressive 100,500 rpm limiting speed.
Universal Matchability (SU): This bearing is universally matchable, allowing for flexible mounting arrangements (back-to-back, face-to-face, or tandem) without the need for selective assembly, simplifying installation and ensuring optimal preload.
High Rigidity & Load Capacity: The 15° contact angle and light preload provide high system rigidity, enabling the bearing to handle significant combined loads (radial and axial) with minimal deformation.
Precision Engineering: Manufactured to P4A tolerance class, this bearing guarantees ultra-precise running accuracy, low noise, and minimal vibration for critical applications.
