7200 ACDGB/HCP4A Bearing Product Overview & Core Advantages
The 7200 ACDGB/HCP4A is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. This single bearing is part of a universally matchable (SU) set, allowing for precise axial preload control when mounted with a second, identical bearing. Its core advantages include the ability to handle combined loads (radial and axial) simultaneously, superior high-speed performance enabled by its phenolic cage and ceramic balls, and outstanding operational reliability due to its P4A tolerance class and light preload (Class B). This configuration makes it ideal for applications where high rigidity and minimal runout are critical.
7200 ACDGB/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
- 7200: Basic series number, indicating a 10mm bore, 30mm OD, 9mm width bearing.
- AC: Angular Contact design with a 25° contact angle.
- D: Signifies a light preload (Class B).
- GB: Indicates the bearing is Universal Matchable (SU) for paired mounting.
- /HC: Denotes the use of Hybrid Ceramic balls (ceramic balls with steel rings).
- P4A: Specifies the tolerance class, representing superior dimensional and running accuracy beyond ABEC 7.
7200 ACDGB/HCP4A Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The combination of chrome steel rings and ceramic balls significantly reduces friction, heat generation, and wear. This extends bearing life and enables higher limiting speeds compared to all-steel equivalents.
- Phenolic Cage: The lightweight and robust phenolic resin cage contributes to excellent high-speed performance and smooth operation with minimal centrifugal forces.
- High Rigidity & Load Capacity: The 25° contact angle and optimized internal geometry provide high resistance to axial loads while maintaining good radial load capacity, resulting in a robust solution for combined loads.
- Precision Engineering: Manufactured to P4A tolerance class, this bearing ensures minimal vibration and precise shaft positioning, which is crucial for high-accuracy machinery.
- Universal Matchability: As a Universal Matchable (SU) bearing, it can be paired with another identical bearing to create a preloaded set, simplifying assembly and ensuring optimal performance.
