7022 ACDTP/HCP4B Bearing Product Overview & Core Advantages
The 7022 ACDTP/HCP4B is a single-row angular contact ball bearing engineered for applications demanding ultra-high precision and exceptional speed performance. Its defining characteristic is the 25° contact angle, optimized to support significant combined radial and axial loads in one direction. Manufactured to the stringent P4 (ABEC-7) tolerance class and featuring a phenolic cage with ceramic balls, this bearing is the ideal solution for high-rigidity, high-speed spindle systems requiring maximum rotational accuracy and thermal stability.
7022 ACDTP/HCP4B Bearing Model Code Explained, Specifications & Naming Convention
- 7022: Basic designation indicating a metric series bearing with a 110 mm bore and 170 mm outside diameter.
- AC: Angular Contact design with a defined contact angle to handle combined loads.
- DTP: Signifies a duplex (matched) pair configuration. While the specification states "Matched arrangement: Single," this suffix indicates it is supplied as a pre-set pair for preload and increased system rigidity.
- HC: Denotes the use of Hybrid Ceramic components, specifically ceramic balls.
- P4B: Indicates a P4 tolerance class with enhanced running accuracy specifications, suitable for the most demanding precision applications.
7022 ACDTP/HCP4B Bearing Structural Features & Performance Benefits
High-Speed & Thermal Performance: The combination of a lightweight phenolic cage and low-density, hard ceramic balls significantly reduces centrifugal forces, enabling the high limiting speed of 8,500 rpm. Hybrid construction also minimizes heat generation and provides superior performance across the specified temperature range.
High Rigidity & Load Capacity: The bearing is designed to be used in a duplex pair (DTP) with preload. This arrangement dramatically increases system stiffness, minimizes axial and radial deflection under load, and ensures precise positioning. The 25° contact angle provides excellent axial load carrying capacity.
Ultra-Precision: Manufactured to P4 tolerance standards, this bearing guarantees extremely tight dimensional and running accuracy, resulting in superior performance in precision machinery.
Long-Term Reliability: The bearing comes lubricated from the factory. The open seal type allows for optimal lubrication management in controlled environments, which is critical for maintaining performance at high speeds.
