7022 ACE/P4A Bearing Product Overview & Core Advantages
The 7022 ACE/P4A is a single-row angular contact ball bearing designed for applications requiring high precision and high-speed operation. Engineered to a P4 (ABEC-7) tolerance class, it offers exceptional dimensional accuracy and running precision. Its primary function is to accommodate combined loads, specifically heavy radial loads and substantial axial loads in one direction. The bearing is preloaded, ensuring high system rigidity, minimal axial play, and precise shaft positioning, making it an ideal choice for high-performance machinery where accuracy and reliability are paramount.
7022 ACE/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 7022 | Basic bearing designation indicating a metric, single-row angular contact ball bearing with a 110 mm bore and 170 mm outside diameter. |
| ACE | Designates a 25° contact angle and is typically associated with a specific internal design optimized for high axial load capacity. |
| P4A | Indicates the bearing is manufactured to a P4 tolerance class (ABEC-7), signifying very high precision in dimensions and running accuracy. |
7022 ACE/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The combination of a 25° contact angle and preload provides high axial and radial stiffness, critical for applications requiring precise shaft control and minimal deflection under load.
- Superior Load Capacity: Engineered to support significant combined radial and axial loads simultaneously, making it suitable for demanding applications.
- Optimized High-Speed Performance: The lightweight and robust phenolic resin cage ensures stable operation and low friction at high rotational speeds, contributing to the bearing's limiting speed of 15,500 rpm.
- Premium Material Construction: Manufactured from chrome steel for both rings and balls, ensuring high durability, wear resistance, and a long operational life.
- Pre-Lubricated for Immediate Use: The bearing comes lubricated and is suitable for a temperature range of -30°C to 110°C.
