7022 CE/P4AQBCA Bearing Product Overview & Core Advantages
The 7022 CE/P4AQBCA is a precision quadruplex matched bearing set designed for applications requiring exceptional rotational accuracy and rigidity. This metric angular contact ball bearing features an Extra Light (Class A) preload and is arranged in a Back-to-Back (QBC) configuration, enabling it to handle combined radial and axial loads simultaneously. Its P4A tolerance class ensures ultra-precise running, making it ideal for high-speed, high-rigidity spindles and other demanding precision machinery.
7022 CE/P4AQBCA Bearing Model Code Explained, Specifications & Naming Convention
The model number 7022 CE/P4AQBCA is decoded as follows:
- 7022: Basic bearing designation indicating a 110 mm bore, 170 mm OD, and 28 mm width.
- C: Denotes a 15° contact angle, optimized for high-speed operation and axial load capacity.
- E: Indicates optimized internal geometry (e.g., ball size, raceway curvature) for enhanced performance.
- P4A: Specifies the tolerance class, representing very high precision for bore diameter, outside diameter, and width.
- QBC: Signifies the bearing is part of a Quadruplex (4-bearing) set in a Back-to-Back arrangement.
- A: Denotes Extra Light preload within the matched set, minimizing friction at high speeds.
7022 CE/P4AQBCA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The quadruplex back-to-back arrangement creates an extremely rigid bearing system capable of supporting significant combined loads and moments. The 15° contact angle provides excellent axial load carrying capacity.
- Precision & High-Speed Performance: Manufactured to P4A tolerance class with an Extra Light preload, this bearing set ensures minimal runout and vibration, enabling smooth operation at its limiting speed of 10,000 rpm. The phenolic cage contributes to low friction and high-speed capability.
- Optimized Internal Design: The "E" suffix indicates enhanced internal geometry, including optimized ball diameter (12.7 mm) and ball quantity (30), which improves load distribution and overall performance.
- Durability & Reliability: Constructed from chrome steel for both rings and balls, this bearing offers high fatigue resistance and long service life in demanding applications.
7022 CE/P4AQBCA Bearing Typical Application Areas
This high-precision quadruplex bearing set is ideally suited for:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers requiring maximum rigidity and accuracy.
- Precision Gearboxes: Applications where precise shaft positioning and high load capacity are critical.
- High-Frequency Motors & Spindles: Used in applications demanding minimal vibration at very high rotational speeds.
- Industrial Robotics: Precision joints and arms requiring high moment stiffness and rotational accuracy.
