7022 CD/P4AQBCA Bearing Product Overview & Core Advantages
The 7022 CD/P4AQBCA is a precision quadruplex angular contact ball bearing designed for applications requiring exceptional rigidity and load capacity. This P4A tolerance class bearing features a back-to-back quadruplex arrangement, enabling it to handle significant combined loads (radial and axial) from multiple directions simultaneously. Its extra light preload and 15° contact angle ensure high running accuracy and stability, making it ideal for ultra-precision, high-stiffness machinery.
7022 CD/P4AQBCA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| CD | 15° contact angle, high-precision design | Optimized for combined radial and axial loads |
| P4A | Super precision tolerance class (ABEC 7 equivalent) | Exceptional running accuracy and minimal vibration |
| QBC | Quadruplex Back-to-Back arrangement | Maximum system rigidity and moment load capacity |
| A | Extra light preload | Reduced friction, suitable for high-speed applications |
7022 CD/P4AQBCA Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The quadruplex back-to-back configuration creates an extremely rigid bearing system capable of withstanding heavy combined loads and moment loads. With a radial dynamic load rating of 65,475 lbf and static load rating of 99,000 lbf, this bearing delivers exceptional performance in demanding applications.
Precision Performance: Manufactured to P4A tolerance class standards with chrome steel rings and balls, the bearing ensures minimal runout and vibration. The phenolic cage provides excellent dimensional stability and reduced weight, contributing to smoother operation at the limiting speed of 10,000 rpm.
Optimized Design: The 15° contact angle and extra light preload balance axial and radial load capacity while minimizing friction and heat generation. The open design allows for customized lubrication schemes to match specific application requirements.
