7022 CD/P4ATBTA Bearing Product Overview & Core Advantages
The 7022 CD/P4ATBTA is a precision angular contact ball bearing designed for applications demanding exceptional rigidity and running accuracy. This triplex back-to-back (TBT) matched set consists of three individual bearings, enabling it to withstand heavy combined loads (radial and axial) from multiple directions simultaneously. Manufactured to P4A tolerance class, it offers superior dimensional and running accuracy, making it ideal for high-speed, high-precision spindles and other critical machinery components. The extra light preload (Class A) ensures minimal deflection and optimal performance under operational conditions.
7022 CD/P4ATBTA Bearing Model Code Explained, Specifications & Naming Convention
- 7022: Basic bearing designation (Bore: 110 mm, OD: 170 mm, Width: 84 mm)
- C: 15° contact angle
- D: Indicates a specific internal design optimization
- P4A: Tolerance class denoting very high precision levels for both dimension and running accuracy
- TB: Back-to-Back mounting arrangement
- T: Triplex set (three bearings in a matched set)
- A: Extra light preload (Class A)
7022 CD/P4ATBTA Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The triplex back-to-back configuration creates an extremely rigid bearing system, capable of handling significant radial dynamic load ratings of 53,550 lbf and radial static load ratings of 73,125 lbf. This arrangement is exceptionally effective at resisting moment loads and complex combined loads.
Precision & Speed Performance: Built to P4A tolerance class with a 15° contact angle, this bearing ensures minimal runout and vibration. The phenolic cage and optimized internal geometry contribute to a high limiting speed of 10,000 rpm, suitable for demanding high-speed applications.
Material & Construction: Components are manufactured from high-grade chrome steel for both rings and balls, ensuring durability and long service life under heavy loads. The open seal type allows for customized lubrication schemes to match specific operational requirements.
