7022 CD/P4ATBTB Bearing Product Overview & Core Advantages
The 7022 CD/P4ATBTB is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. This triplex back-to-back (TBT) matched set delivers superior performance under combined loads, handling significant radial and axial forces simultaneously. Manufactured to P4A tolerance class with a light preload (Class B), it ensures smooth, stable operation in high-speed and high-rigidity scenarios. Its open design, pre-lubricated for immediate use, offers outstanding performance within a specified temperature range.
7022 CD/P4ATBTB Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7022 | Basic bearing designation; 110 mm bore, 170 mm OD, 84 mm width. |
| CD | Specifies a 15° contact angle and specific internal design for optimized load distribution. |
| P4A | Indicates a high-precision tolerance class with enhanced dimensional and running accuracy. |
| TBT | Denotes a Triplex Back-to-Back matched arrangement of three bearings, providing maximum rigidity and moment load capacity. |
7022 CD/P4ATBTB Bearing Structural Features & Performance Benefits
- Exceptional Rigidity & Load Capacity: The triplex back-to-back (TBT) arrangement creates an extremely rigid bearing system capable of withstanding heavy combined radial and axial loads as well as significant moment loads. This configuration is ideal for applications where shaft deflection must be minimized.
- High-Speed Capability: The phenolic cage offers low weight and excellent performance at high rotational speeds, contributing to the bearing's limiting speed of 10,000 rpm. The 15° contact angle is well-suited for high-speed operation.
- Precision Performance: Manufactured to P4A tolerance class with a light preload (Class B), this set ensures minimal runout, reduced vibration, and precise rotational accuracy critical for high-performance machinery.
- Durable Construction: Made from chrome steel for both rings and balls, the bearing provides high fatigue life and wear resistance. The open design allows for customized lubrication regimes.
7022 CD/P4ATBTB Bearing Typical Application Areas
This precision bearing set is engineered for high-performance applications, including:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers requiring extreme rigidity and accuracy.
- Precision Gearboxes: Applications demanding high rotational precision and load capacity.
- High-Frequency Motors and Spindles: Where minimal runout and stable operation at high RPM are critical.
- Industrial Pumps and Compressors: For shafts subjected to significant combined loads.
