7206 CD/P4ADT Bearing Product Overview & Core Advantages
The 7206 CD/P4ADT is a precision angular contact ball bearing supplied as a matched duplex tandem (DT) pair to a P4A tolerance class. This configuration is engineered to deliver exceptional performance in applications requiring high rigidity and the capacity to handle significant axial loads in a single direction. The preloaded tandem arrangement ensures minimal axial play, providing superior rotational accuracy and system stiffness, making it an ideal choice for high-speed spindles and other precision machinery.
7206 CD/P4ADT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7206 | Basic bearing designation (30mm bore, 62mm OD, 32mm width). |
| C | 15° contact angle, optimized for high axial load capacity. |
| D | Indicates the bearing is part of a matched set. |
| P4A | High precision tolerance class (exceeding ABEC 7), ensuring tight running accuracy. |
| DT | Duplex Tandem arrangement. Two bearings are mounted together to increase axial load capacity in one direction. |
7206 CD/P4ADT Bearing Structural Features & Performance Benefits
- High Rigidity & Axial Load Capacity: The duplex tandem (DT) arrangement combines two bearings to create a highly rigid unit capable of supporting very high axial loads in one direction, making it suitable for preloaded systems.
- Precision Performance: Manufactured to a P4A tolerance class, this bearing guarantees minimal runout and exceptional rotational accuracy for demanding applications.
- High-Speed Capability: The lightweight phenolic resin cage reduces centrifugal forces, contributing to a high limiting speed of 71,500 rpm. The 15° contact angle further enhances high-speed suitability.
- Durability and Reliability: Constructed from high-grade chrome steel for both rings and balls, the bearing offers excellent fatigue life and wear resistance.
7206 CD/P4ADT Bearing Typical Application Areas
This bearing is specifically designed for high-performance applications, including:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Drilling Heads
- High-Frequency Motors
- Other precision machinery requiring high rigidity, high speed, and superior axial load capacity.
