7213 ACDGA/P4A Bearing Product Overview & Core Advantages
The 7213 ACDGA/P4A is a high-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a single-row bearing with a 25° contact angle, it excels at supporting combined loads, particularly high axial loads in one direction. Manufactured to the stringent P4A tolerance class, it offers superior dimensional and running accuracy, making it ideal for high-speed spindles and other precision machinery where minimal runout and vibration are critical. Its universal matchable (SU) design allows for flexible mounting in various preload configurations.

|---|---|
| 7213 | Basic bearing series; 65 mm bore, 120 mm OD, 23 mm width. |
| AC | Angular Contact design with a 25° contact angle. |
| DGA | Specific internal design and cage type (Phenolic). |
| P4A | Ultra-precision tolerance class for high running accuracy and low vibration. |
7213 ACDGA/P4A Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: The P4A tolerance class ensures extremely tight dimensional control on bore, outer diameter, and width, resulting in superior system rigidity and precise shaft positioning.
- Optimized Load Capacity: The 25° contact angle is engineered to handle significant axial loads in one direction while also supporting substantial radial loads, making it suitable for combined loading scenarios.
- High-Speed Capability: The lightweight and robust phenolic cage provides excellent guidance for the balls, contributing to stable operation and a high limiting speed of 32,500 rpm.
- Pre-Configured Performance: The bearing is supplied lubricated and is universally matchable (SU), allowing for simplified installation and optimal performance when mounted in pairs or sets to achieve specific preload (Extra light / Class A).
7213 ACDGA/P4A Bearing Typical Application Areas
This bearing is specified for high-performance applications where precision and speed are paramount. Key industries and equipment include:
- Machine Tool Spindles: For CNC milling, grinding, and turning centers.
- High-Speed Motors and Spindles: Used in PCB drilling, dental handpieces, and small precision spindles.
- Precision Robotic Drives: In joints and actuators requiring high accuracy and responsiveness.
- Aerospace and Defense Systems: In gyroscopes, navigation instruments, and other critical control mechanisms.
