3205 A Bearing Product Overview & Core Advantages
The 3205 A is a metric double row angular contact ball bearing engineered for applications requiring high precision and reliability. Its design enables it to simultaneously handle combined loads—significant radial loads and bidirectional axial loads. Featuring a P6 (ABEC-3) tolerance class, this bearing offers exceptional running accuracy. The open design, combined with stainless steel cage and premium lubrication, ensures optimal performance in demanding environments, making it ideal for high-rigidity and high-speed applications.
3205 A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 3205 | Basic bearing designation indicating a Double Row Angular Contact Ball Bearing with a 25 mm bore diameter. |
| A | Signifies a 30° contact angle, optimized for carrying higher axial loads. |
3205 A Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior rigidity and enables the bearing to support substantial combined radial and axial loads from both directions. The optimized 30° contact angle (A-designation) further enhances axial load carrying capability.
High-Speed Performance: The lightweight, durable stainless steel cage minimizes centrifugal forces, contributing to a high limiting speed of 12,000 rpm. Pre-lubrication ensures smooth operation at these elevated speeds.
Precision & Longevity: Manufactured to a P6 tolerance class (equivalent to ABEC-3), this bearing guarantees high running accuracy and low noise. The use of chrome steel for rings and balls ensures high durability and wear resistance.
3205 A Bearing Typical Application Areas
This precision bearing is suited for a wide range of industrial machinery and equipment, including:
- Machine Tool Spindles
- Industrial Pumps and Compressors
- Precision Gearboxes
- Agricultural Machinery
- Material Handling Systems
