7205 ACCBM Bearing Product Overview & Core Advantages
The 7205 ACCBM is a single row angular contact ball bearing designed for applications requiring high precision and reliable performance under combined loads. This precision bearing excels at simultaneously handling significant radial loads and axial loads in one direction, making it ideal for demanding arrangements. Its open design allows for optimal lubrication management, while the P6 (ABEC-3) tolerance class ensures exceptional running accuracy and dimensional stability for high-reliability applications.
7205 ACCBM Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7205 | Standard bearing series designation indicating a 25mm bore, 52mm OD, and 15mm width. |
| A | Denotes a 25° contact angle, optimized for carrying higher axial loads. |
| C | Specifies a brass cage (Cage material), providing high strength and excellent guidance at high speeds. |
| BM | Indicates the bearing is supplied lubricated and ready for installation. |
7205 ACCBM Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The optimized 25° contact angle and robust single row design provide excellent resistance to combined (radial and axial) loads, ensuring stable operation and high rigidity in the supported system.
- High-Speed Capability: The precision-machined brass cage (Cage material) ensures smooth ball guidance, reduces friction, and contributes to the high limiting speed of 26,000 rpm.
- Precision Performance: Manufactured to a P6 (ABEC-3) tolerance class with tight dimensional control on the bore diameter, outside diameter, and width, guaranteeing precise shaft positioning and minimal runout.
- Durability & Reliability: Constructed from high-grade chrome steel for both rings and balls, this bearing offers a long service life. The specified shoulder diameters ensure secure mounting and optimal load distribution.
7205 ACCBM Bearing Typical Application Areas
This angular contact ball bearing is engineered for high-performance applications, including:
- Machine Tool Spindles
- High-Speed Pumps and Compressors
- Precision Gearboxes
- Agricultural Machinery
- Material Handling Equipment
