7211 ACCBM Bearing Product Overview & Core Advantages
The 7211 ACCBM is a single row angular contact ball bearing engineered for applications requiring high precision and reliable performance under combined loads. Its 25° contact angle design enables it to efficiently support significant radial loads and unidirectional axial loads simultaneously. Manufactured to a P6 (ABEC-3) tolerance class, this bearing is ideal for high-speed operations, with a limiting speed of 12,000 rpm. The open design allows for versatile lubrication options, optimizing performance across a wide temperature range from -30°C to 110°C.
7211 ACCBM Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7211 | Standard bearing series designation indicating a 55 mm bore, 100 mm OD, and 21 mm width. |
| AC | Angular Contact design with a defined contact angle (25° in this case) for combined load capacity. |
| CBM | Specific manufacturer designation for internal geometry and performance characteristics. |
7211 ACCBM Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Built to P6 tolerance (ABEC-3) with a brass cage for stable operation and precise shaft guidance, ensuring minimal runout and high system rigidity.
- Superior Load Capacity: The 25° contact angle and optimized internal geometry provide excellent radial dynamic load rating of 12,825 lbf and static load rating of 10,125 lbf, making it suitable for demanding applications with combined loads.
- Optimized High-Speed Performance: The brass cage and open design contribute to a high limiting speed of 12,000 rpm, reducing friction and heat generation during operation.
- Robust Material Construction: Made from chrome steel for both rings and balls, ensuring high durability, wear resistance, and long service life under rigorous conditions.
- Precise Mounting & Stability: Features clearly defined shoulder diameters (inner ring: 72.63 mm / 63.6 mm, outer ring: 83.19 mm) and a 28 mm distance from side face to load point for accurate positioning and enhanced operational stability.
