7220 BECBM Bearing Product Overview & Core Advantages
The 7220 BECBM is a single row angular contact ball bearing engineered for high-precision applications requiring superior performance under combined loads. This metric bearing is characterized by its 40° contact angle, which enables it to efficiently support significant axial loads in one direction alongside radial loads. Manufactured to P6 (ABEC-3) tolerance class, it guarantees exceptional running accuracy and rotational stability. Its open design allows for versatile lubrication options, making it ideal for high-speed machinery where reliability and precision are paramount.

| Suffix | Technical Meaning |
|---|---|
| BE | Designates an increased 40° contact angle for high axial load capacity. |
| CBM | Indicates the bearing is supplied lubricated and ready for operation. |
7220 BECBM Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row design with a 40° contact angle and optimized internal geometry provides excellent rigidity, enabling the bearing to handle substantial combined radial and axial loads.
- Precision & High-Speed Performance: Built to a P6 tolerance class, it ensures minimal vibration and high running accuracy. The brass cage contributes to stability and allows for a high limiting speed of 5,600 rpm.
- Optimized for Performance: The calculated distance from side face to load point (76 mm) ensures optimal load distribution and moment load capacity. The chrome steel construction provides high durability and fatigue resistance.
- Operational Readiness: The bearing is supplied lubricated and is suitable for a temperature range of -30°C to 110°C, offering immediate installation and reliable performance.
