7218 BECBM Bearing Product Overview & Core Advantages
The 7218 BECBM is a single row angular contact ball bearing engineered for high-precision applications requiring exceptional performance under combined loads. This precision bearing is designed to accommodate significant axial loads in one direction simultaneously with radial loads, thanks to its defined 40° contact angle. Manufactured to a P6 (ABEC-3) tolerance class, it ensures high running accuracy and reliability. Its robust construction and optimized internal geometry make it an ideal choice for applications demanding high rigidity and stable operation at elevated speeds.
7218 BECBM Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| BE | Increased internal clearance and optimized internal design for higher speeds. |
| C | Designates a 40° contact angle, providing high axial load capacity. |
| BM | Indicates the bearing is lubricated with a high-performance grease suitable for the specified temperature range. |
7218 BECBM Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single row design with a steep 40° contact angle provides excellent resistance to axial loads in one direction and radial loads, making it suitable for combined load conditions. The optimized shoulder diameters on both rings ensure secure seating and enhanced support.
- High-Speed Performance: The brass cage (Cage material: Brass) ensures dimensional stability and low friction at high rotational speeds, contributing to a limiting speed of 6,300 rpm.
- Precision and Longevity: Manufactured from chrome steel for both rings and balls, and built to P6 tolerance, this bearing offers high dimensional accuracy, reduced vibration, and extended service life in demanding environments.
- Ready-to-Use Lubrication: The bearing comes pre-lubricated, ensuring immediate operational readiness and protection during the initial run-in period within its operating temperature range of -30°C to 110°C.
7218 BECBM Bearing Typical Application Areas
This angular contact ball bearing is ideally suited for high-performance machinery, including:
- Machine Tool Spindles
- High-Speed Pumps and Compressors
- Precision Gearboxes
- Agricultural and Construction Machinery
- Material Handling Systems
