7218 BEP Bearing Product Overview & Core Advantages
The 7218 B angular contact ball bearing is a precision single-row bearing engineered for high-performance applications. Designed to accommodate combined loads—simultaneously handling significant radial and axial loads—this bearing features a 40° contact angle for optimal thrust capacity. Its P6 (ABEC-3) tolerance class ensures exceptional running accuracy, making it ideal for demanding, high-speed machinery requiring superior rotational precision and high rigidity.
7218 BEP Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7218 | Standard bore diameter (90 mm), outside diameter (160 mm), and width (30 mm) dimensions. |
| B | Denotes a 40° contact angle, providing higher axial load capacity compared to standard angular contact bearings. |
| Open | No seals or shields, allowing for higher speed operation and enabling custom lubrication regimes. |
| Nylon Cage | Lightweight polymer cage contributes to high-speed performance, reduced friction, and smooth operation. |
7218 BEP Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single-row design with a steep 40° contact angle provides excellent resistance to combined radial and axial loads, ensuring stable operation under demanding conditions.
- Optimized for High Speeds: The lightweight nylon cage minimizes centrifugal forces, enabling a high limiting speed of 4,500 rpm. The open design facilitates efficient lubrication and heat dissipation.
- Precision Engineering: Manufactured to P6 (ABEC-3) tolerance standards, this bearing guarantees precise shaft positioning and low vibration, which is critical for high-precision machinery.
- Robust Material Construction: Made from chrome steel for both rings and balls, the bearing offers high durability, wear resistance, and a long operational lifespan.
7218 BEP Bearing Typical Application Areas
The 7218 B is ideally suited for applications requiring high speed, precision, and reliable performance under combined loads. Common uses include:
- Machine Tool Spindles
- High-Speed Pumps and Compressors
- Precision Gearboxes
- Industrial Robotics and Automation Equipment
- Agricultural and Construction Machinery
