7218 BECBY Bearing Product Overview & Core Advantages
The 7218 BECBY is a single row angular contact ball bearing engineered for high-precision applications requiring superior performance under combined loads. Its defining feature is the 40° contact angle, which provides exceptional capacity for handling substantial axial loads in one direction, in addition to radial loads. Manufactured to P6 (ABEC-3) tolerance class, it ensures high running accuracy and reliability. The open design, combined with a robust brass cage, makes it an ideal choice for high-speed operation and demanding industrial environments.
7218 BECBY Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7218 | Standard bearing series designation indicating a 90mm bore, 160mm OD, and 30mm width. |
| BE | Designates a 40° contact angle and optimized internal geometry for high axial load capacity. |
| CB | Indicates a brass cage, providing strength, durability, and excellent performance at high speeds. |
| Y | Specifies that the bearing is pre-lubricated with a specific high-performance grease. |
7218 BECBY Bearing Structural Features & Performance Benefits
- Optimized Internal Geometry: The 40° contact angle and precisely calculated shoulder diameters (Inner ring large-side: 117.1 mm) are engineered to support high one-direction axial loads and radial loads simultaneously.
- High-Speed Capability: The combination of the brass cage and open design contributes to a high limiting speed of 5,000 rpm, reducing centrifugal forces and maintaining stability.
- Precision and Rigidity: Manufactured to P6 tolerance with strict dimensional control (bore tolerance: -0.015mm to 0), this bearing ensures precise shaft positioning and contributes to overall system high rigidity.
- Ready-to-Install: The bearing comes pre-lubricated, simplifying installation and providing immediate protection upon startup.
7218 BECBY Bearing Typical Application Areas
This angular contact ball bearing is ideally suited for machinery requiring high precision and speed. Key applications include:
- Machine Tool Spindles
- High-Speed Pumps and Compressors
- Precision Gearboxes
- Agricultural Machinery
- Material Handling Equipment
