Product Overview: The 5218 Double-Row Angular Contact Ball Bearing
The 5218 bearing is a high-capacity component from our 5200 Series of Angular Contact Ball Bearings. With dimensions of 90x160x52.4mm, this bearing features a double-row design, which is dimensionally similar to two single-row angular contact ball bearings arranged back-to-back but with a narrower width. This configuration allows it to accommodate high radial loads and axial loads in both directions, making it an excellent choice for applications requiring high rigidity and the ability to handle combined loads effectively.
As a trusted supplier of industrial and mechanical parts, we ensure our 5218 bearings are manufactured to precise industry standards. Their robust construction and ability to manage complex load scenarios make them indispensable in many demanding industrial environments. The design provides a stiff bearing arrangement, suitable for applications where moment loads are present.
Features of the 5218 Bearing
- Double-Row Design: Offers the capacity of two single-row bearings in a more compact, space-saving unit.
- Combined Load Capability: Engineered to support high radial loads and axial loads acting in both directions simultaneously.
- High Rigidity: Provides a stiff and stable bearing arrangement, ideal for applications that require minimal shaft displacement.
- Bi-Directional Axial Support: Capable of locating the shaft axially in both directions with a specific axial clearance or preload.
- Durable Construction: Manufactured from high-quality, high-purity bearing steel for enhanced durability and extended service life.
- Precision Engineering: Produced to strict tolerances to ensure consistent and reliable performance under heavy loads.
Applications of 5218 Bearings
- Industrial Gearboxes: Provides rigid support for gear shafts, ensuring proper mesh and power transmission.
- Pumps and Compressors: Used to support rotating shafts, handling the combined loads typical in fluid machinery.
- Machine Tool Spindles: Offers the high rigidity required for precision cutting and milling operations.
- Hoisting Equipment and Cranes: Suitable for sheaves and transmission systems where heavy radial and axial forces are present.
- Electric Motors and Generators: Supports motor shafts, providing stable rotation under various load conditions.
- Material Handling Systems: Utilized in conveyor pulleys, lifts, and other equipment requiring robust support.
- Agricultural Machinery: Applied in gear drives and power transmission units of tractors and other farm equipment.
Benefits of Using the 5218 Bearing
- Enhanced Load Capacity: The double-row configuration significantly increases the load-carrying capability compared to a single-row bearing of similar size.
- Space Efficiency: Achieves the performance of a paired bearing set in a narrower profile, saving axial space in machine designs.
- Increased Operational Stability: High rigidity minimizes deflection and vibration, leading to smoother and more precise machinery operation.
- Simplified Assembly: As a single unit, it is easier to handle and mount than two separate single-row bearings.
- Extended Service Life: Robust design and high-quality materials reduce wear and extend the operational life, even in demanding applications.
- Cost-Effective Solution: Provides a high-performance, rigid bearing arrangement without the complexity and cost of pairing two separate bearings.
