Product Overview: The 7204 Angular Contact Ball Bearing
The 7204 bearing is a single-row angular contact ball bearing designed for high-precision and high-speed applications. With key dimensions of 20mm bore diameter, 47mm outer diameter, and 14mm thickness, this component is part of our 7200 Series of Angular Contact Ball Bearings. These bearings are engineered with raceways in the inner and outer rings that are displaced relative to each other in the direction of the bearing axis. This design allows them to accommodate combined loads—simultaneously supporting both radial and axial loads. The axial load carrying capacity increases as the contact angle increases, making the 7204 an excellent choice for applications requiring rigidity and high load support in a single direction.
Key Features of the 7204 Bearing
- High Axial Load Capacity: Specifically designed to handle significant axial loads in one direction, in addition to radial loads.
- High-Speed Performance: The internal geometry is optimized for high rotational speeds, minimizing friction and heat generation.
- Single-Direction Thrust: Effectively manages thrust loads in one direction, making it ideal for specific machinery requirements.
- Versatile Mounting Options: Can be mounted in pairs (back-to-back, face-to-face, or tandem arrangements) to handle combined loads and provide system rigidity.
- Precision Engineering: Manufactured to tight tolerances to ensure high running accuracy and reliable performance.
- Durable Construction: Made from high-purity, hardened bearing steel for exceptional durability and a long operational lifespan.
