Product Overview: The 7209 Angular Contact Ball Bearing
The 7209 bearing is a high-precision, single-row angular contact ball bearing, a vital component in our 7200 Series. Engineered with dimensions of 45x85x19mm, this bearing is specifically designed to handle combined (axial and radial) loads simultaneously. Its internal geometry features raceways in the inner and outer rings that are displaced relative to each other in the direction of the bearing axis. This design makes the 7209 ideal for applications requiring high rotational accuracy, speed, and rigidity, particularly where there is a significant axial load in one direction.
As a key part of our Angular Contact Ball Bearings range, the 7209 is manufactured from high-quality bearing steel to ensure durability and a long service life. These bearings are commonly mounted in pairs (e.g., back-to-back, face-to-face, or in tandem) to accommodate axial loads in both directions and provide a highly rigid bearing system.
Key Features of the 7209 Bearing
- Combined Load Support: Excellently accommodates both radial loads and high axial loads in a single direction.
- High-Speed Capability: The design is optimized for high-speed operation with minimal friction and heat generation.
- High Rigidity: Provides a high degree of stiffness, making it suitable for precision applications like machine tool spindles.
- Single-Row Design: Features a single row of balls with a specific contact angle for optimal load distribution.
- Precision Manufacturing: Produced to tight tolerances to ensure high running accuracy and consistent performance.
- Durable Construction: Made from premium-grade, through-hardened bearing steel for superior wear resistance and longevity.
