Product Overview: The 7208 Angular Contact Ball Bearing
The 7208 bearing is a high-precision component within our distinguished 7200 Series Angular Contact Ball Bearings. Engineered for applications that involve both radial and axial loads, this bearing excels particularly in scenarios where high speeds and precision are critical. Its design allows it to accommodate axial loads in one direction, while a single bearing can only take axial load in one direction. For axial loads in both directions, or for higher load capacity, a pair of 7208 bearings can be arranged in a duplex configuration (e.g., O-arrangement or X-arrangement).
With a bore diameter of 40mm, an outer diameter of 80mm, and a thickness of 18mm, the 7208 bearing provides robust performance. As a trusted supplier of industrial bearings and mechanical parts, we ensure our 7208 bearings meet stringent quality standards, providing reliable operation and extended service life in demanding industrial environments. These bearings are vital for maintaining optimal performance in a wide array of machinery.
Features of the 7208 Bearing
- High Speed Capability: Designed to operate efficiently at very high rotational speeds, making them suitable for fast-moving machinery.
- Combined Load Support: Capable of accommodating both significant radial and axial loads simultaneously, primarily in one direction.
- Precision Performance: Manufactured to close tolerances, ensuring high running accuracy and rigidity for precise applications.
- Optimal Ball and Raceway Contact: Features a contact angle that allows for the effective distribution of loads across the raceways.
- Durable Construction: Made from high-grade bearing steel to ensure excellent wear resistance and long-term reliability even under challenging conditions.
- Duplex Mounting Versatility: Can be mounted in pairs (back-to-back, face-to-face, or tandem) to handle axial loads in both directions or to increase rigidity and load capacity.
