Overview
The SKF 6320 C3S1 is a precision deep groove radial ball bearing engineered for high-speed applications requiring low friction, minimal noise, and consistent performance. With an inner diameter of 100 mm, outer diameter of 215 mm and thickness of 47 mm, this bearing accommodates both radial and axial loads in dual directions, making it versatile for demanding industrial environments.
Key Features
- Deep groove ball bearings are widely used, featuring low friction and optimization for low noise and low vibration enabling high rotational speeds
- Accommodate radial and axial loads in both directions, are easy to mount and require less maintenance than other bearing types
- C3 suffix indicates increased internal clearance, often referred to as high-speed, meaning the bearing is designed for high rotational speeds and moderately high temperatures
- Open design provides maximum cooling and is suitable for clean, controlled environments
- Chrome steel construction ensures durability and corrosion resistance

Typical Applications
In industrial settings, the 6320 C3S1 bearing is widely used in heavy machinery like pumps and compressors, thanks to its robust radial load capacity. In automotive applications, such as wheel hubs and transmissions, the C3 clearance accommodates thermal expansion. The bearing excels in conveyor systems and agricultural equipment, handling high radial loads with ease. Additional uses include electric motors, gearboxes, and industrial automation equipment where high-speed operation and reliable radial load support are critical.
