Open Deep Groove Ball Bearings: One of the most commonly used bearings, the open types are manufactured without seals to allow for the free circulation of either oil or grease, used in gearboxes and other environments where no foreign matter would be present and a lubricant supply is available.
Benefits: Used widely in transmissions etc, can be used in oil or greased, cost effective solution
Features of bearing 6811
- Deep-groove geometry for high speeds and supporting both radial and axial loads
- Single-row bearing for supporting radial loads
- Normal radial internal clearance for applications that do not involve thermal expansion or atypical precision
- Pressed steel cage evenly spaces the balls for even load distribution and prevents contact to reduce friction, vibrations, and noise
- Open bearing for lubrication in place and for use in applications with little exposure to dirt, grime, debris, and other contaminants
