Deep Groove Ball Bearings SKF 6211

The SKF 6211 deep groove ball bearing is an open, single-row radial ball bearing with main dimensions of 55x100x21 mm, designed for a wide range of industrial applications.

The SKF 6211 deep groove ball bearing is one of the tried-and-tested rolling bearings used in industrial engineering. The component is made from standard 100Cr6 rolling bearing steel and houses the rolling elements in a sturdy sheet steel cage. With an inner diameter of 55 mm, an outer diameter of 100 mm and a width of 21 mm, this Explorer version can withstand high radial and moderate axial loads. It thus provides a functional component for rotationally symmetrical shaft mountings.

For which loads is the 6211 deep groove ball bearing suitable?

This single-row bearing is suitable for rotating shafts subjected to predominantly radial and moderate axial loads. Thanks to its open design, lubricant can reach the rolling elements unhindered, which makes it ideal for use in oil- or grease-lubricated housings. SKF’s Explorer design is engineered for smooth running during continuous operation and ensures precise guidance at operating temperatures between –20 and +120 degrees.

When is the open design of the 6211 deep groove ball bearing appropriate?

The open design without integrated seals enables a low friction torque during operation. External housing seals take on the task of protecting the interior from contamination and lubricant loss. With standard radial bearing clearance and tolerance class P0/PN (ABEC 1), the component fits precisely into standard bearing seats. In closed oil circuits, the open design allows for the continuous circulation of the lubricant directly around the balls.
