Deep Groove Ball Bearings SKF 6311

The SKF 6311 deep groove ball bearing, with dimensions of 55x120x29 mm, is primarily designed to accommodate radial loads in industrial bearing arrangements.

The SKF 6311 deep groove ball bearing is a single-row rolling bearing designed for industrial applications that accommodate radial forces as well as moderate axial forces. The open bearing is made from standard rolling-element bearing steel (100Cr6) and is manufactured in the SKF Explorer design. With a bore of 55 mm, an outside diameter of 120 mm and a width of 29 mm, the ball bearing fits into corresponding shaft designs in mechanical engineering.

What loads can the 6311 deep-groove ball bearing withstand?

The 6311 deep groove ball bearing is primarily used on rotating shafts subject to radial forces where low friction losses are required. Thanks to its open design, the component can be fitted directly into lubricated machine housings where a circulating lubricant system is in place.

The sheet steel cage guides the rolling elements evenly into the deep raceways of both rings. This makes this single-row radial ball bearing suitable for medium to high speeds whilst ensuring smooth running.

What are the practical advantages of the open design of the 6311 bearing?

As an open component without integrated sealing washers, the bearing housing requires external sealing against particles and moisture. The open design allows for the free choice of lubricant and facilitates the supply of grease or lubricating oil during operation.

During assembly, the standard radial bearing clearance and the standard tolerance class (P0/PN or ABEC 1) must be taken into account. With a thermal operating range of –20 to +120 degrees, the component covers the typical temperature ranges found in industrial environments.
