Deep Groove Ball Bearings SKF 6018

The SKF 6018 deep groove ball bearing, measuring 90x140x24 mm, features an open design for radial load transmission in mechanical engineering.

The 6018 deep groove ball bearing is a single-row radial ball bearing in an open design, made from 100Cr6 rolling bearing steel. As a bearing in the SKF Explorer performance class, it combines a standard radial bearing clearance with increased dimensional accuracy to tolerance class P6 and running accuracy to PN. Due to its open design, this rolling bearing is particularly suitable for applications where the lubricant can circulate freely or where a surrounding housing provides the external seal.

What is the 6018 deep groove ball bearing suitable for in industrial applications?

The design is primarily intended to accommodate high radial loads during operation. The deep raceways in the inner and outer rings also accommodate moderate axial forces in both directions. Typical areas of application include industrial applications with a rotating shaft and external housing sealing. A sheet steel cage guides the rolling elements evenly at constant speeds. The rolling bearing is thermally rated for operating environments ranging from –20 to +120 degrees.

What features do tolerance class P6 and the open design offer?

In this design, tolerance class P6 implies tighter dimensional accuracy for the bore and outer diameter compared to the basic standard. This ensures a precise bearing fit on the 90 mm shaft and within the housing. As the bearing is supplied by the manufacturer without seals, the lubricant can be freely selected to suit the operating conditions. During assembly, care must be taken to ensure that no foreign particles enter the interior and that external seals protect the bearing environment.
