Deep Groove Ball Bearings SKF 16021

The SKF 16021 deep groove ball bearing, with a bore of 105 mm and a width of 18 mm, offers compact dimensions for radial guidance in mechanical engineering.

The 16021 deep groove ball bearing is designed as a single-row rolling bearing in the narrow 160 series. Thanks to its narrow cross-sectional width, this design is suitable for applications with limited radial and axial installation space. The bearing is made from standard rolling-element bearing steel (100Cr6) and primarily accommodates radial loads as well as low axial forces in both directions. As it is an open bearing without integrated seals, it can be lubricated directly with oil or grease via the machine’s lubrication system.

What are the practical applications of the 16021 deep groove ball bearing?

Typical applications are found in general mechanical engineering and in gearbox designs where a compact bearing arrangement is required. The open bearing design allows for use in enclosed housings containing a lubricant bath. Thanks to its SKF Explorer quality construction and sheet steel cage, the 16021 deep groove ball bearing supports shafts at speeds typical for single-row radial ball bearings. The permissible temperature range is from –20 to +120 degrees Celsius.

What significance do tolerance class P6 and the open design have for installation?

This rolling bearing features enhanced dimensional accuracy in accordance with tolerance class P6, whilst its running accuracy corresponds to class PN. The tighter dimensional tolerance facilitates fits on both the shaft and housing and promotes uniform concentricity within the system. As no sealing washers are fitted, protection against dirt particles is provided by the surrounding housing. The standard radial bearing clearance is designed to ensure that the bearing runs with the correct operating clearance under standard mounting fits and at normal operating temperatures.
