Deep Groove Ball Bearings SKF 61807

The SKF 61807 deep groove ball bearing, with its compact dimensions of 35 × 47 × 7 mm, offers a space-saving solution for light-duty and precision bearing applications.

The 61807 deep groove ball bearing is a single-row rolling bearing in an exceptionally narrow design, with a bore diameter of 35 mm, an outer diameter of 47 mm and a width of just 7 mm. Thanks to this extremely small cross-section, this bearing – made from standard rolling bearing steel (100Cr6) – is particularly suitable for designs where radial installation space is limited. Manufactured by SKF to tolerance class P0/PN (ABEC 1), this open bearing primarily withstands radial loads as well as moderate axial forces.

What are the industrial applications of the 61807 deep groove ball bearing?

Design engineers use the 61807 deep groove ball bearing wherever a large shaft diameter needs to be combined with a small outer diameter and low weight. Typical applications include compact assemblies in mechanical engineering where small cross-sections are required. Thanks to its dimensionally stable sheet steel cage, the bearing guides the rolling elements precisely at constant speeds. As it is an open bearing, it can be flexibly integrated into the overall system using external lubricants.

What are the key considerations regarding the open design and standard bearing clearance?

As the 61807 model is designed without integrated sealing washers, you must ensure the supply of lubricant and protection against dirt via the surrounding housing. The bearing has standard radial clearance, which is designed for typical installation conditions with small temperature differences between the shaft and the housing. The permissible temperature range is from –20 to +120 degrees Celsius. Before assembly, check the cylindrical bearing seats to prevent deformation of the thin-walled outer ring.
