Deep Groove Ball Bearings SKF 61820

The SKF 61820 deep-groove ball bearing is an open, thin-section bearing measuring 100 × 125 × 13 mm, designed for industrial applications where space is at a premium.

The 61820 deep groove ball bearing is a single-row rolling bearing from SKF, specifically designed for applications with limited radial installation space. With an inside diameter of 100 mm, an outside diameter of 125 mm and a narrow width of 13 mm, this design offers a very slim profile. The open bearing is made from standard roller bearing steel (100Cr6) and is suitable for withstanding predominantly radial loads as well as light axial loads in both directions.

What is the 61820 deep groove ball bearing suitable for?

The deep groove ball bearing 61820 is primarily used where there is limited radial installation space available for large shaft diameters. Typical applications can be found in general mechanical engineering in bearing arrangements with a low cross-sectional height. Thanks to the integrated sheet steel cage and the defined temperature range of -20 to +120 degrees, the design is suitable for constant speeds in protected installation environments with external housing seals or a central lubrication supply.

What are the characteristics of the open design with standard clearance?

As an open bearing, this design has no integrated sealing washers, which means that lubricants such as oil or grease can reach the rolling elements unhindered. Designers should therefore ensure that the bearing housing is externally sealed to prevent the ingress of contaminants. The bearings are manufactured to tolerance class P0/PN (ABEC 1) with standard radial clearance. At typical operating temperatures and with standard fits, this combination provides a balanced clearance between the rolling elements and raceways, ensuring smooth running.
