Deep Groove Ball Bearings SKF 619/7

The SKF 619/7 deep groove ball bearing is a compact, open rolling bearing measuring 7x17x5 mm, designed for space-saving shaft mountings.

The SKF 619/7 deep groove ball bearing is a single-row rolling bearing belonging to the thin-section bearing series and is designed to withstand radial and moderate axial loads. Thanks to its slim dimensions – with a 7 mm bore, 17 mm outer diameter and 5 mm width – the component is primarily used in precision mechanical designs and compact shaft guides. Manufactured from standard rolling-element bearing steel (100Cr6), the ball bearing offers a tried-and-tested material basis for industrial applications.

In which installation situations is the deep-groove ball bearing 619/7 used?

This bearing is particularly suitable for installation locations with very limited space, where low rotating masses and smooth running are required. Designs with small radial cross-sections benefit from the slim design. As the rolling elements are guided by a sheet steel cage, friction during operation remains low. Designers specifically use this design to reduce weight and minimise the required installation space in rotating systems.

When is the open design of the 619/7 deep groove ball bearing advantageous?

The open design without integrated sealing washers offers the lowest rotational resistance, as no sliding seal presses against the inner ring. This enables high speeds and low-friction operation within a temperature range of -20 to +120 degrees Celsius. However, the bearing location requires a clean installation environment or a housing-side seal to protect against dirt and moisture. Lubrication with oil or grease is applied from the outside and can be flexibly adapted to your operating conditions.
