Deep Groove Ball Bearings SKF 626 -Z

The SKF 626-Z deep-groove ball bearing, with dimensions of 6x19x6 mm and a single-sided cover, offers protection against dirt whilst maintaining low rotational resistance.

The 626-Z deep groove ball bearing is a compact, single-row miniature roller bearing for shafts with a diameter of 6 mm. The design primarily accommodates radial loads and guides the shaft precisely within the housing. Thanks to its manufacture from standard roller bearing steel (100Cr6), this bearing is well-suited to equipment with limited installation space. It combines a compact design with smooth guidance of the rolling elements within the sheet steel cage.

What is the 626-Z deep groove ball bearing suitable for?

This miniature bearing is primarily used in compact shaft mountings where radial installation space is limited. With an outer diameter of 19 mm and a width of 6 mm, the bearing fits into narrow bearing seats. The component is suitable for designs where normal radial loads occur at medium to high speeds and where frictional resistance must remain low.

When is the single-sided Z cover plate recommended?

The version with the suffix ‘Z’ features a non-contacting sheet metal cover on one side of the bearing. This cover shields the interior from coarse dirt particles without causing friction losses. The open opposite side allows lubricant to be applied directly where required. This variant is primarily intended for installation scenarios where one side of the bearing needs to remain open towards the interior of the housing, whilst the outer side is protected against the ingress of dirt.
