Deep Groove Ball Bearings SKF 626

The SKF 626 deep groove ball bearing is a compact, open miniature bearing measuring 6x19x6 mm, designed for a wide range of industrial applications.

The SKF 626 deep groove ball bearing is a single-row rolling bearing designed for compact installations with demanding rotational requirements. With a bore of 6 mm, an outside diameter of 19 mm and a width of 6 mm, this miniature bearing primarily accommodates radial loads as well as moderate axial forces. Manufactured from standard roller bearing steel (100Cr6) in the Explorer design, the product combines optimised internal geometries with smooth running. When you purchase this roller bearing, you receive a precision-manufactured component for new designs or maintenance work.

In which applications does the 626 deep-groove ball bearing prove its worth?

Design engineers and maintenance technicians prefer to use the 626 deep-groove ball bearing in small electric motors, measuring instruments and precision mechanical drives. Thanks to its compact dimensions, this design is suitable for applications with limited installation space where precise shaft guidance is required. As the open design does not require any sealing lips that could cause friction, the bearing operates with low frictional resistance when the housing is suitably lubricated.

What are the distinctive features of the open design and tolerance class P0 in the 626?

This model has no integrated sealing washers. The open bearing therefore requires a clean environment and an external supply of lubricant within the housing, for example oil or grease. With the standard radial bearing clearance, the bearing is suitable for standard operating conditions within a temperature range of –20 to +120 °C. The P0 tolerance class (corresponding to ABEC 1), the cylindrical outer ring without a groove, and the dimensionally stable sheet steel cage ensure low-vibration operation and smooth guidance of the rolling elements.
