Deep Groove Ball Bearings SKF 627

The SKF 627 deep groove ball bearing is an open rolling bearing measuring 7x22x7 mm, designed to accommodate radial and axial loads in confined spaces.

This single-row deep-groove ball bearing 627 belongs to the miniature bearing series and is manufactured by SKF in the Explorer version. The component supports rotating shafts and primarily accommodates radial forces as well as moderate axial forces in both directions. Manufactured from through-hardened standard roller bearing steel (100Cr6), the bearing complies with tolerance class P0/PN or ABEC 1. It is designed for compact shaft mountings that require low-friction operation and defined running characteristics.

What is the 627 deep groove ball bearing suitable for?

This deep-groove ball bearing is primarily used in compact designs with limited radial and axial installation space. Thanks to the deep raceway geometry, the design accommodates not only the main radial load but also axial guiding forces in both directions. Typical applications include compact assemblies and precision mechanical axes where small dimensions – with an outer diameter of 22 mm and a 7 mm bore – are required.

What distinguishes the 627 deep-groove ball bearing as an open bearing?

As an open bearing, this variant does not feature integrated cover plates or sealing discs, which means no additional sealing friction is generated during operation. This enables smooth start-up and makes it suitable for assemblies with an external lubricant supply. The following applies during operation: the bearing location must be protected against the ingress of dirt and moisture by the customer. The built-in sheet steel cage guides the rolling elements within the permissible temperature range of –20 to +120 degrees Celsius.
