Deep Groove Ball Bearings SKF 625 -2Z

The SKF 625-2Z deep groove ball bearing has compact dimensions of 5 × 16 × 5 mm and is protected against coarse particles by sheet metal covers on both sides.

The SKF 625-2Z deep groove ball bearing is a compact, single-row miniature roller bearing designed for precision mechanical applications. The bearing has a bore of 5 mm, an outside diameter of 16 mm and a width of 5 mm. As part of the SKF Explorer performance class, this roller bearing combines a tailored internal geometry with roller bearing steel (100Cr6). The design primarily accommodates radial loads and supports shafts whilst requiring minimal installation space.

What is the 625-2Z miniature bearing suitable for?

This miniature deep-groove ball bearing is primarily used where installation space and mass are severely limited. Typical applications include compact precision mechanical assemblies and measuring devices. As the single-row bearing can accommodate not only radial forces but also moderate axial forces in both directions, it is suitable for use as a fixed or floating bearing on slender shafts. A cylindrical outer ring without a flange or groove facilitates direct press-fitting into smooth housing bores.

What advantage do the 2Z cover plates offer with this bearing?

The double-sided cover with non-contacting cover plates made of sheet steel (suffix -2Z) shields the interior of the bearing against the ingress of larger dirt particles and dust. At the same time, the discs retain the grease applied at the factory inside the bearing. As the gap seals do not come into contact with the inner ring, no additional friction is generated. This ensures smooth start-up behaviour and high speeds at operating temperatures between –20 and +120 degrees.
