Deep Groove Ball Bearings SKF 627 -2Z

SKF 627-2Z deep groove ball bearing (7x22x7 mm): A single-row rolling bearing with cover plates on both sides to protect against dirt particles, designed for compact installation spaces.

The SKF 627 -2Z deep groove ball bearing is a compact, single-row radial ball bearing for shafts with a 7 mm diameter. Manufactured from 100Cr6 bearing steel, this bearing primarily accommodates radial forces as well as moderate axial loads in both directions. A sheet steel cage guides the rolling elements evenly in the deep raceways. As part of the SKF Explorer range, the design is characterised by smooth running and low friction.

In which applications is the 627-2Z deep-groove ball bearing used?

This miniature deep-groove ball bearing is typically used in smaller rotating assemblies with limited installation space. Typical applications include compact shaft mountings, precision mechanical designs and rotating components with limited radial installation space. Design engineers and maintenance technicians utilise the dimensions of 22 mm outer diameter and 7 mm width to create space-saving designs that operate at temperatures between –20 and +120 degrees.

What features do the double-sided 2Z cover plates offer?

The suffix ‘-2Z’ denotes non-contacting cover plates made from pressed sheet steel on both sides of the bearing. These gap seals shield the interior against the ingress of larger dirt particles and dust without generating additional frictional torque. This makes the bearing suitable for higher speeds with minimal heat build-up. The standard radial bearing clearance, in combination with tolerance class P0 (ABEC 1), provides a balanced operating clearance for common fit conditions on shafts and housings.
