Deep Groove Ball Bearings SKF 627 -2Z/C3

The SKF 627 -2Z/C3 deep groove ball bearing features compact dimensions of 7x22x7 mm, sheet metal shields on both sides and an increased C3 clearance for radial load capacity.

This single-row deep groove ball bearing 627 -2Z/C3 from SKF is designed primarily to accommodate radial loads as well as low axial forces in both directions. Manufactured from through-hardened 100Cr6 rolling bearing steel, this design features a sheet steel cage that precisely guides the rolling elements. With dimensions of a 7 mm bore, 22 mm outer diameter and 7 mm width, this rolling bearing is suitable for space-critical designs in precision engineering and general drive technology.

What is the 627-2Z/C3 deep groove ball bearing suitable for in industrial applications?

This deep-groove ball bearing is designed for compact bearing arrangements subject to predominantly radial loads and higher speeds. The cover plates on both sides protect the interior of the bearing from the ingress of coarse dirt particles, whilst the lubricant remains within the bearing chamber. As this is a non-contact gap seal, no additional friction is generated. The specified temperature range extends from –20 to +120 degrees Celsius.

What are the distinctive features of the version with C3 radial clearance and 2Z cover rings?

The suffix C3 indicates a slightly increased radial bearing clearance compared with the standard version. This additional radial clearance compensates for thermal expansion at operating temperatures and helps to prevent seizing if the inner and outer rings are fitted with tight fits. The designation 2Z stands for cover plates made of sheet steel, pressed in on both sides. The bearings are manufactured to tolerance class P0/PN or ABEC 1, with a cylindrical outer ring without a ring groove or flange.
