Deep Groove Ball Bearings FAG 623 -2Z

The FAG 623-2Z deep-groove ball bearing, with its compact dimensions of 3 × 10 × 4 mm and end shields on both sides, is suitable for a wide range of applications in small drives.

This single-row 623-2Z deep-groove ball bearing from FAG accommodates radial forces as well as light axial loads in both directions. Manufactured from standard 100Cr6 rolling-bearing steel, this miniature bearing is characterised by dimensional stability and smooth concentricity. A sheet steel cage guides the rolling elements evenly along the raceway. Thanks to its standard radial clearance, the bearing is suitable for designs with standard fits and operating temperatures ranging from -30 to +120 degrees Celsius.

For which applications is the 623-2Z deep-groove ball bearing designed?

Design engineers and maintenance technicians use this miniature design primarily in compact devices, small electric motors and precision instruments. The rolling bearing, which has no flange or groove on the outer ring, can be fitted flush into cylindrical housing bores. This design proves its worth wherever limited installation space meets shafts with a 3 mm diameter. It serves as a bearing component for smooth rotational movements in precision engineering and drive technology.

What features do the cover plates of the -2Z variant offer?

The suffix -2Z indicates that both sides are covered by non-contact gap seals made of sheet metal. These cover plates protect the interior of the bearing from the ingress of dust and dirt particles and help to retain the lubricant within the bearing. As there is no frictional contact with the inner ring, no additional friction losses occur compared with sliding seals. The tolerance class P0/PN or ABEC 1 meets standard requirements in mechanical engineering.
