Deep Groove Ball Bearings FAG 623

The FAG 623 deep-groove ball bearing accommodates both radial and axial loads whilst maintaining compact dimensions of 3 × 10 × 4 mm.

This single-row FAG 623 deep-groove ball bearing is characterised by its compact design and is manufactured from standard rolling-bearing steel (100Cr6). This miniature bearing is used wherever rotational movements with low frictional resistance need to be guided within very confined spaces. Thanks to its flangeless, grooveless cylindrical outer ring, the bearing can be fitted precisely into corresponding cylindrical housing bores.

What is the FAG 623 deep groove ball bearing suitable for?

This miniature bearing is suitable for designs with limited installation space, where small shaft diameters and moderate loads are present. The deep groove geometry of the raceways primarily absorbs radial forces, but, due to its design, also supports axial forces in both directions. Thanks to the integrated sheet steel cage, the rolling elements remain at a uniform distance apart even during dynamic rotational movements. The material design allows for an operating temperature range of -30 to +120 degrees Celsius in the intended assemblies.

What are the characteristics of the open design with standard bearing clearance?

As an open rolling bearing, this variant is supplied ex-works without either cover plates or sealing plates. The absence of abrasive sealing lips keeps rotational resistance to a minimum, which promotes smooth running and low torques. The lubricant can reach the raceways directly, but protective measures against ingress of dirt are required in the surrounding environment. The manufactured tolerance class P0/PN (corresponding to ABEC 1) and the standard radial clearance are tailored to common installation conditions for standard shaft and housing fits.
