Deep Groove Ball Bearings FAG 6407 -C3

The FAG 6407-C3 deep-groove ball bearing, with a 35 mm bore, 100 mm outer diameter and increased bearing clearance, offers a high load-carrying capacity under thermal stress.

The FAG 6407-C3 single-row deep groove ball bearing is an open rolling bearing for industrial applications involving predominantly radial loads. Manufactured from standard roller bearing steel 100Cr6, this component withstands demanding operating conditions within a temperature range of -30 to +150 degrees. The robust sheet steel cage guides the rolling elements precisely, whilst manufacture to tolerance class P0 (ABEC 1) ensures a precise fit in the housing and on the shaft.

What is the 6407 -C3 deep groove ball bearing suitable for in industrial applications?

Design engineers primarily use the 6407 -C3 deep groove ball bearing in drives, gearboxes and machinery where radial forces are present and moderate axial forces in both directions need to be supported. The solid design, with an outer diameter of 100 mm and a width of 25 mm, is suitable for drive shafts subject to high loads. As an open design without a flange or groove, the bearing can be integrated directly into enclosed housings, where an existing lubrication circuit provides cooling and lubrication.

Why is the increased bearing clearance (C3) relevant for this design?

The designation C3 indicates a slightly increased radial bearing clearance compared with the standard version. This additional clearance between the inner ring, outer ring and rolling elements compensates for fit allowances during press-fitting as well as thermal linear expansion during operation. If heat builds up on the shaft during operation, the increased radial clearance counteracts any stress on the bearing. When using this open bearing, always ensure the housing is fitted with an external seal to prevent lubricant loss and the ingress of contaminants.
