Deep Groove Ball Bearings FAG 6018 -C3

The FAG 6018-C3 deep-groove ball bearing, with a 90 mm bore and increased C3 clearance, offers reliable operation at higher operating temperatures.

The FAG 6018-C3 single-row deep groove ball bearing accommodates radial loads as well as moderate axial forces in both directions. Manufactured from standard rolling-element bearing steel 100Cr6, this version has the main dimensions 90 x 140 x 24 mm. The open design, without integrated sealing washers, allows for direct lubricant supply via the surrounding housing. Thanks to the robust sheet steel cage, the bearing guides the rolling elements smoothly at temperatures ranging from –20 to +150 degrees Celsius.

What is the 6018-C3 deep groove ball bearing suitable for?

Applications in general mechanical engineering frequently use this design on shafts with a diameter of 90 mm. Owing to its open design, the bearing is particularly suitable for oil- or grease-lubricated installations where external seals prevent the ingress of dirt particles. The version with standard tolerance P0/PN or ABEC 1 meets the classic requirements of drive technology and maintenance.

What does the C3 bearing clearance mean for this version?

The designation C3 indicates an increased radial bearing clearance compared with the standard version. If the shaft and bearing rings expand due to temperature differences during operation, this additional clearance counteracts any stress on the rolling elements. Tight fits on the shaft also reduce the bearing clearance after press-fitting. Before installation, check whether the operating temperatures and fit conditions require the increased operating clearance.
