Deep Groove Ball Bearings FAG 16018 -C3

The FAG single-row deep groove ball bearing 16018 -C3, with a 90 mm bore and increased bearing clearance, offers defined running characteristics at elevated operating temperatures.

The 16018 -C3 deep groove ball bearing is a single-row radial ball bearing in a standard design without integrated sealing washers. Manufactured from standard roller bearing steel (100Cr6), this component primarily accommodates radial loads as well as moderate axial forces in both directions. The open design allows for the direct supply of grease or lubricating oil from the surrounding housing. The manufacturer, FAG Rolling Bearings, produces the component to the universal standard tolerance P0/PN (corresponding to ABEC 1) and without a flange or groove on the outer ring.

In which applications is the 16018-C3 deep groove ball bearing used?

This rolling bearing is particularly suitable for mounting positions with a 90 mm shaft diameter where the installation space is limited in the axial direction. Thanks to its narrow design, with a width of 16 mm and an outer diameter of 140 mm, this version allows for compact housing designs. The bearing is suitable for mechanical assemblies in which external seals protect against contamination and lubrication is supplied from the outside.

What does the C3 clearance rating mean for this open bearing?

The suffix C3 indicates a slightly increased radial clearance compared with the standard version. This increased distance between the rolling elements and raceways compensates for thermal expansion that occurs due to temperature differences between the shaft and the housing. Tight fits also reduce the operating clearance after installation. With a permissible temperature range of -20 to +150 degrees and a sheet steel cage, smooth running is maintained even at higher operating temperatures.
