Deep Groove Ball Bearings FAG 16038 -C3

The FAG 16038 -C3 deep-groove ball bearing is an open rolling bearing with a 190 mm bore, designed for radial loads and industrial applications subject to thermal stress.

The 16038 -C3 deep groove ball bearing is a single-row roller bearing from FAG, designed for industrial applications involving high radial loads. With dimensions of 190 mm inner diameter, 290 mm outer diameter and a width of 31 mm, this component is suitable for large-scale shaft mountings. Manufactured from standard 100Cr6 rolling bearing steel, the component primarily absorbs radial forces as well as moderate axial forces in both directions. The design without an integrated seal allows for straightforward lubrication directly via the housing system.

What is the 16038-C3 deep groove ball bearing suitable for in industrial plant?

This rolling bearing is primarily used on mounted shafts with a diameter of 190 mm that are operated under continuous load. Thanks to the integrated sheet steel cage and the wide temperature range of -20 to +150 degrees, the bearing is designed for environments where heat is generated during operation. As it is an open bearing without a flange or groove on the outer ring, it can be flexibly fitted into cylindrical housing bores and lubricated externally with oil or grease.

What does the C3 clearance rating mean for the 16038-C3 deep groove ball bearing?

The suffix C3 indicates a slightly increased radial clearance compared with the standard version. This increased clearance between the inner ring, outer ring and the rolling elements helps to prevent seizing if the shaft or bearing rings heat up and expand during operation. The C3 version is specifically recommended for tight fits on the shaft or where there are temperature differences between the inner and outer rings. For standard applications without thermal expansion, the standard tolerance is usually sufficient, whilst C3 offers additional operational reliability under thermal stress.
