Deep Groove Ball Bearings FAG 6018 -M-C3

The FAG 6018 -M-C3 deep groove ball bearing, with a 90 mm bore and a brass cage, can accommodate combined loads at elevated operating temperatures.

The 6018 -M-C3 deep groove ball bearing is a single-row rolling bearing made from case-hardened standard bearing steel (100Cr6) for demanding industrial applications. The open design, without abiding washers, allows for targeted lubrication with grease or oil via the surrounding housing system. FAG manufactures this version with a guided brass cage and a slightly increased radial clearance. This ensures that the bearing assembly remains functional even in the event of operational heating and expansion of the shaft.

What is the 6018 -M-C3 deep groove ball bearing suitable for in industrial applications?

This design is primarily suitable for stationary machine mountings and rotating shaft systems subject to combined loads. The single-row deep-groove ball bearing transmits high radial forces and, via its deep raceways, absorbs axial forces on both sides. Thanks to its solid brass cage, the rolling bearing is suitable for operating conditions involving mechanical vibrations or sudden accelerations. Within the specified temperature range of –30 to +150 degrees Celsius, the unit ensures smooth running characteristics in heat-stressed environments.

What role do the brass cage and C3 bearing clearance play in bearing design?

The suffix C3 denotes an increased radial bearing clearance compared to the standard tolerance. This additional operating clearance compensates for fit oversizes following press-fitting onto the shaft, as well as temperature differences between the inner and outer rings during operation. This design reduces the risk of the rolling elements becoming unacceptably jammed. Compared with simple standard cages, the brass cage is characterised by high resistance to shock loads and critical lubrication conditions.
