Deep Groove Ball Bearings FAG 6056 -M-C3

The FAG 6056 -M-C3 deep-groove ball bearing, with dimensions of 280 × 420 × 65 mm, a brass cage and C3 clearance, provides a solid basis for large bearings subjected to thermal stress.

The 6056 -M-C3 deep groove ball bearing is a single-row radial ball bearing for shafts with a diameter of 280 mm. This open heavy-duty bearing from FAG has an outer diameter of 420 mm and a width of 65 mm. Manufactured from standard rolling-element bearing steel 100Cr6, the component primarily absorbs radial forces as well as moderate axial forces on both sides. It is manufactured to the standard tolerance class P0/PN or ABEC 1 for standardised industrial applications.

In which applications is the 6056 -M-C3 deep groove ball bearing used?

Heavy-duty industrial gearboxes and large rotating units in general mechanical engineering typically use the 6056 -M-C3 deep groove ball bearing as a fixed or floating bearing. The combination of solid bearing rings and robust rolling elements enables the bearing to withstand high loads at constant speeds. As the outer ring is designed without a flange or groove, the bearing can be fitted with a precise fit into cylindrical housing bores.

What function do the brass cage and the C3 bearing clearance fulfil in this bearing?

The solid brass cage, designated by the letter M, reliably guides the balls along the raceways even in the presence of vibrations or shocks. The increased radial clearance (C3) compensates for thermal expansion that may occur during continuous operation at higher temperatures. This ensures that the required operating clearance between the rolling elements and raceways is maintained if the shaft and housing heat up unevenly during operation. The permissible temperature range for the bearing components is from -30 to +200 degrees.
