Tandem bearings consist of several axial cylindrical roller bearings arranged in line, A system of rings and washers matched to each other ensures that all stages of the tandem bearing are subjected to uniform load at all times irrespective of the ratio C/F. The rings and washers are made from hardened steel. Tandem bearings are predominantly fitted with standard
axial cylindrical roller and bearing assemblies.

Extruders are used in the processing of plastics in powder or granulate form, mixed with stabilisers, parting agents and any colourings and fillers; they are conveyed, compacted, degassed, homogenised and finally pressed through a die into profiled tooling. In order to apply the necessary forces correctly, very high demands are placed on the extruder gearboxes. Small centre distances, are present in certain extrusion processes. As a result, the gearboxes have high power levels and the screws are subjected to very high axial forces.
