We manufacture two, three, four, six and eight stage bearings in both inch and metric
series. Bore sizes range from about 1 to 22 inches with corresponding outside diameters ranging from 3.5 to 42 inches. tandem thrust bearings are supplied to original equipment manufacturers and the aftermarket.
When using tandem bearings, the following recommendations should be adhered to:
1. Preload: 1% of the dynamic basic load rating. The dynamic basic load rating of each tandem bearing . Figures not listed will be provided by out institute on request.
2. Radial guidance: full complement cylindrical roller bearings or needle roller bearings can be used.
3. Eliminate tilting: the supporting parts must be machined to eliminate any tilting.
4. Mounting tolerances: recommended the following mounting tolerances: shaft f6 and housing bore F7.
5. Lubrication: tandem bearings must always be lubricated by oil circulation.

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.
