4x20x77.5mm thrust cylindrical roller bearings factory tandem bearings with shaft

Tandem Thrust bearings are comprised of "stages" which include precision ground and matched thrust plates. These bearings also include compression sleeves separated by cylindrical roller assemblies. This design enables the Tandem Thrust bearings to provide a solution in a radial restricted envelope. The bearings are available in multiple stages, 2-8 to accommodate your design requirements. Depending on your preference, these bearings are available in a wide variety of sizes and options.

TandemThrust Bearings can receive heavy load in a limited space and support firmly in the direction of axis and last long with low frictional power. In addition, these bearings are moved by oil lubrication. Also thesetandem thrust bearings are used principally in gear boxes for single & twin screw extruders in the rubber and plastic industries.

Extruders are used in the processi
ng 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 gearboxesExtruders 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.
