    Tandem bearings offer an optimum solution wherever the following requirements apply:
    ■ small radial design envelope
    ■ high axial forces
    ■ long operating life
    ■ low frictional energy.
    Tandem bearings have proven effective principally in gearboxes for single and twin screw extruders in the rubber and plastics industry.
    Other possible applications include:
    ■ deep hole drilling equipment
    ■ friction welding machines.

    Plastic extruder machine


    Application of tandem bearings
    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.
