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.

JinHang Precision bearing offer Tandem thrust cylindrical roller
T3AR3278 M3CT3278 bearings have the characteristics of small radial
cross-sectional size, compact structure, large axial load capacity,
uniform load of each row of rollers, wear resistance, low vibration
noise and long life. They are parallel twin screw extruders. Ideal
screw spindle bearing.
The tandem bearing including two, three, four, five, six, seven or
eight rows of tandem bearings in the company's sample according to
the screw center distance, space and load size. The company also
accepts tandem bearings of sizes and structures other than the
sample.
