Tandem Thrust Bearing Application:
Rubber industry parallel twin-screw extruder,Deep drilling oil rig,Pipelay pulling machine,Screw press oil extraction machine
Mounting Tandem Bearings:
Tandem bearings are mounted with a loose F7 fit for the housing and f6 for the tandem bearing shaft. A loose fit is necessary to allow the axial shifting (deflection) of the washers, rings and sleeves. The seating surface of the adjacent structure (housing and shaft) should be designed to have a perpendicularity tolerance to DIN ISO 1101
and qualities IT4 to IT7(depending on the diameter range).
For the mating structure, care should also be taken to ensure that the contact diameter indicated on the delivery drawing is maintained. The contact diameter (support diameter) for the shaft shoulder may not be lower than the diameter indicated, and the contact diameter for the housing must not be exceeded.
Insufficient support will not only cause an unequal load distribution but also an increased washer deformation , which in turn will result in increased strain on the components. Since tandem bearings are thrust bearings that are not capable of supporting radial loads, it is advisable to provide sufficient radial support. One way to do this is to use needle roller bearings. This will allow potential shaft deflection and associated frictional losses to be reduced, especially in the case of continuous shafts where pinion and tandem bearing are on the same shaft and not separated by a gear coupling.
