Tandem Thrust Bearings

The bearing consists of a series of thrust plates and roller assemblies with compression sleeves separating the stages. The component design and overall match grinding make this bearing unique. The design of the sleeves, along with the precision match grinding of the components, allows the load to be equally applied through the stages of the bearing.

Tandem thrust bearings are designed to be used in horizontal shaft applications (extruder gear drives) and it is essential that a sufficientthrust load be applied to prevent roller slip. Typically, the minimum load required is expressed as a ratio of the bearing’s dynamic load rating (C)

to the applied load (P). Loads representing C/P > 12 must be avoided and loads where C/P falls between 8 and 12 should be avoided.

The tandem design allows the use of a high thrust capacity bearing in a small area. It was originally designed for a rotary swivel used on an oil drilling rig. Later these bearings were adopted by plastics and rubber manufacturers for use in single screw extruders utilizing 2 and 3 stage bearings. The tandem design enabled the extruder manufacturers to increase the output of the machines without increasing the size of the gearboxes.This allowed their customers to have a higher output machine without taking up more floor space. These bearings are used in twin screw extruders as well.Twin screw extruders have two parallel shafts very close to each other, making the use of the tandem thrust bearing essential. Some twin screw extruder designs use eight stage tandem thrust bearings.We manufacture two, three, four, six and eight stage bearings in both inch and metricseries. 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.
