Single Screw Extruders Gearbox Shaft Bearing T6AR3073 30x73x182mm Six Stages Roller

 Single Screw Extruders Gearbox Shaft Bearing T6AR3073 30x73x182mm Six Stages Roller

Tandem roller bearings T6AR 3073 consist of several axial cylindrical roller bearings arranged in line, A system of rings and washers matched to each other ensures that all stages of the tandem bearing are subjected to uniform load at all times irrespective of the ratio C/F. The rings and washers are made from hardened steel. Tandem bearings are predominantly fitted with standard axial cylindrical roller and bearing assemblies. The thrust cylindrical roller bearing T6 AR3073 with size 30X73X182mm , the inner diameter:30mm, the outer diameter:73mm, the total height:182mm

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 metric
series. 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.
