Twin Extruder Shaft Drives Use Thrust Roller Bearings TAB-040082-201
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 TAB-040082-201 are designed to be used in horizontal shaft applications (extruder gear drives) and it is essential that a sufficient thrust 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. TAB-040082-201 is two stages thrust roller bearing with inner dia:4 inch size,outer dia diameter:8.2515 inch size, the height:7.062 inch size

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.

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.
