T8AR

The Axial Forces Are Supported By A 8 -Stage Tandem Bearing T8AR Combined With An Axial Cylindrical Roller Bearing  

application 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.

Design of bearing layout:

When T.AR series thrust bearings are used to design the thrust bearing arrangement of gearbox, many factors must be considered in the structural design.

F-80134.T8AR  tandem bearing preload:

T.AR series thrust bearings in series must bear preload of 1% of basic rated dynamic load. As a result, a minimum load can be provided to avoid skidding damage during no-load operation. In addition, it can ensure that the stiffness is within the linear range of the characteristic curve. The positioning of bearings with respect to the second shaft (the cochlear shaft) is simplified.

F-80134.T8AR  Tandem bearing load:

The common loads during the operation of extruders form the design basis of T.AR series series thrust bearings. The maximum axial load Fa max series thrust bearing has been specified in the quotation drawing. The bearing is not allowed to exceed the load during operation.

Tandem bearing F-80134.T8AR deformation:

For twin-screw extruders, the engagement between the screws must be ensured throughout the working rangeProcess gap. The deformation of the T.AR series series thrust bearing must be observed together with the second thrust bearing and matched with it. This is especially important when bearings of different designs are used on the two output shafts.
