F-53507.T6AR thrust cylindrical roller bearing for PVC extruder machine

F-53507.T6AR f-53507.t6ar bearing specification as following:

Tandem roller bearing structure :
Tandem 2 rows(T2AR), Tandem 3 rows(T4AR), Tandem 6 rows(T6AR), Tandem 7 rows(T7AR), Tandem 8 rows(T8AR)* Tandem thrust bearings are produced by only through orders

Tandem thrust cylindrical roller Bearings Type
1.Multi-stage cylindrical roller thrust bearing (basic type) adopts elastic spacer to connect the shaft washer,housing washer, roller and cage assembly.
The components of this Thrust Bearings are demountable. The user should assemble or dismount
the bearing meticulously according to numeral order we provide.
2. Multi-stage cylindrical roller thrust bearing (shaft type) is made by penetrating an axis through the inner bore of basic type multi-stage cylindrical roller thrust bearing and fastening the bearing to the axis by locking collar.
The components of this type of cylindrical roller thrust bearing are inseparable.
3. Multi-stage cylindrical roller thrust bearing (sleeve type) locking collar is made by covering a sleeve to the external of the basic type multi-stage cylindrical roller thrust bearing.It is also inseparable,and is assembled and disassembled as a whole.
Multi-Stage cylindrical roller thrust bearings(Tandem bearings) has the characteristics of limited radial space, high axial forces, equal support of all the rows of rollers and long operating life, and is the ideal spindle of parallel screw extruder.

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.
