F-53507.T6AR Thrust Cylindrical Roller Bearing For PVC Extruder Machine

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

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

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.

How to Mount Tandem Bearings:

Tandem bearings are mounted with a loose F7 fit for the housing and f6 for the
tandem bearing shaft. A loose fit is necessary to allow the axial shifting (deflection) of the washers, rings and sleeves. The seating surface of the adjacent structure (housing and shaft) should be designed to have a perpendicularity tolerance to DIN ISO 1101 and qualities IT4 to IT7
(depending on the diameter range). For the mating structure, care should also be taken to ensure that the contact diameter indicated on the delivery drawing is maintained. The contact diameter
(support diameter) for the shaft shoulder may not be lower than the diameter indicated, and the contact diameter for the housing must not be exceeded. Insufficient support will not only cause an unequal load distribution but also an increased washer deformation (washers GS 0 and WS 0), which in turn will result in increased strain on the components.
