Product Description

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.

The tandem bearings provided by our institute has the following types: double rows, three rows, four rows, five rows, six rows and eight rows, we also provided bearings with shaft and sleeve barrel. Customers can have their own selections according to center distance of screws, space and load (Figure 1~3). We also accept the orders of other dimensions.


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 see Figure 1~3. 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 (Figure 4)
