F-81657 eight stage cylindrical roller thrust bearings

Tandem bearing Description

Tandem Thrust bearings are also known as “multi-stage cylindrical roller thrust bearings”. Tandem Thrust bearings are comprised of "stages" which include precision ground, matched thrust plates and compression sleeves which are separated by cylindrical rollers assemblies. The design of the bearing is suitable for applications where radial envelope is restricted.

Tandem Thrust Bearings can receive heavy load in a limited space and support firmly in the direction of axis and last long with low frictional power. In addition, these bearings are moved by oil lubrication. Also these tandem thrust bearings are used principally in gear boxes for single & twin screw extruders in the rubber and plastic industries.

Multi-Stage cylindrical roller thrust bearings(Tandem bearings) has the characteristics of small radial cross section size/limited radial space, compact structure, large axial load capacity, each column roller uniform load/equal support of all the rows of rollers, wear resistance, small vibration noise and long operating life and other characteristics, is the ideal of parallel twin screw extruder screw spindle bearing. Users can choose two, three, four, five, six, seven or eight columns tandem bearings according to screw center distance, space and load etc. We also provided bearings with shaft and sleeve barrel as well as OEM type.

Tandem Bearings Type

1. Basic Type: The bearing 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 our guide book.

2. Shaft Type: The bearing is made by penetrating an axis through the inner bore of basic type bearing and fastening the bearing to the axis by locking collar/snap ring. The components of this type bearing are inseparable. Shaft type tandem bearing is variational structure of basic type.

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.
