Special tandem bearing for petroleum screw drilling tools T4AR2866 M4CT2866 28X66X107.5mm

 Special bearing for petroleum screw drilling tools T4AR2866 M4CT2866 28X66X107.5mm

Tandem thrust cylindrical roller T4AR2866 M4CT2866 bearings with size 28X66X107.5mm have the characteristics of small radial cross-sectional size, compact structure, large axial load capacity, uniform load of each row of rollers, wear resistance, low vibration noise and long life. They are parallel twin screw extruders. Ideal screw spindle bearing.

For tandem bearing T4AR2866 M4CT2866 please reference the picture:

Tandem bearings have the following structural types:
The basic type tandem bearing is to connect the shaft ring, the seat ring and the roller-cage assembly through the elastic spacer. This type of bearing is a separate structure, the parts can be disassembled, and it must be carefully installed and disassembled according to the numbering sequence provided by our company.
The tandem bearing with shaft is a modified structure bearing. A shaft is inserted in the inner hole of the basic tandem bearing, and the bearing is fixed on the shaft with an elastic lock ring. The bearing parts of this type are inseparable, and it is very convenient to install and dismount the whole bearing during use.

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. We also accept the orders of other dimensions.

Our team advantage:
We have 70 employees, with 10 experienced engineers and professional technicists. The most of Engineer from LYC and ZWZ brand factory, they had owned produce and design and after sales experienced to design the bearing.We can also design the drawing according to the bearing work condition to meet the customer requirement.

Manufacturing ability:
Equipped with advanced manufacturing CNC Machine and test instruments to insure the accurate tolerance , all bearings are of uniform marking and packing with superior quality, reasonable prices and perfect services. Meanwhile we can make the module to test the mounting hole.
Quality control:
All the bearing from the forging to assembly process,It will need to inspect step.For the bearing forging we will need to test the size and hardness and surface, for the lathe process and grinding process,first it will need to check by the worker ,and then the professional inspector will checking the size and accurate,The last step the monitor will inspect the size. It can insure zero defect.
Service:
It can calculate the load curve.
Can offer assembly drawing based on the bearing working condition
Can offer pre- sale ,sale and after sale service
