T7AR1880 M7CT1880 Tandem bearing series 7 row Bearings for plastic extruding machine 18*80*200

T7AR1880 M7CT1880 Tandem bearing series 7 row Bearings for plastic extruding machine 18*80*200mm

Thrust cylindrical roller bearing T7AR1880 M7CT1880 series bearings with size 18*80*200mm 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.

The tandem bearing T7AR1880 M7CT1880 application as following:

Tandem thrust cylindrical roller bearings have a limited radial cross-section, super axial load capacity, long-term working life and minimum friction loss, so they are obtained in the parallel twin screw extruder gear transmission box in the rubber and plastics industry Very successful application. It will also be popularized and applied in other mechanical equipment.

Tandem bearings T7AR1880 M7CT1880 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.

Tandem bearing with sleeve, sleeve is sleeved on the outside of the basic tandem bearing.

When using tandem bearings T7AR1880 M7CT1880, 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 . 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.

6. if you have the technology problem, Please contact us, we can offer the solve the solution for you.

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
