PVC Extuder Gearbox Thrust Cylindrical Roller Bearing T6AR2390A2 23*90*213mm

PVC Extuder Gearbox Thrust Cylindrical Roller Bearing T6AR2390A2 23*90*213mm

 Tandem roller bearings t6ar2390a2 consist of several axial cylindrical roller bearings arranged in line, A system of rings and washers matched to each other ensures that all stages of the tandem bearing are subjected to uniform load at all times irrespective of the ratio C/F. The rings and washers are made from hardened steel. Tandem bearings are predominantly fitted with standard axial cylindrical roller and bearing assemblies. The thrust cylindrical roller bearing T6 AR2270A2 with size 23X90X213mm , the inner diameter:23mm, the outer diameter:90mm, the total height:213mm

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.

Twin Screw Extruder Gearboxes
Twin Screw Drives offer the dual shaft counter rotating Extruder gear units. The twin screw extruder gearboxes both co-rotating and counter rotating variants are available. The gearboxes of the are designed for a wide range of applications and requirements, starting from the typical applications for revolutions of 290 to max. 890 rpm. to where lower revolution rates from 23 to max. 195 rpm. The range is available for various centre distances, please call to confirm. On request, also bigger versions can be built.

The bearing consists of a series of thrust plates and roller assemblies with compression sleeves separating the stages. The component design and overall match grinding make this bearing unique. The design of the sleeves, along with the precision match grinding of the components, allows the load to be equally applied through the stages of the bearing.
Tandem thrust bearings are designed to be used in horizontal shaft applications (extruder gear drives) and it is essential that a sufficientthrust load be applied to prevent roller slip. Typically, the minimum load required is expressed as a ratio of the bearing’s dynamic load rating (C)
to the applied load (P). Loads representing C/P > 12 must be avoided and loads where C/P falls between 8 and 12 should be avoided.

The tandem bearing  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.

High torque and high speed output rate feature in our range of Twin Screw Extruder Gear Box .

To work under heavy loading force , the high level dissipation and oil lubrication system are provided with. The axial roller type swivel thrust with the thrust bearing coupled in tandem way support the axial thrust.
