Twin Screw Extruders Plastic Roller Bearing T6AR3278 32X78X163.5mm Brass Cage

Twin Screw Extruders Plastic Roller Bearing T6AR3278 32X78X163.5mm Brass Cage

  Tandem roller bearings T6 AR3278 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 T6AR 3278 with size 30x78x163.5mm , the inner diameter:30mm, the outer diameter:78mm, the total height:163.5mm

Tandem Thrust Bearings

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 design allows the use of a high thrust capacity bearing in a small area. It was originally designed for a rotary swivel used on an oil drilling rig. Later these bearings were adopted by plastics and rubber manufacturers for use in single screw extruders utilizing 2 and 3 stage bearings. The tandem design enabled the extruder manufacturers to
increase the output of the machines without increasing the size of the
gearboxes.This allowed their customers to have a higher output machine without taking up more floor space. These bearings are used in twin screw extruders as well.Twin screw extruders have two parallel shafts very close to each other, making the use of the tandem thrust bearing essential. Some twin screw extruder designs use eight stage tandem thrust bearings.We manufacture two, three, four, six and eight stage bearings in both inch and metric
series. Bore sizes range from about 1 to 22 inches with corresponding outside diameters ranging from 3.5 to 42 inches. tandem thrust bearings are supplied to original equipment manufacturers and the aftermarket.

The bearing T6AR3278 32x78x163.5mm will use the following industry machine:

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.
