The Axial Forces Are Supported By A four -Stage Tandem Bearing T4AR Combined With An Axial Cylindrical Roller Bearing  

application Tandem bearings have proven effective principally in gearboxes for single and twin screw extruders in the rubber and plastics industry.

Other possible applications include:

 deep hole drilling equipment

 friction welding machines.

T.AR tandem  tandem thrust bearing is a thrust bearing that supports load in a single direction:

It consists of two to eight thrust cylindrical roller bearings arranged in series, and has a middle ring. The elastic diaphragm system can evenly distribute the force to each thrust cylindrical roller bearing. The roller is a tried-and-tested cylindrical roller in the product catalog. Cylindrical rollers are guided by cages. Cages are made of brass, aluminum or nylon. Bearing rings and spacers are made of hardened steel. For high performance types, bearing rings made of high performance steel are used. The speed, permissible temperature range and design details of the T.AR series series thrust bearings can be found in the quotation drawing.

Tandem bearing F-50988.T4AR has the following structural types:

Basic type tandem bearing FIG. 2 is connected with the shaft ring, seat ring and roller cage assembly by elastic spacers. This type of bearing is separable structure, parts can be detachable, it must be carefully installed and disassembled in accordance with the numbering order provided by our company

FIG. 3 Serial bearing with shaft type of our company's product is a variant structure bearing. A shaft is threaded through the inner hole of the basic serial bearing, and the bearing is fixed on the shaft with an elastic lock ring. The bearing parts can not be separated, the overall loading and unloading when used, very convenient.

FIG. 4 shows that sleeve is covered on the outside of basic type tandem bearing, which is generally loaded and unloaded in use.
