What are the materials of bearings of roller conveyor line?

1. Cast steel or cast aluminum is used for the data of side hanging bearing seat.

2. According to the position and function of the device, the head bearing and the tail bearing follow the side bearing.

(1) Head bearing: it is mainly composed of centripetal thrust bearing, bearing seat, bearing cover, oil ring and other parts. It is installed at the discharge end of the head and suffers radial force and axial force. Therefore, the bearing should adopt centripetal thrust bearing.

(2) Tail bearing: it is installed at the tail feeding end and only suffers radial force. It adopts centripetal spherical bearing with simple structure.

(3) beside bearing: the conveyor roller of the screw shaft above 3 meters, in order to avoid twists and turns of the screw shaft, should be installed beside the bearing, beside the bearing individually take the suspension structure, and its transverse size should be as small as possible, so as not to cause material blockage.

3. Hanging bearings are divided into M1 rotating hanging bearings and M2 sliding hanging bearings.

(1), M1-rotary hanging bearing: adopt 80000 type sealed bearing, bearing cover has a dustproof sealing structure, commonly used in not easy to refueling, not refueling or oil is contaminated with materials, sealing consequences are good, bearing life is long, conveying material temperature is not greater than 80℃. The reversing roller is suitable for machinery, metallurgy, mining, port wharf, chemical medicine, cement building materials, iron and steel, coal and other fields. It is the driving device of all kinds of mobile belt conveyor, and can also be used for some fixed belt conveyor.

(2),  M2- sliding hanging bearing: cloth dustproof sealing device, bearing material has cast copper tile, alloy wear-resistant cast iron, copper foundation ink less oil lubrication tile, but individual powder metallurgy. Commonly used in conveying material temperature is relatively high place. The important parts and components of the drum system. The roller can effectively improve the operation of the conveying system, protect the metal roller from wear, prevent the conveyor belt from slipping, so that the roller and belt synchronous operation.

4. The head and tail bearings are moved to the outside of the shell, and the hanging bearings beside them are sliding bearings, with multi-layer sealing and matching sealing skills, and the bearing has a long service life.

5. It is not necessary to move the helix when removing the hanging bearing, and the hanging bearing may be lubricated without removing the cover plate.
