There are many types of rolling bearings used in plate rolling mills, and each type of bearing has its own suitable application occasions. In actual work, there are many cases of bearing failure or early damage due to improper bearing selection. Therefore, the selection of bearing type and the correct installation and use play a […]
When the motor bearing temperature is not significantly higher than the motor base temperature, the overall heating of the motor bearing is not the main component of the motor heating, and the temperature distribution at this time is in line with the normal temperature distribution. Therefore, from the perspective of temperature distribution, the possibility of […]
The rolling mill bearing is an important part of the rolling mill stand. Its main function is to support the rotating roll, bear the rolling force transmitted by the roll, and maintain the correct position of the roll in the stand. The working conditions of rolling mill bearings are very bad and are affected by […]
Generally speaking, the amount of grease added for the supplement lubrication of horizontal internal rotating motor shall be: -For bearings without intermediate fill holes: G = 0.005BD Where D is the outer diameter of the bearing and B is the bearing width, in mm. These two data can be retrieved from the bearing type record. […]
The failure of the work roll bearing of the cold rolling mill causes the rolling line to stop, reducing the operating rate of the rolling mill, and reducing the output; causing damage to the bearing, the bearing seat and its accessories. Therefore, while absorbing the successful experience of other manufacturers, combined with the actual working […]
Railway rolling stock Bearings Railway rolling stock bearings refer to bearings used in locomotives and vehicles. Bearings on locomotives include axle box bearings, traction motor bearings, transmission system bearings, bearings of the power unit and bearings of the cooling system, etc. The bearings in railway vehicles are mainly axle box bearings, and passenger car axle […]
With the increasing maturity of offshore equipment technology, large cranes in the offshore industry have developed to super-large size and super-large tonnage, and the supporting slewing bearing diameter is more than 10 m. The slewing bearing structure of this diameter section is mostly split. Its advantage is that it is easy to transport, store and […]
Installation of rolling mill bearings The service life of rolling mill bearings is not only related to the quality of the bearing, but also closely related to its installation and use. To this end, attention should be paid to the technical requirements for bearing installation, and the relevant operating procedures should be followed. 1. Preparation […]
The market requirements for various mechanical devices and instruments using rolling bearings have become increasingly stringent, and the conditions and performance required for bearings have become increasingly diversified. In order to select the most suitable bearing from a large number of structures and sizes, it is necessary to study from various angles. When selecting a […]
The eighteen-high rolling mill bearings adopt double-row needle roller bearings. When the copper foil is rolled at a high speed of 600m/min, the bearing speed reaches 3550r/min. The working conditions of the bearing are extremely bad, and improper assembly is prone to burns and scratches on the bearing surface. Needle roller fracture, wear, needle roller […]
