Where mining machinery and engineering machinery are active, most of them are mining sites far away from ordinary human life, such as mountain areas and desert areas. Sometimes they even work 2000 meters underground. There are many kinds of such machinery, from mineral crushing machinery to cutting machinery, screening machinery, loading machinery, conveying machinery, etc., all of which operate continuously 24 hours a day. The failure of any of these machines will have a great impact on the production at the mining site. Moreover, due to the recent large-scale machinery, the maintenance operation has become very difficult.

Therefore, in terms of the service environment of bearings, there are many very harsh conditions for bearings, such as "heavy load+impact load", "light load+high-speed rotation", and "heavy load+low-speed rotation". Therefore, the bearings that users desire are products with robustness, durability and high reliability that can withstand these harsh working conditions.

In order to meet these needs of users, we have been integrating our core technologies, namely material technology, lubrication technology, analytical technology and advanced bearing design technology, and committed to relevant research and development. As a result, the goal of providing products that greatly exceed the "long life and high limit speed" level of the previous bearings has been achieved, contributing to improving the production efficiency of mining sites in harsh environments and reducing maintenance costs for customers. In addition, it also provides new solutions corresponding to environmental requirements.

Mining machinery and engineering machinery are in operation at all mining sites. Under the premise of convenient maintenance, the bearings used in these equipment mainly use ISO standard bearings. Therefore, a standard bearing with high performance has been developed to make contributions to the mining machinery and construction machinery industry.

This kind of bearing, due to the adoption of a new type of cage, special surface processing and the selection of advanced materials, can greatly improve the bearing load capacity, and also achieve a long life of the bearing.

Cylindrical roller bearing EM series

A one-piece roller guide turning cage with good overall performance is developed for this bearing, and at the same time, the roller size and the number of rollers are increased. As a result, the serialization of cylindrical roller bearings with high bearing capacity in the new era with high performance and long life characteristics has been completed.

In the future, we will continue to promote research and development with the goal of maintaining the manufacturing level of * * high-performance bearings.
