The places where mining machinery and engineering machinery are active are mostly mining sites away from ordinary human life, such as mountains and deserts, and sometimes even work underground 2,000 meters. These types of machinery range from mineral grinding machines to cutting machines, screening machines, loading machines, conveyors, etc., all of which operate continuously 24 hours a day. No matter which kind of machinery has failed in these machines, it will greatly affect the production at the mining site, and the maintenance work has become very difficult due to the recent large-scale machinery.

       Therefore, in terms of the use environment of the bearing, "heavy load + impact load", "light load + high speed rotation", "heavy load + low speed rotation" and the like are very harsh conditions for the bearing. Therefore, the bearings that the user desires are products that are resistant to the harshness, durability, and reliability of these harsh conditions.

       In order to meet these needs of users, Shanghai Hangu Precision Transmission Technology Co., Ltd. has always integrated its core technology, namely material technology, lubrication technology, analytical technology and the most advanced bearing design technology, and is committed to relevant research and development. As a result, it has achieved the goal of providing products that significantly exceed the "long life and high limit speed" levels of conventional bearings, and contributes to improving production efficiency and reducing maintenance costs at the mining site in harsh environments. In addition, our company also provides new solutions for environmental protection requirements.

       NSK's performance and innovative technology
       Mining machinery and construction machinery are in operation at mining sites around the world. The bearings used in these equipments mainly use standard bearings of ISO specifications, taking into account the convenience of maintenance. Therefore, Shanghai Hangu Precision Transmission Technology Co., Ltd. can provide the world's highest performance standard bearings in time to contribute to the mining machinery and engineering machinery industry.

       HPS spherical roller bearing
       This type of bearing, thanks to the new cage, has been specially machined and selected with the most advanced materials, the bearing load capacity has been greatly improved, and the long life of the bearing has been achieved.

       Cylindrical Roller Bearings EM Series

       NSK Bearings of Japan developed a one-piece roller-guided cage with good overall performance for this type of bearing, and at the same time realized an increase in roller size and an increase in the number of rollers. As a result, the high-performance and long-life characteristics of the new era of high-capacity cylindrical roller bearings have been serialized.
