Power transmission technology is the power source of this changing world. Deeper knowledge, more advanced material technology and more powerful computing power all contribute to the development of gear transmission technology and products in various stages, and make the size of gears smaller and smaller. Roller bearings have always contributed to this advancement in power transmission technology. Metallurgical Technology, internal geometry design and lubrication technology have greatly improved the bearing life and reliability of operation. Our engineers are always committed to improving the functional density and performance of gear drives. Two major improvements have greatly enhanced our ability to serve the market: 1. A significantly expanded metric, inch bearing product line 2. In the original equipment and after-sales market has a full range of bearing products. Including tapered roller bearings, self-aligning roller bearings, cylindrical roller bearings, needle roller bearings, ball bearings and thrust bearing gear reducers are a combination of speed reduction motors and large speed reducers. Without coupling and adapter, compact structure. The load distribution in the planet gear, therefore the bearing capacity is higher than the ordinary helical gear reducer. To meet the needs of small space high torque output. Widely used in large mines, iron and steel, chemical industry, ports, environmental protection and other fields. And K, R series combination can get more speed ratio.
