As modern robots are developing towards light weight, robot bearings are one of its important matching parts. Because they need to be installed in a limited space, the bearings are required to be small in size and light in weight. The performance conditions such as performance, positioning speed, load, repeated positioning accuracy and working life have high requirements. Robot bearings must have the characteristics of high load, high speed, high precision, low friction torque and long life. According to the actual situation of various robot products on the market, the company strives to provide suitable robot bearings and solutions for customers from the aspects of raw material selection, heat treatment process improvement, bearing production and testing equipment upgrade, bearing internal structure design optimization, and lubricant grease selection. To meet customer requirements for bearings in terms of speed, quality, delivery time, noise level, etc.
