Our ultra thin wall equal cross section bearings and crossed roller bearings are precision rotary components applied in industrial collaborative robot joints. The equal cross-section thin wall ball bearings maintain constant cross-section with enlarged bore size, saving installation space and reducing weight for robotic arms. The product range includes deep groove ball, angular contact ball and four point contact ball thin wall bearings, which can withstand radial, axial and tilting moment loads. Crossed roller bearings feature high rigidity and strong anti-tilting performance for heavy load robot joints. Made of high purity bearing steel or stainless steel, all bearings adopt precision grinding process to realize low friction torque and high rotation accuracy. These bearings serve as key parts for cobot wrist, forearm, shoulder and base joints, widely used in flexible automation assembly and material handling scenarios.
