Features of Hollow Rotary Actuator

- Apr 04, 2019-

The Hollow Rotary Actuator adopts a brand-new rotary load device, which combines high transmission efficiency, high precision, high rigidity and high cost performance. It combines the advantages of servo hydraulic motor, cam splitter and DD motor, achieved a balance among these products.


Compared with other similar transmission positioning products, it can not only meet the servo hydraulic motor can not do - the direct load on the load, but also make up for the lack of the angle of the splitter can not be achieved - to achieve the positioning of any angle, Accuracy is comparable to DD motors, but the cost is much lower than DD motors. Equipped with servo motors and stepper motors, it is perfectly suitable for your requirements for circumferential positioning control.


The Hollow Rotary Actuator produced by Guangdong Saini Intelligent Equipment Technology Co., Ltd. adopts cross roller bearing and tapered roller bearing structure, which has high accuracy and large load capacity. The adoption of the top spiral bevel gear and the optimized design of contact tooth surface makes the even load and allow high torque output. When it combined with planetary reducer or right angle reducer, the gear ratio shall become bigger up to 1:180. Gears are made of high strength carburizing alloy steel and the hardness of the tooth surface after carburizing can reach HRC60±2°.


Saini Intelligent supplies multiple options for clients, GSN series, including table size 60, 85, 130, 200 and 280mm. GSB series contains table sizes 60, 100, 130, 200mm.
