Product Detail

Description:

The screw thread coupling consists of two hubs and a thin-walled metal tube, which are welded or bonded together. Stainless steel and nickel are the most commonly used metal tube materials, although many other materials are available. The nickel tube is finished by electrodeposition. This method first machined the solid mandrel into a corrugated shape, using nickel plating on the mandrel, and then the mandrel was chemically dissolved to produce the nickel screws. This method can control the accuracy of screws wall thickness and get thinner wall thickness than other methods. This thin-walled screw gives the coupling high sensitivity and rapid response, making it ideal for use in very small and precise instrument applications.


Feature:

>Integrated structure, the overall use of high-strength aluminum alloy materials

>Elastic action compensates radial, angular and axial deviation

>Spring design, with buffer effect

>Special design for encoder, micro motor

>Fastening method of set screw
