Parallel Line Metal Shaft Coupling 17mm 12mm 10mm Shaft Coupler For Stepper Motor
GI Aluminum Alloy Parallel Line Clamping Coupling
Products Features
Diaphragm coupling has obvious damping effect, no noise, no wear, long life, suitable for working in high temperature (-80+300) and harsh environment, moving in the case of shock and vibration, high transmission efficiency, can be up to 99.86%. It is especially suitable for medium and high-speed high-power transmission, with simple structure, light weight, small volume, and convenient assembly and disassembly. It can be assembled and disassembled without moving the machine, without lubrication, and can accurately transmit the rotation speed, with no slip and fast rotation.
GI Aluminum Alloy Parallel Line Clamping Coupling has the following advantages:
>Integrated structure, the overall use of high-strength aluminum alloy materials
>Elastic action compensates radial, angular and axial deviation
>No gap shaft and sleeve connection, suitable for forward and reverse rotation
>Designed for encoder and stepper motor
>Fastening method of set screw
