Tips: Diaphragm coupling advantages
The diaphragm coupling has a simple structure and high reliability. It is suitable for high-speed, high-power, high-temperature and corrosive environments. It has great axial and angular compensation, good anti-misalignment, and has vibration absorption and vibration isolation functions. The coupling has no noise, zero clearance, constant speed, no need for lubrication. The additional load acting on the connected equipment is small, and the diaphragm coupling is easy to install, use and maintain.
12mm to 25mm diaphragm coupling rated torque 25N.m, diameter 56mm x length 45mm, high speed operation, low noise, accurately assembled using high-strength, corrosion-resistant fasteners and have a long service life time, designed for connecting servo motors and stepping motors.
