diaphragm couplings for elevator systems

Outstanding Diaphragm Couplings for Elevator Systems

Engineered for the highest level of performance and efficiency, our diaphragm couplings for elevator systems are the epitome of cutting-edge technology and superior design. These couplings are specifically designed to offer seamless connectivity and optimal operation of elevator systems.

Design and Operational Principles

Diaphragm couplings are designed with a flexible element that connects two shaft ends. This design enables the couplings to compensate for all types of shaft misalignment, providing a smooth and efficient operation. The operational principle of diaphragm couplings relies on their ability to transmit torque through the flexible diaphragms, thus reducing vibration and increasing the lifespan of the elevator system.


Benefits of Diaphragm Couplings and Selection Criteria

Diaphragm couplings offer numerous advantages, including high torsional stiffness, zero backlash, and the ability to function under high-speed conditions. When selecting a diaphragm coupling, consider factors such as torque requirements, shaft size, misalignment capabilities, and environmental conditions.

Installation and Maintenance


Our diaphragm couplings are easy to install and require minimal maintenance. Regular inspections for wear and tear, and occasional lubrication are sufficient to ensure their longevity.
