Shaft couplings connect two shafts and transfer power or motion between them. They are used to compensate for minor misalignments, reduce vibrations, and protect system components from overload. There are various types of shaft couplings, such as rigid, elastic, and torque-limiting couplings, widely used in industries, robotics, and power transmission solutions.
High-precision metal bellows couplings are typically used in applications requiring extremely accurate positioning and dynamic motion. Common applications include servo motor drives, medical devices, and more.
Features:
High-precision metal bellows couplings designed for light and ultra-light applications, such as laboratory equipment.
Features:
Elastomer couplings are part of the broader category known as jaw couplings. The coupling consists of separate components, namely hubs and an elastomer element positioned between the hubs.
Features:
Robust R+W disc couplings transmit torque through a friction-based disc pack, avoiding stress concentrations, backlash, and micro-movements typically caused by shoulder bolts. The design is exceptionally torsionally stiff and durable. R+W disc couplings effectively compensate for shaft misalignments and are ideal for heavy-duty industrial power transmission applications, such as paper machines, steel mills, generators, pulp handling equipment, and compressors.

The purpose of a shaft coupling is to connect two shafts and transfer power or motion between them. It compensates for minor misalignments, dampens vibrations, and protects the machinery from overload or improper loads.
There are several types of shaft couplings, including rigid couplings, flexible couplings, torque limiters, and slip couplings. The selection depends on the application requirements, such as precision and the nature of the load.
The correct choice is based on the shaft diameters, the power to be transmitted, the operating environment (e.g., temperatures, humidity), rotational speed, and the required flexibility or rigidity. It is also essential to consider shaft misalignments.
Yes, many shaft couplings, especially elastic or flexible models, are designed to dampen vibrations and shocks, protecting other system components and extending their lifespan.
The maintenance interval depends on the type of coupling and operating conditions. Most shaft couplings do not require regular maintenance, but models requiring lubrication should be checked according to the user manual. Regular inspection of shaft alignment and the condition of the coupling helps extend its lifespan.
