Product Description
The R+W MK2 miniature bellows coupling delivers precise, backlash-free torque transmission and high torsional rigidity for demanding motion control applications. Designed with precision clamping hubs and a durable metal bellows, the MK2 effectively compensates for shaft misalignment while maintaining exceptional positioning accuracy and repeatability. Its compact design, low moment of inertia and maintenance-free operation make it an excellent choice for servo systems, automation equipment, medical devices and precision machinery.
