Where torques from 0.05 Nm need to be transmitted and shaft diameters from 1 mm need to be coupled, the MK series of miniature bellows couplings from R + W Couplings are the right choice. As a result of the trend towards miniaturization - for example in medical technology, laboratory equipment and micro pumps - this product plays an important role in a growth market. Backlash-free miniature bellows couplings are the design solution among the precision couplings for equipment with limited dimensions.
The stainless steel bellows is the central part and compensation element. The correct selection is based on practical requirements, for example the amount of torque to be transmitted and the degree of alignment to be compensated. Miniature bellows couplings meet conflicting stiffness requirements, with maximum stiffness in the direction of rotation and very low stiffness in other directions, while the misalignment must be accommodated - for example, in rotary encoders, tachometers and small motor drives. Correcting this radial, axial and angular misalignment plays an important role in protecting the connected equipment and preventing damage to components. These miniature bellows couplings are also backlash free and offer quick and easy installation, with the benefits of electrical and thermal insulation.
