Miniature Bellows Couplings

R+W Miniature Bellows Coupling - Series MK

BACKLASH FREE AND USER FRIENDLY: MINIATURE BELLOWS COUPLINGS FROM R+W

Where torques as low as 0.05 Nm are to be transmitted and shaft diameters as small as 1mm are to be connected, miniature bellows couplings (MK series) from R+W are the right choice. As a result of the trend toward miniaturisation - for example, in medical technology, laboratory equipment, and micro-pumps - this product plays an important role in a growth market.

Miniature bellows couplings address conflicting requirements regarding stiffness, with maximum stiffness in the direction of rotation, and very low stiffness in other directions while compensating for misalignment - for example, in rotary encoders, tachometers and small motor drives. This compensation for radial, axial and angular misalignment plays an important role in protecting the connected equipment and preventing damage to downstream components.
