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 miniaturization – for example, in medical technology, laboratory equipment, and micro-pumps – this product plays an important role in a growth market. Zero backlash miniature bellows couplings are the convincing design solution among precision couplings for size-reduced equipment.
MISALIGNMENT COMPENSATION, RELIABLE OPERATION, MAXIMUM PRECISION: NO PROBLEM WITH MINIATURE BELLOWS COUPLINGS
The central component and compensating element (as in every metal bellows coupling) is the metal bellows itself, formed from stainless steel tube. Proper selection is based on practical requirements, for example, the amount of torque to transmit and the degree of misalignment to compensate for. 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.
EASY INSTALLATION AND ZERO MAINTENANCE: THE FLEXIBLE R+W PRODUCT RANGE OF MINIATURE BELLOWS COUPLINGS
Available in a multitude of different connection options, including set screw hubs, split clamping hubs, conical clamping ring hubs, and models with mechanically expanding mandrels for hollow shaft connections, the MK series is suitable for a wide variety of applications. Two-piece plug-in designs are also available for even easier installation. These are also backlash-free and offer quick and easy installation, providing further advantages of electrical and thermal isolation.
