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 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 the further advantages of electrical and thermal isolation. 

OVERVIEW: R+W MINIATURE BELLOWS COUPLINGS

APPLICATION AREAS FOR R+W MINIATURE BELLOWS COUPLINGS

  • MKH miniature bellows couplings with split clamping hubs:
    can be radially mounted between two fixed shafts and stand out from the crowd as a result of their quick mounting and dismounting.
  • MKH miniature bellows couplings with clamping hubs:
    work in a rotationally stiff manner without backlash while also compensating for misalignment and creating a frictional clamping connection between shafts for highly dynamic transmission
  • BKL003 Ecoflex with clamping hub
    Backlash free, affordable and torsionally stiff miniature bellows couplings for basic torque transmission and misalignment compensation
  • FK1 MICROFLEX COUPLING
    Compact coupling made of polyamide and stainless steel for various small sized applications
