R+W Antriebselemente GmbH
R+W - THE MKS MINIATURE BELLOWS COUPLING
For over 30 years, R+W Antriebselemente GmbH has been manufacturing couplings, torque limiters and shaft lines for the whole world from 0.05 Nm to 2000 kNm that could meet your needs. In addition to a wide range of products, we can also offer you special couplings totally adapted to your applications.
CLEARANCE-FREE AND EASY TO ASSEMBLE: MINIATURE BELLOWS COUPLINGS FROM R+W
The miniature bellows couplings (MK series) from R+W are suitable wherever torques from 0.5 Nm have to be transmitted and drilling diameters from one millimeter have to be achieved. With the current trend towards miniaturization, for example in medical technology, precision equipment construction, laboratory technology or micro-dosing pumps, this product plays an important role in a very rapidly growing market. Backlash-free miniature bellows couplings are precisely the convincing design solution within precision couplings for this segment.
- Structure: hubs with conical clamping rings and 4 ISO 4017 screws respectively
- Temperature range: -30 to +110°C
- Clearance: of the shaft-hub connection 0.01 - 0.025 mm
- Lifespan: miniature bellows couplings are very durable and maintenance-free if the technical instructions are followed.
