R+W Antriebselemente GmbH
R+W - THE MINATURE BELLOWS COUPLING MK4
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 :
- Standard: with clamping hub and one side screw ISO 4762 respectively
- Optional (MKH): split clamping hub, both hub halves removable in one direction.
- Temperature range: -30 to +120°C
- Clearance: of the shaft-hub connection 0.01 - 0.05 mm
- Lifespan: miniature bellows couplings are very durable and maintenance-free if the technical instructions are followed.
- Material :
- Highly elastic stainless steel bellows
- Hub material: Al
- Technical characteristics :
- Rated torque: 0.5 - 10 Nm
- Rotation speeds up to 10,000 rpm
- > 10,000 rpm on finely balanced model
- Shaft diameter from 3 to 24 mm
- Special miniature bellows coupling solutions: such as other bore tolerances, keyways, special material and bellows possible at short notice.
- Properties of the miniature bellows coupling, model MK4:
- Play-free and torsionally rigid
- Compensation for misalignment
- Connection by force connection using clamping hubs
- For highly dynamic applications
- Low moment of inertia
