R+W Antriebselemente GmbH
R+W THE MINIATURE BELLOWS COUPLING MK5
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 :
- 1 side with clamping hub with ISO 4762 screw
- 1 side clamping hub with ISO 4762 screw and backlash-free conical plug connector
- 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
- Conical clamping hubs and conical segment bellows side: Al
- Conical segment on the clamping hub side: fiberglass reinforced plastic sprayed onto the hub
- 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 20 mm
- For higher torques, the BK5 bellows coupling is better suited.
- Special miniature bellows coupling solutions: such as other bore tolerances, keyways, special material and bellows possible at short notice.
- Properties of the MK5 model miniature bellows coupling:
- Play-free and torsionally rigid
- Compensation for misalignment
- Easy assembly and disassembly
- Electrical and thermal insulation
- Low moment of inertia
