R+W - BELLOWS COUPLING BK1
BACKLAY-FREE, TORSIONALLY RIGID AND ULTRA-PRECISE: METAL BELLOWS COUPLINGS FROM R+W
High-precision metal bellows couplings are used in all applications that require precise positioning: medical technologies, test benches, wind turbines or ultra-dynamic servo axes in machine tools, woodworking machines, manufacturing machines. packaging, etc. As a leading supplier, R+W strives to continually expand its range of metal bellows couplings for various applications in the most diverse sizes and designs.
MODE OF OPERATION: METAL BELLOWS COUPLINGS
Metal bellows couplings are particularly suitable for direct drives. The typical metal bellows is the key element of this coupling. It compensates for axial and angular misalignments for low restoring forces. The backlash-free, torsionally rigid metal bellows couplings ensure precise positioning of the drive unit and can be used in ultra-dynamic applications up to over 10,000 rpm on a finely balanced model.
- Structure :
- Each hub with 6 to 8 metric threads
- Centering of the assembled parts will be easy thanks to internal and external adjustment
- Other fitting diameters and circular holes possible on request
- Temperature range: -30 to +100°C
- Backlash: Absolutely backlash-free thanks to a tight, force-bonded connection and a proven principle.
- Lifespan: metal bellows couplings are very durable and maintenance-free if the technical instructions are followed.
