Bellows couplings - BK

Torsional stiffness and elasticity
For applications from 15 to 10.000Nm
For shaft diameters from 10 to 180mm

• For very dynamic servo shafts
• No backlash
• Favorable mounting versions, mounting versions without connection to the dowel
• Universal installation
• Possibl rotational speeds up to 50.000 rpm
• Displacement equalization
• No wear
• Small mass moments of inertia

AREA OF APPLICATIONS OF BELLOWS COUPLINGS BK:

For these couplings, which have no backlash and are torsionally rigid, the field of application for highly dynamic sevo shafts is: machine tools, NC-milling machines, woodworking machines, packaging machines, stone processing machines, engraving machines, automation devices, printing machines, sheet metal forming machines, industrial robots, textile machines, ginning machines and many others.
