The combination of two worm gearboxes provides very low efficiency, however the fact that substantial reduction in speed can be obtained in an extremely reduced space makes this solution very interesting and sometimes irreplaceable. Combined
worm gearboxes are available in series: KX, XX and KK.
The KX and KK series are available for IEC version only.
The XX series is available in the XXA version with shaft and in two versions with motor coupling: XXC (compact) and XXF (with bell and joint).
The hollow shaft is supplied as standard.
