Product description

Made of POM, a plastic material with good mechanical strength. For compensation of a misalignment of axes between stirrer shaft and stirring drive of up to 10 mm. Powerful transmission of max. 300 Ncm and suitable for a speed of up to 1200 rounds per minute and for both left- and right-handed rotation (except for version with female thread GL 10).
Different versions for assembly of glass, metal or PTFE coated shafts by means of a clamp screw to accept shafts with O.D. 4.0 mm, 6.5, 8.0 or 10.0 mm. An additional reducing sleeve for O.D. 6.5 / 8.0 mm is included in delivery.

The chuck adaptor is fixed directly in the drill chuck of the stirring drive and can be shortened if necessary.
