Stirrer Couplings
These stirrer couplings are manufactured from POM, a mechanically hard, light plastic.
The power is transmitted by a completely innovative construction with internally fitted stainless steel balls.
Advantages
- High power transmission of up to 3 Nm
- Easy assembly of the stirrer shafts in a Ø 8 mm and Ø 10 mm holder (compression fitting)
- Extra-long mounting trunnion with Ø 10 mm, 8 mm external hex and a length of 90 mm, generates space (length can be shortened by the user)
- Temperature resistance -20…+110 °C, without stress
- Light but high-strength design
- Extremely low centrifugal force as a result of the low weight
- Suitable for glass, metal or PTFE-sheathed stirrer shafts
- Independent of the direction of turn
- Design is free of any play (no oscillation or resonance)
- Suitable for rotational speeds of 1,200 rpm

Bellows couplings
Our flexible stirrer shaft extensions are suited for the bridging of longer distances between the stirrer drive and stirrer lead-through.
They are made up of bellows couplings and stainless steel shafts.
