Description
Plastic double universal joint, Ø 10 mm, for metal shafts is a connecting element designed to compensate angular or axial misalignment between a stirrer drive and the stirring shaft. With an outer diameter of 10 mm and a maximum torque rating of 1,3 Nm, this double Cardan joint provides reliable power transmission in laboratory stirring setups where perfect shaft alignment cannot always be guaranteed. The plastic construction offers a lightweight solution that protects both the drive unit and the metal shaft from excessive mechanical stress during continuous operation. Supplied as a single piece with a net weight of 0,127 kg, the joint is intended for straightforward integration into existing stirring assemblies. Manufactured by Rettberg, it belongs to the range of stirrer couplings and quick-connect couplings used in chemical and pharmaceutical laboratories. Typical applications include overhead stirrers, reaction vessels and process development equipment where flexible yet controlled torque transfer is required. The component supports smooth rotation while accommodating minor offsets, helping to extend the service life of shafts and bearings in everyday laboratory use.

Questions about Stirrer coupling clamp, Ø 10 mm, double universal joint, plastic,
What is this article?
Stirrer coupling clamp, Ø 10 mm, double universal joint, plastic, is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Stirring shafts, propellers & impellers, inside Stirring, shaking & mixing, in Instruments de précision.
A shaft, a propeller or an impeller is the wetted end of an overhead stirrer. The diameter and the pitch decide whether the liquid turns over. The material, stainless steel or PTFE, decides what the liquid may be. The chuck size has to match the stirrer.
Stirring keeps a mixture uniform or helps a solid dissolve. A magnetic stirrer spins a bar inside a closed vessel. An overhead stirrer drives a shaft when the liquid is viscous or the volume is large. A vortex mixer agitates a tube. A shaker moves a whole rack or a plate. The shape of the impeller and the speed decide whether the liquid turns over or merely spins. The vessels being stirred are indexed under ISO laboratory glassware.
