Description
Plastic double universal joint, Ø 14 mm, for glass shafts is a compact connecting element designed to compensate for angular or axial misalignment between a stirrer drive and the stirring shaft in laboratory and process setups. With an outer diameter of 14 mm and a maximum torque rating of 1,3 Nm, it provides a reliable flexible link that protects glass shafts from excessive stress while maintaining smooth power transmission. The component is intended specifically for use with glass stirring shafts, making it suitable for glassware-based mixing applications where alignment tolerances must be accommodated without rigid coupling. Supplied as a single piece with a net weight of 0,175 kg, this double Cardan-style joint (Rettberg) offers a practical solution for stirrer couplings and quick-connect arrangements in research and production environments. Its plastic construction supports gentle engagement with fragile glassware while the double universal joint geometry absorbs offset in both angle and axis. Ideal for laboratory stirring systems that require dependable misalignment compensation between drive and shaft.

Questions about Stirrer coupling clamp, Ø 14 mm, double universal joint, plastic,
What is this article?
Stirrer coupling clamp, Ø 14 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 Lab instruments.
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.
