 Hänchen hydraulic components - Quality featuresPersuasive arguments by Hänchen:
Typical for Hänchen: the surface qualityOne of the most striking areas of the literal quality of Hänchen products is the surface: all cylinder barrels are honed (H7), the piston rods covered with a particularly thick chromium plating and then rehoned (f7). This applies in principle to all Hänchen hydraulic cylinders. "Inner values" of Hänchen productsNext to surface quality, the welded circular construction is also essential for trouble-free and durable operation. It is responsible for the outstanding geometrical accuracy of the component. The quality of sealing combinations, which are perfectly matched to surfaces and tolerances, of electronic components and of fastening parts is subject to stringent testing – here Hänchen knows no compromise. Low break-out torque, high efficiency, the finest reproducibility, ideal slider matching and a top response characteristic belong to the so-called "inner values", which Hänchen passes on to its products. Small but superiorHänchen hydraulic cylinders are compact and comprise only a few moving components, whereby the pistons are permanently fastened to the piston rods. Adjustable final stroke cushionings, simple venting capability, permanent operation at the specified working pressure, easy installation of fastening parts as well as a comprehensive range of accessories – the Hänchen way of responding to questions regarding suitable solutions. For high to maximum demands: leading the wayCertain cases need more than just top quality … they require that something more. Hänchen has just the right solution for such cases: extremely lowfriction hydraulic cylinders with some very special "guiding qualities". With new piston rod guides and various seal combinations: for extremely slow and extremely fast piston speeds, with a low break-out torque, sensitive response behaviour and good reproducibility … for the wide range of applications above and beyond standard needs, right through to high-end solutions. | | Outstanding geometrical precision of components
