Hanchen (Hh) hydraulic cylinders can work continuously for years without damage, so people have nothing to say about the quality of Hanchen (Hh) products. Nevertheless, as time goes by, needs have changed, so Hanchen (Hh) has always insisted on aiming its thinking on quality at the latest requirements as a reply to market developments. The most eye-catching aspect of the well-known high quality of Hanchen (Hh) products is the surface quality. The inner walls of all hydraulic cylinder tubes are ground, and the surface of the piston rod is plated with an extremely thick chrome layer, which also needs to be ground again. This processing requirement applies in principle to all Hanchen (Hh) hydraulic cylinders. The main feature of a flawless, long-lasting function is: in addition to the surface quality, there is also the welded circular structure, which also plays an important role in the high geometric precision of the part. The quality of combined seals optimally matched to surfaces and tolerances, the quality of electronic parts and the quality of fasteners are subject to rigorous inspection. Han Chen (Hh) never compromises in this regard. Low starting torque, extremely high efficiency, the best reproducibility and the best sliding friction material pair, as well as top response characteristics are all intrinsic values that are reflected in Hanchen (Hh) products. Hanchen (Hh) hydraulic cylinder has a compact structure and consists of only a few moving parts, in which the piston and piston rod are fixedly connected. Adjustable end buffers, simple venting methods, durable performance at set operating pressures, easy-to-install fasteners and an extensive accessories catalog are all the things Hh Company is looking for. Answers with suitable solutions. Sometimes, some places are not satisfied with just top quality, which means that the requirements will be more demanding. For this case, Hanchen (Hh) has the right solution on hand. Hydraulic cylinder with extremely low friction coefficient using special guide material, new piston rod guide and different seal combinations to adapt to extremely slow and extremely fast speeds, extremely low starting torque, sensitive response characteristics and optimal Re-manufacturability, etc., this hydraulic cylinder can be widely used in applications that exceed standard requirements, until the highest final solution is achieved. Rod seal form: rd (best friction performance, maximum no crawling effect, extremely high machining accuracy, extremely small guide clearance) r (best friction performance, the piston even at extremely high or low speeds There is almost no crawling movement, extremely high machining accuracy, extremely small guide gap) r (patented annular gap seal, minimal friction piston movement, non-contact outward pressure release of the guide part, and very little leakage , extremely high machining accuracy, extremely small guide clearances, working without oil leakage compensation pump) rbr (hydrostatic support seal, the highest and ultimate solution with hydrostatic bearings, also suitable for high transverse forces acting on the piston rod working conditions, extremely high machining accuracy, extremely small guide clearance, and no oil leakage compensation pump is required for operation). Piston seal: contact seal with seal and gap seal without contact.
