Hydraulic Cylinder:

Made according to customers’ requirements:
Hydraulic cylinder is one of our main products, mainly used in Excavators, Rotary drilling rig, Tunneller and such engineering machines. Through long-time heat treatment production line processing introduced from Japan, it is of high strength, of high accuracy and durable, please call our company for details.

Our hydraulic cylinders are used for excavators and other construction machinery. They are of high working pressure, reliable performance, long life, easy installation, easy maintenance and so on. The seals are imported named NOK. The piston rod are made of high-quality alloy steel, after heat treatment, especially surface quenching, its hardness can reach HRC55, which can effectively prevent piston rod surface from bumps and strains. After the chrome-plating surface of piston rod being polished, the roughness of the surface is reduced and the service life of the seals is greatly extended.

 

The cylinder is made of alloy steel or medium carbon steel. After milling, pressing and such advanced processing technology, the roughness of the cylinder’s inside surface is reduced, the friction gets smaller, and the service life of the seals is extended. The two ends of hydraulic cylinder are equipped with buffer devices with good performance, which effectively relieves the inertial force generated by the end of travel, reduces the high speed and peak pressure to the least, lowers the noise and impact load, and makes excavator work steadily and coherently.

 

Our cylinder is used for Hitachi, Komatsu, Kobelco, Sumitomo, Daewoo, Hyundai, Carter, Volvo, Doosan, Kato,etc.

    Anhui Yiliya (YILIYA) Hydraulic Transmission Equipment Co. Ltd. is a

professional manufacturer of Planetary Gearbox, Hydraulic Cylinder, Crawler Chassis and Hydraulic Winch. As China Construction Machinery Industry Association designated supplier, we are given high attention by national leaders and supported continuously by the people within the industry. Shouldering the mission, we go through the development from made in China to created in China. Constant hard working, constant improving, constant pursuit is our constant style. Do what others can not do, advance despite difficulties, work with perseverance, and finally we did it! To rebuild the reputation of the fittings in construction machinery, Yiliya is capable to undertake the task. To revitalize Chinese industry, Yiliya is incumbent.

    In the early 1980s, Anhui Yiliya (YILIYA) was introduced Germany and Italian technology for research and production of Travel Drives, Swing Drives and Winch Drives on excavator. By now the company has had about 30 years’ history on manufacturing Planetary Gearboxes, Hydraulic Motor, Hydraulic Winch, Hydraulic Cylinder, Crawler Chassis, and therefore it accumulated plenty of manufacturing experience. It is an international and professional transmission equipment company whose products are manufactured according to international standard, through imitating and emulating by microcomputer and optimization by Finite Element Analysis. Our products are of high safety and superior transmission performance. Because of high quality and brand reputation, our products have been widely used in various Engineering Machinery(Rotary Drilling Rig, Crane, Pile Driver, Drilling), Mining Machinery(Tunneller, Coal Mining machine), Ship(Deck machinery), Metallurgic Equipment, High-speed Rail Equipment (Beam Carrier, Beam Lifting machine), Geological Exploration, Mining Machinery, Gardens, Military, Wind Power (Yaw and Pitch Drive, Wind Power Lifting equipment) and other areas, and middle-and-large tonnage Crawler Chassis have been listed as our company’s key products. Before 2006, our planetary gearboxes and hydraulic cylinders were mainly used for excavator. Now we apply the successful experience in the excavator to the research and production of components in different kinds of engineering machines and go into mass production of planetary gearbox (travel drive, swing drive, winch drive), heavy industry low-speed high-torque planetary gearbox, hydraulic winch, hydraulic cylinder, and crawler chassis. The main connection size of our products are of international standard. With the cumulative manufacturing experience, Yiliya improves products’ internal structure continuously. We constantly upgrade the design drawings so as to fully satisfy the customers’ requirements and pursue the excellence of transmission performance, which is bound to advance Yiliya Hydraulic Transmission Equipment Company to be in line with the international conventions. Superb technology, professional team, constant innovation, Yiliya is always working hard to provide effective service timely whenever the customers need. Our products can be a good substitute for Germany Rexroth, O & K, Italy Bonfiglioli, Brevini and America FAIRFIELD, RR, Japan Teijin and so on.

    We have nine workshops, including Blacksmithing, Rough Processing, Precise Processing, Heat Treatment, Dust-free Assembly, Checking, Testing and so on. In order to ensure the accuracy of each component and make quality consistent, from producing forgings, processing, heat treatment to testing, we produce our products strictly according to international standard. The company pays attention to every detail, from small product to whole management. We have various types of products and timely and thoughtful services which features international standard and Chinese price. Yiliya staff can tell confidently: Yiliya Hydraulic Transmission Co.,Ltd. is your best choice. You choose Yiliya, means you choose success. Our company has exported batches of products to Canada, Russia, America, Australia and some other areas of different countries.
