Description

In order to accelerate the transformation and innovation, we actively promote the research, development and application of new technologies and new series of the Semi Finished Products, Spherical Bearings, Guide Ring Seal. Our powerful demonstration effect has led and driven the development of many enterprises in the industry. We pay attention to the quality of life of our employees, respect them, make efforts to improve the working environment, improve the quality of life of our employees, and let them continuously share the fruits of high-quality corporate development.

In hydraulic cylinders the most commonly used guides are guide rings and guide strips. They accommodate radial loads of forces acting on the cylinder assembly and guide the rod in the cylinder head as well as the piston in the cylinder bore.

Our rod guide rings are made from round phenolic resin tubes, which is based on modified phenolic resin reinforced with ultra strong special fiber, added with solid lubricants, processed under certain temperature and pressure. Compare to other fiber-reinforced (cotton fiber, polyester fiber, polyamide fiber and so on) phenolic products, this material has the largest compressive strength, it is suitable used as back-up rings for mine, coal machinery and equipment.

work more smoothly against the cylinder bore and the sealing surfaces

high resistance to insufficient lubrication at low speeds

certain self-lubricating properties

significantly longer service life
