Description

At present, our production line has realized the improvement of the quality of our Rod Step Seals, Piston Wear Rings, Phenolic Resin Wear Rings and production efficiency, and obtained various advanced technical and economic indexes. We will be committed to providing customers with safe products and services to satisfy different users. Our company's talent training program covers a full range of culture, professional skills, and leadership abilities.

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
