Our products are used in a wide range of applications including mining and construction, agriculture and maintenance, load handling, forestry, lifting, recycling, defense, energy and more.
1. To efficiently absorb impact from hydro-cylinder with special designed floating buffer zone. It is a significant part for High-speed and High pressure buffer zone. 2. Polishing out surface, fulfill the requirement of ABBOTT curve. 3. Distinctive grinding process be used for machining of buffer bevel ,to guarantee the requirement of the dimensions and angle. 4. Rolling treatment be used for R grooves of buffer piston, roughness can be up to Ra0.4, tensile strength highly improved. 5. Application to hydro-cylinder for digger.
