Buffer Bushing & Buffer Piston
Item | Material | Mechanical behavior |
Buffer Bushing | 45 | Surface High frequence quenching, hardness 52 to 60HRC hardening depth 1.0 to 2.0mm |
40Cr,42CrMo | Quenching, hardness 45 to 52HRC | |
HBsC4 | 220-270HB | |
Spheroidal graphite cast iron | ≥230HB | |
Buffer Piston | 15CrMo,20CrMo | Carburizing and quenching, hardness 56 to 62HRC |
Using feature | 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.Polishing out surface, fulfill the requirement of ABBOTT curve.Distinctive grinding process be used for machining of buffer bevel, to guarantee the requirement of the dimensions and angle.Rolling treatment be used for R grooves of buffer piston, roughness can be up to Ra0.4, tensile strength highly improve.Application to hydro-cylinder for digger. | |
