Advanced design capabilities:

Guoyue's high-quality cylinder products are designed according to the standards of German first-line brand cylinders, with high product restoration and excellent substitutes for imported brands.

High-standard raw material requirements:

Guoyue's high-quality cylinder products are made of the same raw materials as German first-line brand cylinders. The cylinder barrel and piston rod are made of 45 steel, and the cylinder head guide sleeve is made of ductile iron QT400. All raw materials are subjected to corresponding heat treatment piston rod tempering treatment before processing, and the hardness reaches HB220-250, and the ductile iron material is annealed.

Fine processing technology:

The processing technology of the cylinder barrel adopts push boring honing to ensure that the surface finish of the inner hole reaches 0.2. The processing technology of the piston rod adopts turning, cylindrical grinding machine grinding, polishing and electroplating hard chrome, and the hardness reaches HV900-1100.

Detailed selection of spare parts:

The seals are selected from Japan NOK, Trelleborg and A+P, and the bolts are selected from EGM or TUZ, with a strength of 12.9.
