Product Parameter

Product Structure
Cylinder block, cylinder head, piston, piston rod and sealing device

1. Piston rod: Our high pressure lifting cylinders use a piston rod made using 40Cr steel sourced from LAIWU Steel Group (after heat treatment), with a metallographic structure reaching level 4 or higher in Chinese agricultural machinery industry standards. The surface hardness of the piston rod ranges between 50 HRC to 600 HRC as per customer requirements. The chrome plate surface also ensures a rust and corrosion resistance, proven by a 96 hour salt spray test.

2. Sealing ring: The sealing ring is imported from GUARNITEC, Italy and has undergone 50,000 fatigue tests with no leakages. The speed is 0.8m/s and the maximum pressure is 40MPa.

3. Cylinder block: The cylinder block is 20# steel from Baoji Steel that has undergone a rolling processing on the in-hole surface with the roughness reaching 0.2-0.4.

4. Cylinder head, piston: 45# steel, CNC processing.
