We can design and produce most kind hydraulic cylinder.Single
acting,double acting hydraulic cylinder.Big size and little size
hydraulic cylinder.3-6 stages Telescopic hydraulic cylinder.
(1) Construction Machinery cylinders for: loaders, excavator,
forklift, bulldozer, dumper, roller, crane ,pump truck,garbage
truck,garbage compactor and boat used hydraulic cylinder etc.
(2) Metallurgical Machinery cylinders for: decelerator, tile press
(3) Mining Machinery cylinders for: crasher, coal cutter shield
tunneling machine and dame gate etc.
(4) Agricultural & forestry machinery cylinders for: soil
preparation machine, harvester, weeder etc.
1. Raw materials entering the factory, 27SiMn, 40CrMo, ST52, 45#
steel tubes or bars for choice
2. Do the pre-treatment including pickling, phosphating and
saponification, and then cold-draw the seamless steel tubes.
3. Put the steel tubes into the tempering furnace to do the stress
relief annealing in convenience of the subsequent the processing.
4. Multi-roll straightening machine, with 10 straightening points,
achieves the automatic rolling straight improving the efficiency
5. Heat treatment to obtain work pieces with different properties
by changing their internal microstructure or surface chemical
6. Cylindrical degree can be controlled within 0.03mm and the
surface roughness is up to 0.4 by honing with range:φ40mm-φ450mm
and longest length: 12000mm
