3.Seal Kits
According to customers' requirements and work condition,we will choose suitable seal kits,including:Hallite,NOK,SKF,Parker,Merker,Trelleborg,China made,Taiwan made.We will supply you suitable seal kits to ensure hydraulic cylinders a long lifetime,easy maintenance and simple repairing.
4.Inspection and Testing
4.1 We have professional quality control department,every step from raw material to finished product is in the same factory,each procedure will be tested by professional inspector.
4.2 Before hydraulic cylinder is assemblied , every spare parts would be measured and cleaned .After hydraulic cylinder is assemblied , pressure test would be carried out one by one.We ensure the testing pressure is 30%-50% higher than rated pressure in almost one hour's test.Each hydraulic cylinder must be tested without any leakage.
Main material of this kind of pnematic cylinder:
Tube body: steel;
Piston rod:1045 hard chromed;
Cover: Q235:
Piston:45#;
Tie rod: high strength tie rod and screw nut;
