Q: How many hours the ROD NSS testing?

A: NSS testing, our hydraulic rod can endure 200hours, 300 hours ,500hours,1000hours, Base on your request.

Q: Hydraulic cylinder thrust calculation

A: Hydraulic cylinder inner diameter = piston diameter = 200MM piston area = π (200 / 2) square = 3140 square mm = 31.4 square centimeter 25MPA = 250KG / square centimeter maximum thrust = pressure * piston area = 250 * 31.4 = 7850KG = 78500 Newton This is the maximum thrust.

Q: What is the advantage of the material used for the dump truck cylinders compared with the cold drawn tube ST52/E355/E460?

A: Our dump truck hydraulic cylinders are made of tempered 27simn material.

Tensile strength and yield are both greater than 950MPA;

Cold drawn tube ST52/E355/E349, tensile strength and yield 600--700MPA, CMG hydraulic cylinder maximum working pressure is 220Bar, using ST52/E355/E460 material, the maximum working pressure is 190Bar.
