Rexroth CD350 Series Heavy-Duty Hydraulic Cylinder
Rexroth CD350 (also designated CG350) is an ultra-heavy-duty, single-rod/double-rod, double-acting hydraulic cylinder designed for 350 bar (35 MPa) high-pressure operation. It is the high-pressure variant of the CD250 series, built for extreme loads, shock conditions, and harsh industrial environments, conforming to ISO 3320 and German steel mill standards.

A: Depends on the style of tie-rod. We would like to cast and forge once the quantity above 100 pcs.
A: Well, it depends on the quantity and style of hydrualic cylinders, at least 60 days if we make casting and forging, at least 35 days by maching.
A: Sure, we are the manufacutuer and trading of hydraulic cylinder.
A: Double-Acting-have a port at each end, supplied with hydraulic fluid for both the retraction and extension. Single-Acting-hydraulic fluid enters through
a port at one end of the cylinder, which extends the rod by means of area difference. An external force or gravity returns the piston rod.
A: Sure. Show us the drawing, we will quote for you soonest.
A: Yes, we make and supply a wide rang of hydrualic cylinders as a proffetional manufacture, there are only some kinds of them show on the website. Freely contact us to get more information.
