    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.

    Q: What’s the MOQ of customized tie-rod cylinder?

    A: Depends on the style of tie-rod. We would like to cast and forge once the quantity above 100 pcs.

    Q:What’s the lead time of customized tie-rod cylinder?

    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.

    Q: Are you the manufacturer of hydrualic cylinder?

    A: Sure, we are the manufacutuer and trading of hydraulic cylinder.

    Q: What is the difference between double acting and single acting cylinders?own controlled by the pump or the valve or is it only one speed?

    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.

    Q: I have a drawing, could you customized cylinder as my drawing?

    A: Sure. Show us the drawing, we will quote for you soonest.

    Q: Could you make the cylinder which is not on the above data sheet?

    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.
