Prince 8 INCH BORE WELDED CYLINDER Product Introduction
Overview
Prince 8‑inch bore welded hydraulic cylinders are heavy‑duty, double‑acting welded construction cylinders designed for industrial, agricultural, construction and material‑handling applications. Built with robust welded‑body structure without tie‑rods, they deliver high‑force performance under standard working conditions, featuring compact size, strong lateral‑load resistance and long service life.
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.
