What information do you need to quote a custom hydraulic cylinder?

Send bore diameter, rod diameter, stroke, retracted (pin-to-pin) length, working pressure, single- or double-acting design, mounting type at both ends, port size and thread standard, operating environment and estimated annual quantity. A drawing, a sample or a photo of the original nameplate shortens the quotation process.

Can you reproduce an OEM replacement cylinder from a sample?

Yes. Our engineers measure the sample, prepare a technical drawing and send it for your confirmation before machining starts, so interchangeability is agreed in writing before production.

Which standards do your parts and tooling follow?

We machine to the customer drawing in metric or imperial units. Typical references include ISO 6H thread tolerance for hydraulic cylinder nuts, DIN 69872 and JIS B6339 for CNC retention knobs, and ER collet systems for milling tool holders.

Do you supply hydraulic cylinder components separately?

Yes. We supply cylinder heads, pistons, nuts, flanges, bases, integrated barrels, bushings and spherical bearings, as well as hydraulic valve blocks, for cylinder builders and repair workshops.

How are export orders packed and shipped?

Goods are packed with standard export materials to prevent transit damage and shipped by sea, air or express courier according to your preference, with tracking information provided.

How quickly will I receive a reply?

Our sales engineers reply to email enquiries within 24 hours. You can also reach the team directly by phone or WhatsApp.
