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.

Custom MPM Hydraulic Cylinder Piston MPM-HCPT11 Manufacturers, Factories

Hydraulic cylinder piston is the core component of the hydraulic cylinder. It is mostly made of metal, cylindrical, and precisely matched with the cylinder barrel. Its outer periphery is equipped with seals to prevent hydraulic oil leakage and is connected to the piston rod.

Product Description

Description

The outer diameter accuracy of the MPM brand hydraulic cylinder piston can reach ±0.01mm, the cylindrical error is controlled within 0.005mm, and the surface roughness Ra is as low as 0.2μm - 0.4μm, ensuring high-precision matching with the inner wall of the cylinder, effectively reducing leakage, reducing friction loss, and extending the service life of the piston and the entire hydraulic cylinder.

According to different working environments and media, high-quality sealing materials such as fluororubber and nitrile rubber are selected to ensure the compatibility and stability of the seals and hydraulic oil.

In order to enhance the hardness and wear resistance of the piston surface and improve the service life, the piston surface is subjected to special anti-corrosion treatment, such as chrome plating, nickel plating or chemical coating.

Features

When working, under the action of the hydraulic oil pressure difference, the piston moves linearly along the cylinder, converting hydraulic energy into mechanical energy to drive the external load. It is widely used in various hydraulic systems.
