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.

China Hydraulic Cylinder Base MPM-HCBS11 Manufacturers, Manufacturer

Hydraulic Cylinder Base also known as cylinder base end, refers to the sealed bottom end of a hydraulic cylinder, primarily functioning to enclose the barrel, withstand fluid pressure, and provide mounting support. It is typically welded, bolted, or threaded to the barrel, with some designs incorporating fluid ports for oil flow. Depending on construction, it can be categorized as welded type, threaded/bolted type, or flange type, ensuring structural stability and pressure sealing. In double-acting cylinders, the base works in conjunction with the cylinder head to form a sealed chamber, enabling piston reciprocation.

Product Description

Description

A hydraulic cylinder base is a critical component of the hydraulic cylinder, located at the bottom of the barrel, primarily used to seal the barrel and withstand the pressure of the hydraulic system. Its core functions include sealing (preventing hydraulic oil leakage), pressure-bearing (maintaining system stability), and connection (integrating with components like the barrel and piston rod). Depending on the structure, hydraulic cylinder bases can be categorized into welded type (high strength, suitable for high pressure), threaded connection type (easy disassembly, ideal for medium-low pressure), and flanged connection type (excellent sealing, suitable for large-diameter cylinders). Common manufacturing materials include carbon steel, alloy steel, and stainless steel to meet different operational requirements.

Hydraulic cylinder bases are widely used in hydraulic systems for construction machinery, agricultural equipment, mining machinery, ships, and more. Their design and selection directly impact the sealing performance, pressure resistance, and service life of the hydraulic cylinder. The choice of connection method (welding, threading, or flanging) and material must be optimized based on working pressure, environmental conditions, and maintenance needs to ensure efficient and reliable operation of the hydraulic system.

Features

Hydraulic cylinder base is constructed from high-strength alloy steel with multi-stage sealing, delivering 35MPa+ pressure resistance and million-cycle seal life, ideal for high-pressure hydraulic systems in construction machinery, marine applications, and more.
