Used Hydraulic Cylinders for Construction Equipment

What are the 3 main types of hydraulic cylinders?

• Single-acting cylinder: pressurized in one direction only, it returns by gravity or spring, as found in some axle locking systems
• Double-acting cylinder: pressurized in both directions, it controls extension and retraction; the most common type on construction equipment, from dumping to steering
• Telescopic cylinder: multiple nested tubes extend sequentially to provide a long stroke in a compact size, typical for tipping buckets

How a hydraulic cylinder works: piston, rod, and supply

A hydraulic cylinder converts pressurized oil energy into mechanical energy as linear motion. Oil enters through an inlet and pushes the cylinder piston, connected to the rod that extends from the body. In a double-acting cylinder, a second supply returns the piston; in a single-acting cylinder, the return is by load or spring. Seals on the piston and head ensure tightness; these are the parts that wear out first.

Used single-acting or double-acting hydraulic cylinders

The choice depends on the original application on your equipment. A double-acting cylinder cannot replace a single-acting one without hydraulic circuit modification, and vice versa. Note the manufacturer's reference of the original part, rod diameter, bore, stroke length, and mounting type before ordering, as these dimensions determine compatibility.

Hydraulic cylinders for construction equipment and excavators: buckets, trailers, mini-excavators

• Bucket cylinder: often double-acting, used on articulated and rigid dump trucks, designed for intensive dumping cycles
• Lift arm cylinder and stabilizer cylinder for backhoe loaders and loaders
• Boom cylinder, stick cylinder, and offset cylinder for excavators and mini-excavators
• Bucket tilt cylinder and bucket curl cylinder controlling bucket attack angle and loading
• Steering cylinder for maneuverability in articulated machines

Telescopic hydraulic cylinders: long stroke and heavy-duty

On dump truck beds and tip trailers, telescopic hydraulic cylinders provide extended stroke in a compact package. Heavy-duty cylinders for excavators and large loaders require precise bore, rod, and mount checks before any replacement.

Hydraulic cylinders for Kubota mini-excavators and other brands

For mini-excavators from Kubota, Yanmar, or Takeuchi, boom, stick, bucket, and offset cylinders are specific to each model. Provide the reference engraved on the cylinder body or the machine's serial number: our advisors will find the compatible cylinder.

Used hydraulic cylinders for individuals or professionals

Codimatra sells used hydraulic cylinders to construction companies, rental businesses, and private owners maintaining their equipment. The process is the same: identify the machine, cylinder position, and dimensions, then have our advisors confirm compatibility before ordering. A genuine used cylinder installs without adaptation on the intended machine, facilitating maintenance.

How to tell if a hydraulic cylinder is faulty?

• Visible oil leaks around the rod or seals
• Slow or incomplete movement, indicating internal seal failure
• Scratched or corroded rod surfaces
• Jerky movement or abnormal noise during extension
• Load descends on its own when stopped

Prices and catalog of used hydraulic cylinders

Price depends on rod diameter, stroke, operating pressure, cylinder type, and original machine. A mini-excavator cylinder is considerably less expensive than a heavy-duty dump truck bucket cylinder. The listed price is shown on each part's sheet or provided by quote at 05 53 96 16 43 using the manufacturer's reference.
