KICAN manufactures replacement hydraulic cylinders for equipment maintenance, aftermarket distribution, and discontinued OEM cylinder replacement. We can develop a compatible cylinder from an OEM part number, technical drawing, existing cylinder sample, equipment model, or a complete set of installation dimensions.

Our replacement hydraulic cylinders are used in excavators, bulldozers, loaders, agricultural machinery, lifting equipment, industrial presses, material-handling systems, and other hydraulic equipment. Bore diameter, rod diameter, stroke, mounting structure, oil ports, seals, materials, and surface treatments can be adjusted to match the original installation and operating conditions.

When Do You Need a Replacement Hydraulic Cylinder?

A replacement cylinder is often required when the original component is damaged, discontinued, unavailable locally, or subject to a long OEM delivery time. It can also provide a practical alternative when repeated repairs no longer deliver reliable performance.

Typical replacement requirements include:

• Leaking, bent, corroded, or heavily worn cylinders

• Discontinued OEM hydraulic cylinder models

• Long delivery times for original replacement parts

• High-cost OEM cylinders for older equipment

• Cylinders with damaged barrels, rods, pistons, or mounting ends

• Modified equipment requiring different mounting or port positions

• Imported machinery with limited local spare-parts support

• Fleet maintenance requiring repeat supply of the same replacement model

The replacement cylinder must be matched by function and dimensions rather than appearance alone. Mounting centers, stroke, closed length, bore, rod diameter, port position, working pressure, and load conditions must all be confirmed before production.

Replacement Cylinder Types

Double-Acting Replacement Hydraulic Cylinders

Double-acting cylinders use hydraulic pressure for both extension and retraction. They are commonly used in construction machinery, agricultural equipment, material handling systems, presses, lifting platforms, and industrial automation.

KICAN can customize double-acting cylinders according to the required bore, rod, stroke, pressure rating, mounting style, port direction, and seal configuration.

Single-Acting Replacement Hydraulic Cylinders

Single-acting cylinders use hydraulic pressure in one direction and return through gravity, a spring, or the applied load. They are commonly used in lifting, clamping, tipping, gate control, jacks, outriggers, and auxiliary mechanisms.

Return method, spring force, installation position, load direction, and available mounting space must be confirmed during replacement matching.

Excavator Replacement Hydraulic Cylinders

We supply replacement boom, stick, and bucket cylinders for excavators. Matching can be completed using the excavator brand and model, OEM part number, old cylinder, drawing, or installation measurements.

Important information includes pin diameter, mounting width, retracted length, stroke, port position, working pressure, and the function of the cylinder.

Hydraulic Cylinder Manufacturing Range

Our standard and custom production capabilities cover a broad range of mobile and industrial applications.

Standard working pressures generally range from 10 to 31.5 MPa, while customized designs can be engineered for pressures up to 70 MPa, subject to technical review.

Standard bore diameters range from approximately 20 to 400 mm. Larger custom cylinders with bore diameters up to 1,000 mm can be evaluated according to the structure, pressure, stroke, material, and equipment requirements.

Available stroke lengths generally range from 100 to 5,000 mm. The practical stroke limit depends on the cylinder type, rod stability, mounting arrangement, operating speed, and available installation space.

Available configurations include:

• Single-acting cylinders

• Double-acting cylinders

• Piston cylinders

• Plunger cylinders

• Telescopic cylinders

• Welded hydraulic cylinders

• Tie-rod cylinders

• Servo hydraulic cylinders

• Spring-return and gravity-return cylinders

Final production specifications are confirmed after reviewing the application, drawings, operating pressure, load, duty cycle, and environmental conditions.

How We Match an Existing Hydraulic Cylinder

1. Submit Available Cylinder Information

You can send any combination of:

• OEM part number

• Equipment manufacturer and model

• Existing cylinder drawing

• Photos of the old cylinder

• Physical cylinder sample

• Bore and rod diameters

• Stroke length

• Retracted and extended lengths

• Mounting dimensions

• Pin diameters

• Port thread and position

• Working pressure

• Required quantity

A complete drawing is helpful but not always required. Clear photographs and accurate measurements can be used for an initial technical assessment.

2. Confirm Critical Installation Dimensions

Our technical team checks whether the new cylinder will match the existing equipment. Critical dimensions include:

• Pin-to-pin closed length

• Maximum extended length

• Effective stroke

• Mounting-end type

• Pin diameter and mounting width

• Clevis, flange, trunnion, or foot dimensions

• Hydraulic port type, size, and orientation

• Available installation clearance

The replacement cylinder should not be approved solely by comparing bore and stroke.

3. Review Operating Conditions

We confirm:

• Maximum working pressure

• Peak load

• Extension and retraction speed

• Operating frequency

• Side-load risk

• Ambient and oil temperature

• Dust, moisture, salt, or corrosive exposure

• Required seal material

• Rod coating requirements

This review helps determine suitable tube material, rod diameter, seals, bearings, welding structure, and surface protection.

4. Drawing Approval and Quotation

After the dimensions and operating requirements have been confirmed, we prepare a technical proposal and quotation. Production begins after the customer approves the drawing and specifications.

5. Prototype and Batch Supply

A prototype can be produced for installation and performance verification before repeat orders. After approval, the same design can be supplied for equipment fleets, repair networks, distributors, or aftermarket spare-parts programs.

Custom Options for Replacement Projects

Replacement hydraulic cylinders can be customized by:

• Bore and rod diameter

• Stroke length

• Closed and extended length

• Working and test pressure

• Mounting structure

• Pin and bushing dimensions

• Hydraulic port size and position

• Seal material

• Barrel and piston material

• Rod coating

• Corrosion protection

• Integrated valves

• Position sensors

• Cushioning structure

• Paint color and surface finish

• Customer branding and packaging

We can also modify the original design where the existing cylinder has recurring leakage, insufficient rod strength, poor sealing, corrosion, or an unsuitable mounting structure. Any design change must be approved before production.

Inspection and Performance Verification

Replacement cylinders require consistent dimensions and reliable sealing because even a small installation mismatch can prevent assembly or cause premature failure.

Inspection and verification can include:

• Raw-material inspection

• Bore and rod dimensional checks

• Mounting dimension inspection

• Weld inspection

• Seal and assembly inspection

• Pressure holding tests

• Internal and external leakage checks

• Stroke and movement verification

• Surface-treatment inspection

• Final drawing comparison

Additional testing requirements can be discussed for OEM, fleet, and batch-supply projects.

MOQ, Samples, and Lead Time

Prototype and small-batch orders are available for replacement hydraulic cylinder projects. The MOQ is confirmed according to the cylinder type, dimensions, material, tooling requirements, and required quantity.

Custom samples can be produced for dimensional, installation, and performance verification. Sample costs and freight are confirmed after the available drawings, measurements, and technical requirements have been reviewed. Eligible sample costs can be credited toward a subsequent batch order.

For urgent replacement projects with complete and confirmed specifications, prototype production can be completed in as little as 8–10 working days, depending on design complexity, material availability, seals, machining, and testing requirements. The final batch-production lead time is confirmed after drawing approval and quantity review.

Frequently Asked Questions

Can you replace a discontinued OEM hydraulic cylinder?

Yes. A replacement can be evaluated from the OEM part number, equipment model, old cylinder, technical drawing, or complete installation measurements. Production feasibility depends on whether the critical specifications can be confirmed.

Can you manufacture a cylinder from an old sample?

Yes. An old cylinder can be used for dimensional inspection and reverse engineering. Its wear or deformation must be considered before the final drawing is approved.

Is the replacement cylinder identical to the OEM product?

The cylinder can be designed as a compatible replacement for the required installation, stroke, pressure, and operating function. It should not be described as an original OEM component unless it is supplied under an authorized arrangement.

Can the original design be improved?

Yes. Subject to technical review, the rod size, seals, materials, surface treatment, mounting structure, or port configuration can be adjusted to improve durability or suit changed operating conditions.

Do you accept one-piece or prototype orders?

Prototype and small-batch projects are accepted. MOQ depends on the cylinder size, material, tooling, machining complexity, and commercial value of the order.

How do I confirm whether a replacement will fit?

The safest method is to compare the drawing and all critical installation dimensions, including retracted length, stroke, mounting width, pin diameter, port position, and available clearance.
