Factory Direct Forklift Hydraulic Cylinder Solutions Engineered for Heavy Duty Performance and Leak Free Operation

Forklift Hydraulic Cylinder Supply for Tilt, Lift and Side-Shift Mechanisms

Different forklift functions put different demands on the cylinder. The tilt cylinder, the lift cylinder and the side-shift cylinder are not interchangeable — each needs its own bore, stroke, rod ratio and mounting geometry to suit the mast and carriage it operates.

Key components are made from high-strength alloy steel, with the rod surface electroplated or hard-chrome treated for corrosion and wear resistance. The result is smooth movement, fast response and stable sealing under frequent daily operation, not just during the first week after installation.

How to Rebuild a Forklift Hydraulic Cylinder

Rebuilding a forklift hydraulic cylinder is not simply a matter of unscrewing the end cap and replacing the rubber ring. The process has five stages and each one matters — skip a step and the unit will leak again within days of going back into service.

1. Depressurise and remove the cylinder Release system pressure, disconnect the hydraulic lines and remove the cylinder from the truck. Loosen the end cover bolts with a wrench and pull the piston rod assembly out slowly, taking care not to scratch the cylinder bore. If there is a lot of oil inside, drain and clean before continuing.
2. Inspect every removed component Check the piston, rod and seal rings one by one for deformation, wear, edge loss or rust. A single wear mark can be the source of the leak, so do not skip the close inspection.
3. Replace all aged or damaged seals Confirm specification before fitting. Some cylinders use combined seals, and installing them in the wrong orientation will cause immediate failure regardless of how well the rest of the rebuild is done.
4. Reassemble in the original order Install the piston rod gently and keep the centre axis aligned throughout. If the rod is not properly centred, even a correctly rebuilt cylinder will leak within a few days of operation.
5. Pressure test before refitting Mount the assembled cylinder on pressure test equipment and check for internal leakage or jamming. Only after the test passes should it be installed back on the forklift.

How to Remove a Hydraulic Cylinder from a Forklift

Removal sequence and handling details determine whether the job takes twenty minutes or damages surrounding components. The four stages below are the standard procedure our service partners follow.

After the cylinder is off the truck, seal the oil port straight away. Raydafon supplies hydraulic cylinder products and seal kits matched to a wide range of forklift models, so users can restore equipment operation quickly rather than waiting on custom parts.

Who We Supply

About Raydafon

Raydafon is a manufacturer focused on hydraulic and transmission system solutions. We do not rely on promotional language — we build products steadily and let reliable quality carry the business. Over the years we have concentrated on the development and production of hydraulic cylinders, with a broad model range and flexible adaptation for construction machinery and special vehicle applications.

Beyond forklift hydraulic cylinders, our product range covers mobile crane hydraulic cylinders, garbage truck hydraulic cylinders and aerial work vehicle hydraulic cylinders, all using high-strength materials and precision processing to operate stably under high-pressure, high-frequency working conditions.

Alongside hydraulic cylinders, Raydafon supplies a complete power transmission product line including PTO shafts, agricultural gearboxes, precision gears and planetary gearboxes. Whole-machine manufacturers, repairers and parts dealers can source multiple components from one supplier, eliminating duplicate coordination work.
