Language
An Agricultural Machine Tractor Hydraulic Steering Cylinder is a double-acting hydraulic cylinder that converts hydraulic pressure from the tractor steering circuit into linear force on the steering linkage. When the operator turns the steering wheel, the steering valve directs oil to one side of the piston; the piston rod extends or retracts, pushing or pulling the steering arm, which turns the front wheels. When the wheel is released, the valve opens the return path and the cylinder comes back to neutral. The result is a steering effort that is nearly independent of the load on the front axle, which is exactly what a loaded tractor with a front loader or heavy implement needs.
The cylinder is a compact assembly, but every internal part — the bore finish, the piston seal, the rod seal and the wiper — matters for steering feel. A rough bore or a hardened seal produces stick-slip at low steering speed, which the operator feels as a notchy wheel. The Agricultural Machine Tractor Hydraulic Steering Cylinder uses high-precision CNC honing on the bore and double-lip seals on the piston and rod so that oil pressure converts into smooth linear motion without the jerks that make steering feel vague.

Five design characteristics separate the Agricultural Machine Tractor Hydraulic Steering Cylinder from a commodity hydraulic cylinder. The list below summarises what each one contributes on a working tractor.
CNC honing of the cylinder bore delivers a uniform internal surface, which is what makes the piston travel smooth and the steering response predictable. Surface finish is controlled to hold the piston seal contact stable across the full 130 mm stroke.
Body and rod are produced from high-strength alloy steel, and the piston and rod seals are wear-resistant double-lip compounds. The rod is chrome plated to resist pitting from dust, mud and field chemicals, extending seal life in service.
Multi-layer surface treatment on the cylinder body and mounting ends is specified against the actual environment that agricultural machines operate in — washdown, fertiliser splash, and long periods of outdoor storage between seasons.
The internal oil passages and the piston geometry are optimised so that pressure from the steering valve translates into cylinder motion without a lag. This is what makes the steering feel precise when the operator makes small corrections at speed.
The compact envelope and the standard mounting ends mean the cylinder drops into the steering linkage of common tractor platforms without modifying the steering arms or the hydraulic hoses. Port positions are confirmed at the time of order.
Every unit is produced under an ISO 9001 quality system with material verification, in-process dimensional checks and a final pressure and leak test before packing. Traceability documentation is available on request.
Port position, rod seal and dust wiper are visible in the close-up. Port positions are confirmed against the tractor hydraulic circuit at the time of order, so the steering hoses connect without modification.
The Agricultural Machine Tractor Hydraulic Steering Cylinder is specified wherever a tractor or agricultural machine requires a compact double-acting cylinder for steering or auxiliary hydraulic actuation. The applications below are the ones most often quoted on a Raydafon enquiry.
To confirm the correct Agricultural Machine Tractor Hydraulic Steering Cylinder and issue a quotation, Raydafon needs the five items below. For a straight replacement of an existing steering cylinder, the original cylinder part number or a dimensioned drawing is usually enough.
Send the five items below and Raydafon will confirm the bore, stroke, installation distance, mounting ends and lead time within one working day.
The Agricultural Machine Tractor Hydraulic Steering Cylinder is used for power steering on tractors and agricultural machinery. Hydraulic pressure from the tractor steering circuit drives the cylinder, which pushes or pulls the steering linkage and turns the front wheels. It is also used on self-propelled harvesters, municipal tractors and trailed equipment with hydraulic steering axles.
The standard configuration uses a 50 mm cylinder bore, a 25 mm chrome-plated piston rod, a 130 mm stroke and a 487 mm installation distance (pin-to-pin). Bore, stroke and installation distance can all be produced to a drawing when the tractor steering linkage requires a different configuration.
The cylinder body and rod are produced from high-strength alloy steel with a honed bore and a chrome-plated rod. Piston and rod seals are wear-resistant double-lip compounds, and the rod includes a dust wiper. The body and mounting ends receive a corrosion-resistant surface treatment for agricultural environments.
Yes. Send the original cylinder part number, nameplate photo or a dimensioned drawing and Raydafon will confirm whether the bore, stroke, installation distance, mounting ends and port positions match. Where the original is obsolete, a functionally equivalent cylinder can be produced against the same tractor steering geometry.
Pin, clevis and ball joint mounting ends are all available. Where the tractor uses a specific mounting end style, send a photo or a drawing and Raydafon will match the mounting geometry. Custom mounting ends and rod-end threads can also be produced.
Yes. Port positions are confirmed at the time of order against the tractor hydraulic circuit. Where the original cylinder has ports on a specific side or at a specific angle, send a photo or a dimensioned drawing and Raydafon will match the port layout so the hydraulic hoses connect without modification.
Yes. Raydafon produces a full range of hydraulic cylinders for agricultural machinery, including steering cylinders, loader cylinders, tipping cylinders for trailers, telescopic cylinders, and the hydraulic cylinder series covered under the Agricultural Machinery Hydraulic Cylinders category. Matching hydraulic drive gearboxes and PTO drive shafts are also available from the same factory.
Standard configurations ship in 15 to 30 days. Custom bore, stroke, mounting ends and port positions are confirmed with the quotation. As an OEM manufacturer, Raydafon can supply from single-unit replacement up to full production quantities. MOQ depends on the specific configuration and is confirmed when the specification is fixed.
Whether you are replacing a worn steering cylinder on an existing tractor, upgrading a steering circuit for a heavier front axle load, or sourcing agricultural steering cylinders in volume for a tractor OEM program, Raydafon can quote the Agricultural Machine Tractor Hydraulic Steering Cylinder to your bore, stroke, mounting end and port position requirements. OEM and project quantities supplied directly from the Ningbo factory.
