Descrizione
The grain tank lifting cylinder is a precision hydraulic component built specifically for the demanding environment of combine harvester grain tank management. When a combine operator needs to tilt the grain tank for maintenance access, inspection, or full cleaning between harvests, this cylinder delivers the controlled, repeatable force that keeps downtime to an absolute minimum. Across the British agricultural landscape — from the barley fields of East Anglia to the wheat belts of Yorkshire — reliability during harvest season is non-negotiable, and a single hydraulic failure can cost a contracting business thousands of pounds in lost output per day.
With 18-plus years of specialised hydraulic cylinder application engineering behind every unit we manufacture, this grain tank lifting cylinder is produced to meet the rigorous duty cycles of modern high-capacity combines. The double-acting design gives operators positive control in both the extend and retract directions, unlike single-acting alternatives that rely purely on gravity or spring return. That matters enormously when the tank is loaded with residual grain or the machine is parked on uneven ground — both common realities in British field conditions.
Why This Cylinder Outperforms Generic Alternatives
Validated across UK agricultural OEM supply chains and independent machinery dealers.
Double-Acting Precision Control
Hydraulic pressure drives both extension and retraction, giving operators confident, smooth tank movement in any field orientation — critical when combines park on sloping ground or carry residual grain loads.
High Pressure Rating — 16.7 MPa Working
A working pressure of 16.7 MPa and maximum withstand pressure of 24.5 MPa means the grain tank lifting cylinder handles surge loads without seal failure — the kind of load spikes that destroy cheap imports mid-harvest.
65mm Bore — Optimised Force-to-Weight Ratio
The 65mm bore diameter is carefully calculated to generate ample lifting force for full grain tank loads while keeping the 18 kg unit weight low enough for straightforward field replacement by a two-person maintenance crew.
Robust Sealing for Dusty Harvest Conditions
Grain dust, chaff, and fine silica particles are the enemy of any hydraulic cylinder seal system. The wiper seals and rod surface finish on this unit are specifically chosen to exclude contamination during open-air combine harvester operation.
Direct OEM-Compatible Mounting Dimensions
Installation distance of 823mm aligns with the mounting points found on leading combine harvester platforms, allowing quick like-for-like replacement without any fabrication work or bracket modification in the field.
Corrosion-Resistant Surface Treatment
Stored outdoors or in partially open farm buildings through wet British winters, agricultural cylinders face punishing humidity and temperature cycles. Chrome-plated rod surfaces and treated end caps resist rust formation during extended off-season storage periods.

How It Works, What It’s Made Of & Where It’s Used
▶ Working Principle
This grain tank lifting cylinder operates on the standard double-acting hydraulic principle. Pressurised hydraulic oil is directed alternately to the cap-end port and the rod-end port via the combine harvester’s hydraulic control valve. When oil enters the cap-end, the rod extends, pushing the grain tank upward. When the operator reverses the valve, oil fills the rod-end chamber and the rod retracts positively under pressure, lowering the tank in a controlled manner. The 607mm stroke provides exactly the travel needed to clear all internal access panels. A cushioning arrangement at both end-of-stroke positions absorbs impact energy and protects the mounting brackets from shock loads that accumulate rapidly over thousands of actuation cycles across a long harvest season.
▶ Materials
The cylinder barrel is cold-drawn seamless steel tube, honed to an internal surface roughness that maximises seal life while minimising stick-slip at low speeds. The piston rod is high-strength carbon steel, hard chrome plated to a minimum depth that withstands abrasive crop dust without micro-pitting. All seals are polyurethane-based compounds selected for compatibility with standard ISO 46 and ISO 68 hydraulic oils commonly used in UK farm machinery. End caps are precision-machined from ductile iron, providing the thread engagement strength necessary for the 24.5 MPa withstand pressure rating. External surfaces receive an epoxy primer followed by a polyurethane topcoat for long-term outdoor corrosion resistance.
▶ Application Scenarios
The grain tank lifting cylinder is the correct replacement unit for combine harvesters operating in wheat, barley, oilseed rape, and maize harvesting operations across England, Scotland, and Wales. It suits both large estate farm fleets and agricultural contracting businesses managing multiple machines. Dealers and machinery service centres in Lincolnshire, Norfolk, Suffolk, Yorkshire, and Aberdeenshire will find this unit particularly relevant given the cereal crop density in those regions. The cylinder also fits certain self-propelled forage harvesters where an identically dimensioned tipping hydraulic cylinder is specified, making it a dual-application stocking item for workshops servicing mixed machinery fleets.

Zero Downtime Across 3,400 Harvested Acres — A Cylinder Replacement Success
Lincolnshire Grain Contracting Ltd operates a fleet of four large combine harvesters serving arable farms across the Fens. During the 2023 harvest, they experienced a mid-season grain tank cylinder failure on their flagship machine, resulting in 11 hours of unplanned downtime during peak wheat harvest — a loss estimated at over £6,200 in missed contractor revenue. For the 2024 season, they sourced four HCYY11112016 grain tank lifting cylinders as pre-season replacement units across their entire fleet. Workshop manager David Hartley reported that all four cylinders were installed in under two hours per machine, with no bracket modification required. Across 3,400 harvested acres through a demanding season that included several days of rain-interrupted cutting and intensive grain tank cycling, not a single cylinder-related stoppage was recorded. Post-season inspection showed negligible rod wear and zero seal weeping.
“We fitted this grain tank cylinder to our Class Lexion at the start of drilling prep last autumn. Perfect fitment, no leaks after 600 hours, and the price from this supplier was significantly better than the OEM dealer quote. Will be ordering again.”
— Farm Manager, East Yorkshire, UK
“We stock these as standard workshop items now. Three units sold this season to local combines and every customer has come back happy. Dimensions match what comes off the machine, seals hold properly, and delivery was fast. Exactly what a farm parts supplier needs.”
— Cambridgeshire, UK
“Our wheat operation in Western Australia runs three Deere combines and we’ve been sourcing grain tank cylinders from this supplier for two seasons. Pressure ratings are accurate, the units handle our long daily hours without issue, and the technical team answered our specification questions promptly.”

Manufacturing Facility & Custom Engineering Capability
Our hydraulic cylinder manufacturing facility operates CNC honing machines, precision turning centres, and automated seal assembly lines under an ISO 9001-certified quality management system. Every grain tank lifting cylinder leaving the facility is pressure-tested to 1.5 times its rated working pressure before dispatch — meaning each HCYY11112016 unit is verified to 25 MPa on a calibrated test bench before it reaches your workshop or farm.
Custom engineering is a genuine core competency at this facility, not an afterthought. If your combine harvester platform requires a bore diameter other than 65mm, a stroke length that differs from the standard 607mm, alternative port thread standards, modified clevis or trunnion mounting configurations, or a different paint specification for corrosive coastal environments, our engineering team can produce an adapted unit. Minimum order quantities for custom configurations are kept deliberately low to make bespoke solutions accessible to independent machinery dealers and small fleet operators as well as large OEM accounts.
UK-based agricultural machinery importers, combine harvester dealers, and farm parts wholesalers are encouraged to enquire about annual supply agreements, which can include reserved stock allocation held ahead of the pre-harvest ordering surge that typically occurs between April and June each year.

Frequently Asked Questions
Voice-search friendly answers for UK agricultural buyers, dealers, and machinery engineers.
What is the correct grain tank lifting cylinder for a combine harvester with a 65mm bore requirement in the UK?
The model HCYY11112016 is the purpose-built unit for this specification. With bore dimensions of 65mm (bore) by 35mm (rod) and a 607mm stroke, it matches the mounting and performance requirements found on several leading combine platforms sold in the UK market. The installation distance of 823mm ensures a direct drop-in replacement without any bracket modification.
How much does a replacement grain tank hydraulic cylinder cost and where can I get a price quote for UK delivery?
Pricing depends on order quantity, any custom specification requirements, and current shipping rates to your UK location. To receive an accurate quotation including delivery to England, Scotland, or Wales, email [email protected] with your machine make and model, the bore and stroke requirement, and your approximate annual volume. Our team typically responds with a full price breakdown within one business day.
Which hydraulic oil is compatible with this grain tank cylinder for use in British combine harvesters?
The seals in this cylinder are formulated for compatibility with standard mineral-based hydraulic oils to ISO 46 and ISO 68 viscosity grades — the most widely used combine hydraulic fluids across UK farming operations. Most combine harvesters from CLAAS, John Deere, New Holland, and AGCO specify oils within this viscosity range. If your machine uses a synthetic or bio-degradable hydraulic fluid, contact us to confirm compatibility before ordering.
How do I know when a grain tank lifting cylinder needs replacing rather than just having its seals serviced?
A cylinder that drifts (slowly retracts under load without any valve input), shows visible oil weeping at the rod seal, produces a jerky or uneven lifting motion, or fails to hold the tank in position after the control valve is released is showing classic end-of-service indicators. If the piston rod surface shows scoring, pitting from grain dust, or corrosion blistering beneath the chrome plating, seal replacement alone will not restore reliable function — a new cylinder is the correct intervention. Given how critical grain tank access is during harvest, proactive replacement at the start of each season is a practice many larger contracting operations now follow.
Can I get a grain tank cylinder supplier in the UK who offers custom stroke lengths for non-standard combine harvester platforms?
Yes. Our manufacturing facility produces custom-stroke grain tank lifting cylinders against a customer’s specified dimensions.
