Hydraulic Cylinder / Ram — 2.5" Bore — Australian Made

Certified Australian Made, assembled at Tuff Manufacturing's Queensland factory from materials sourced exclusively within Australia. Backed by a 2-year warranty and individually oil tested before dispatch.

All-steel double-acting cylinder, 2.5" bore, 1.5" hard chrome rod, female clevis with 1" high tensile steel pin and spring steel R-clip retainers at both ends.

Producing up to 6.6 tonnes push force extending and 4.3 tonnes pull force retracting at 3,000 PSI (207 bar) — actual force depends on stroke length (see chart below).

This cylinder can also be used as a single-acting ram (e.g. gravity pull or push down). Dual 3/4" UNO ports at each end give more options for connecting in tight spots.

Australian Tax Invoice and 2-year warranty included on every order.

WARNING: Hydraulic cylinders without a hose burst valve, pilot-operated check valve, or counterbalance valve mounted directly to the cylinder do not meet Australian Standard AS1418.8, nor occupational health & safety rules.

Why "high quality" actually means something here

Every wear component in this cylinder carries a named material spec and a tested performance figure — here's the breakdown.

Rod — hard chrome plated, high tensile steel

• Precision turned and polished, then electrolytically hard-chrome plated for surface hardness and corrosion resistance

Barrel, gland nut, clevis — steel

• Same base materials and manufacturing process as our imported range: cold-drawn seamless honed steel barrel, taken through cutting, acid pickling, phosphating, cold drawing, annealing, straightening, honing/skiving, and roller burnishing
• Rod end clevises are precision drilled and tapped on a Mazak CNC quick-turning center, loaded and unloaded by robotic handling — this is the "robotic manufacturing" behind our Australian Made claim, not just a marketing line

Pins — 1" high tensile steel with spring steel R-clip retainers

Piston — steel, with dual guide rings

• Dual guide rings keep the piston seal square through the full stroke, which is what extends seal life on this design compared to a single-ring piston

Piston seal — Hallite 780, five-part assembly

• Max pressure 400 bar, -30°C to +100°C, piston linear speed up to 0.5 m/sec
• Comprised of a nitrile rubber sealing element, two split support rings, and two split L-shaped guide rings positioned either side of the seal
• Nitrile sealing element uses a multi-lip profile for dynamic sealing with minimal low-pressure friction; under pressure, the extending lips of the support rings protect it from extrusion damage
• Support/guide rings are a synthetic fibre-reinforced polyester composite with synthetic graphite micro-powder — low friction coefficient, high load-carrying capacity, low water absorption, chemical resistance, UV-stable for outdoor service

Rod wiper seal — Hallite 834

• Rated -45°C to +110°C, rod Linear speeds up to 4 m/sec
• Moulded in Hythane® 181 polyurethane for wear resistance
• Internal moulded ribs resist wiper blow-out from pressure trapped between the wiper and main rod seal

Gland nut (rod) seal — Hallite, Hythane® 181

• Rated 400 bar max pressure, -45°C to +110°C, Rod Linear speeds up to 1 m/sec

Built for repeat daily use

Each cylinder is individually oil tested at the factory before dispatch and backed by a 2-year warranty — the same material and seal specs above are what stand behind day-to-day use in earthmoving, transport, and farm equipment.

We can supply cylinders in many bore, stroke, and port orientations — send us a question for different sizes and costings.

Many adaptor threads, hydraulic hose, and field-fit hose fittings also available — see our other listings.

Re-seal kits also available.

Suited to hydraulic applications across industry, manufacturing, transport, and farming — including tilt tray and skip bin trucks, front end loaders, backhoes, tractors, farm implements, and log splitters.

Comes complete with a female clevis at each end.
