Hydraulic Rams & Tools

Hydraulic Rams & Puller Sets

AIMS Industrial stocks a focused range of hydraulic rams and ram-based puller accessories from Trax, built around two ram platforms — the 8 tonne ARX-7000 and the 10 tonne ARX-8000. Each ram is supported by a set of purpose-made accessories (extensions, adaptors, a centre locator, a twin head and a threaded ram ring), plus a complete 2 & 3-leg hydraulic puller set for bearing, gear and pulley removal. If you're pressing a bush, pulling a bearing off a shaft, or need a compact, high-force tool for a workshop or field maintenance job, this is the range to start with.

Quick Reference — Hydraulic Ram Range

Exact stroke length, collapsed height and pump/hose inclusions vary by item — check the individual product listing or contact our team to confirm before you order, especially for confined-space or tight-clearance jobs.

What a hydraulic ram and puller system actually is

A hydraulic ram is a piston-and-cylinder actuator that converts hydraulic fluid pressure into a large, controlled linear force in a compact package — far more force than can be applied by hand tools alone. On its own, a ram presses or pushes in a straight line. Paired with a mechanical puller frame — a 2-leg or 3-leg yoke that grips a bearing, pulley or gear — the same ram becomes a hydraulic puller, drawing the component off a shaft instead of pushing it. That's the logic behind the AIMS Trax range: a ram body plus a set of accessories that adapt it to whichever job is in front of you.

The two most common ram actuation types in the market are single-acting (the ram extends under hydraulic pressure and retracts under spring or gravity force once pressure is released) and double-acting (hydraulic pressure drives the ram in both directions, giving a powered, controlled retraction). For the specific actuation type, stroke and collapsed height of the Trax ARX-7000 and ARX-8000 rams, check the product listing or ask our team — we'd rather confirm the exact spec against your job than have you guess from a title.

The ram bodies — ARX-7000 (8T) and ARX-8000 (10T)

The ARX-7000 and ARX-8000 are the two ram bodies in the range, rated at 8 tonne and 10 tonne respectively. They form the base of two separate accessory platforms — the "70-series" (currently the ARX-7088 hydraulic-to-mechanical adaptor) and the "80-series" (extensions, centre locator, twin head, threaded ring and the 2 & 3-leg puller set). Choose the ram body first, then build out the accessory set that matches the job.

Ram accessories — extensions, adaptors and fittings

The accessory line extends what a single ram body can do without buying a second tool. The ARX-8015 ram extension and the ARX-8014 2" extension increase the ram's reach for jobs where the standard collapsed height won't get you to the work. The ARX-8013 centre locator keeps the ram square and on-axis over a shaft or bolt so force is applied straight rather than at an angle — important both for a clean result and for operator safety. The ARX-8011 threaded ram ring gives a threaded fixing point for mounting accessories to the ram face, and the ARX-8012 twin head (to suit YC101) provides a dual-contact head for jobs where a single point of contact isn't suitable. The ARX-7088 hydraulic-to-mechanical adaptor lets the 8T ram body drive a compatible mechanical puller frame hydraulically rather than by hand-cranked screw.

Hydraulic puller sets

The ARX-8000SET pairs the 10 tonne ram with a 2 & 3-leg puller frame in one kit — the most common configuration for bearing, pulley, gear and coupling removal, where a mechanical jaw frame grips behind the component and the hydraulic ram draws it off the shaft under controlled, even force. It's a faster and safer alternative to improvised pulling methods (heat, hammers, wedges) on components that are pressed or corroded onto a shaft.

Choosing the right ram or puller set

With only two capacities stocked, selection mostly comes down to matching tonnage to the job with a margin in hand, then confirming the accessory set gets you the reach and contact geometry you need.

• Tonnage: estimate the peak force the job needs and choose the ram rated above that figure — running a ram at or near its rated capacity on every job shortens its service life and leaves no margin for a component that's more stuck than expected. Between the 8T and 10T, the 10T also opens up the wider ARX-8000 accessory range.
• Reach and stroke: check collapsed height against the working clearance you have, and confirm stroke length covers the full distance the component needs to travel — a ram extension (ARX-8014 or ARX-8015) is the fix if the base ram's collapsed height won't fit.
• Contact geometry: use the centre locator (ARX-8013) to keep force axial on shaft and bolt work, and the twin head (ARX-8012) where a single contact point risks damaging the component or won't seat properly.
• Pulling vs pressing: for pulling a bearing, gear or pulley off a shaft, pair the ram with a 2 & 3-leg puller frame (as in the ARX-8000SET) rather than pressing directly.

Where these tools get used

Hydraulic rams and puller sets in this capacity range are workshop and field maintenance tools first — sized for the bearing, bush, gear, pulley and coupling work that comes up regularly on plant, vehicles and equipment rather than for heavy structural or civil applications. Typical use includes mechanical and fleet workshops pulling and pressing bearings and bushes during routine servicing, industrial and manufacturing maintenance teams removing pulleys, gears and couplings from shafts, and agricultural and light plant maintenance where a compact hydraulic puller replaces slower, less controlled manual pulling methods. If your application calls for materially higher tonnage or a different actuation type than what's listed here, talk to our team — we can advise on fit or point you to the right alternative.

Trax — the brand behind this range

AIMS stocks the Trax ARX Series for this category — the 8T and 10T ram bodies and their matched accessory sets described above. If you need a specification, certificate or compatibility detail for a Trax product that isn't listed here, our team can chase it down with the supplier on your behalf rather than have you rely on a guess.

Working safely with hydraulic rams and pullers

Hydraulic rams apply very high force in a small space, and that force has to be respected. Keep hands and body clear of the load path — a ram or puller frame under load can release suddenly if a component lets go unexpectedly or a fitting fails. Check hose and fitting condition before use, and never exceed the rated capacity of the ram or puller frame. High-force pressing and pulling tasks generally fall within the scope of the model Work Health and Safety Regulations that Safe Work Australia coordinates across most states and territories, which call for the task to be planned and, where it's assessed as high risk, documented — worth building into your normal pre-use check rather than treating as a one-off. If you're setting up a puller job you haven't done before, our team is happy to talk through the safe way to rig it.

Hydraulic Ram & Puller FAQs

What tonnage hydraulic ram do I need?

Estimate the peak force the job requires and choose a ram rated comfortably above that figure rather than right at the limit — running a ram at its rated capacity on every job shortens its service life and leaves no margin if a component turns out to be more stuck than expected. AIMS stocks 8 tonne (ARX-7000) and 10 tonne (ARX-8000) rams; for anything outside that range, contact our team.

What's the difference between a hydraulic ram and a hydraulic cylinder?

In everyday workshop use the terms are largely interchangeable — both describe a piston-and-cylinder actuator that converts hydraulic pressure into linear force. "Ram" is the more common term for portable, high-force tools used for pressing and pulling, which is how it's used across this range.

Can I use one of these rams to pull a bearing off a shaft?

Yes — pair the ram with a mechanical puller frame that grips behind the bearing, such as the 2 & 3-leg frame included in the ARX-8000SET, and the ram draws the bearing off under controlled, even force. Pressing directly with the ram alone suits pushing a component on or off in a straight line where there's something solid to press against; pulling needs the puller frame.

What's the ARX-7088 hydraulic-to-mechanical adaptor for?

It's designed to let the ARX-7000 ram drive a compatible mechanical puller frame hydraulically, in place of the frame's own hand-cranked screw. Confirm compatibility with your specific puller frame before ordering.

What do the ram extensions (ARX-8014, ARX-8015) do?

They increase the ram's effective reach for jobs where the standard ram's collapsed height doesn't get you to the work — useful where clearance is tight or the component sits further back than the base ram can reach.

What's the centre locator (ARX-8013) used for?

It keeps the ram centred and square over a shaft or bolt so force is applied on-axis rather than at an angle. Off-axis force on a pressing or pulling job increases the risk of a slipped fitting or a damaged component, so it's worth using wherever the geometry allows it.

What's the twin head (ARX-8012) for?

It's a dual-contact head designed to suit YC101-type fittings, for jobs where a single-point ram contact isn't suitable — for example where you need to spread load across two contact points rather than one. Check fit against your existing puller hardware before ordering.

Does the ARX-8000SET puller set include everything I need?

It includes the 10 tonne ram and a 2 & 3-leg puller frame as a matched kit. Confirm exactly what's in the box — including whether a pump and hose are included — on the product listing or with our team before you order, particularly if you don't already have a compatible pump.

Are these rams single-acting or double-acting?

Single-acting rams extend under hydraulic pressure and retract under spring or gravity force once pressure is released; double-acting rams are powered in both directions. For the specific actuation type of the Trax ARX-7000 and ARX-8000, check the product listing or ask our team — we'd rather confirm it against the current spec sheet than guess.

What safety precautions apply when using a hydraulic ram or puller?

Keep hands and body clear of the load path, check hoses and fittings for damage before use, and never exceed the rated capacity of the ram or puller frame. High-force pressing and pulling tasks generally fall within the model Work Health and Safety Regulations that Safe Work Australia coordinates — plan the task and treat it as high risk if the assessment calls for it.

Does AIMS stock hydraulic oil and fittings to go with these rams?

Yes — see our Hydraulic Oil and Hydraulic Fittings ranges. If you need a specific pump or hose matched to one of these rams, contact our team and we'll confirm the right combination.
