Hydraulic Rams & Tools

Hydraulic Rams and Hydraulic Tools

Hydraulic rams and tools use the mechanical advantage of hydraulic pressure to apply very large forces in a compact package — far exceeding what is achievable with mechanical tools alone. Applications include pressing and pulling bearings and bushings, straightening and forming structural components, lifting and positioning heavy machinery, splitting logs, and bending pipe and tube. AIMS stocks hydraulic rams, cylinders, hand pumps, and integrated tool sets from leading high-force tool brands for industrial maintenance, fabrication, and engineering applications.

Hydraulic Cylinders and Rams

Hydraulic cylinders are the force-generating element of a hydraulic tool system, converting hydraulic fluid pressure from a pump into linear mechanical force. Single-acting cylinders extend under pump pressure and retract under spring or gravity load — they are the most common type for pressing and lifting applications. Double-acting cylinders extend and retract under hydraulic pressure, providing controlled force in both directions for forming, straightening, and positioning applications where controlled retraction force is important. Cylinder capacities range from a few tonnes for light workshop use up to several hundred tonnes for heavy structural and industrial applications. Stroke length and collapsed height are critical parameters when selecting a cylinder for a confined installation.

Hydraulic Hand Pumps

Hydraulic hand pumps provide the pressure source for portable hydraulic tool sets and are available in single-speed and two-speed configurations. Single-speed pumps advance the cylinder at a constant rate per stroke. Two-speed pumps include a high-speed low-pressure mode for rapid advance and automatically switch to high-pressure low-speed mode when the cylinder meets resistance, which is more efficient for most pressing and pulling operations. Air-driven hydraulic pumps are available for high-cycle applications where hand-pumping would be fatiguing. Always match the pump's maximum pressure rating and oil capacity to the cylinder being used.

Bearing Puller and Press Sets

Integrated hydraulic bearing puller and press sets combine a hydraulic cylinder with a range of adaptors, claws, and support plates to handle a wide variety of bearing, bushing, and gear pulling and pressing operations. A quality hydraulic puller set eliminates the need for improvised and potentially dangerous pulling methods and significantly reduces the time required for bearing replacement in heavy equipment maintenance. Sets rated from 10 to 50 tonnes cover the majority of maintenance applications in workshops servicing mobile plant, agricultural machinery, and industrial equipment.
