Compact Hydraulic Cylinders

With a small body size, these cylinders fit into tight spaces but offer similar push forces to standard hydraulic cylinders. They’re double-acting cylinders, so they have two hydraulic ports—one to extend the piston rod and another to retract it. No matter the direction they’re moving, they can operate at nearly full force. This allows them to both push and pull multi-ton loads. All have a magnetic piston and can be used with sensors (sold separately) that electronically indicate piston position. Mount sensors to the cylinder with mounting brackets (sold separately).

Double-Ended Compact Hydraulic Cylinders

Push one heavy load while pulling another. These hydraulic cylinders have a rod that runs through both ends, so when it extends on one end, it retracts on the other. Built with a small body, they'll fit in tight spaces but operate with similar force to standard-sized hydraulic cylinders. This is in large part thanks to their two hydraulic ports: one port to extend the rod and another port to retract it. That means no matter which direction they're moving, they're giving it the same amount of power.

The piston is magnetic, so you can use these cylinders with sensors (sold separately) to activate relays and controllers. When the piston moves past a sensor, the sensor activates. You can use multiple sensors—one for each action you want to trigger.

Pumps for Hydraulic Jacks

(2) Manual Pump

Connect these pumps to a ram to create a hydraulic jack. Use hose to connect; add a pressure gauge to monitor hydraulic oil pressure levels and guard against overload.

To use Style 1 and 2 pumps vertically, point the pump head (where the handle meets the pump) downward. Style 2 pumps are made of aluminum, making them lighter and more corrosion resistant than steel and iron pumps.

Pumps with two-speeds are quick to pump until the load is engaged, then pump more slowly for precise positioning.

Warning: Never use to support people or loads over people.

Air to Hydraulic Power Converters

Power a hydraulic cylinder from your air system to avoid the setup, cost, and mess of hydraulic fluid. These converters amplify air inputs to operate hydraulic cylinders. This gives you greater force and more consistent power than using air power for an air cylinder. However, because air works at a lower pressure than hydraulic fluid, your hydraulic cylinder won’t move loads at its full force. Attach these converters to an air line with a speed controller and solenoid (not included).They must be installed top-down.

Note: These converters are not for use near fire.
