Frequently asked questions (FAQs) for Hydraulics

Hydraulics is a mechanical function that operates through the force of liquid pressure. In hydraulics-based systems, mechanical movement is produced by pumped liquid, typically through hydraulic cylinders moving pistons.

Hydraulics allows machines to transmit force from one point to another using an incompressible fluid. In most cases, this also increases the force applied at one end for a given amount of effort. Hydraulics work on the same principle as the mechanical lever, a simple machine that functions like a seesaw

They are available as oil-in-water emulsions, water-in-oil (invert) emulsions, and water-glycol blends. Water-based fluids can provide suitable lubrication characteristics but must be monitored to avoid problems.
