1 what is hydraulic cylinder stroke ?

The stroke is the amount of travel the piston rod can move in and out. It can be found by subtracting the maximum extended length of the hydraulic cylinder from its minimum compressed length.


2, what cause cylinders drift ?

Hydraulic cylinders drift is caused by internal leaks in the cylinder across piston. The fluid physically moves from one side of piston to the other which creates an uneven balance and causes the cylinder to move or drift.

3, what are the most common causes of hydraulic system failure ?

Air and water contamination are the leading causes of hydraulic failure, accounting for 80% to 90% of hydraulic failure.

Temperature problems

Fluid levers and quality

Human Error

4, what happens when air gets into a hydraulic system ?

Air in the hydraulic fluid makes a banging or knocking noise when it experiences high and low system pressures as it circulates through the system. High fluid temperatures above 180 are detrimental to system operation and will damage seals and accelerate degradation of the fluid.
