A hydraulic cylinder that will not extend has stopped receiving the pressure, flow, or mechanical clearance it needs to move. Unlike a slow-extending cylinder — which is a degree of the same problem — a hydraulic cylinder that will not extend at all provides a very...

A hydraulic cylinder that loses pressure — allowing a raised load to drop gradually, a clamped workpiece to slip, or a pressed component to spring back — has a bypass path somewhere between the pump and the load. Finding that path requires distinguishing between...

Bleeding air from a hydraulic cylinder is a straightforward procedure when the correct technique is used — but skipping it after installation or maintenance produces a system that performs poorly from the first operation and may damage seals within hours. Air trapped...

A clevis mount hydraulic cylinder has a forked clevis bracket at the cap end — and often at the rod end as well — through which a mounting pin passes, allowing the cylinder to pivot freely as it extends and retracts. This pivoting capability is the defining feature of...

Choosing the best hydraulic cylinder for a pressing application requires matching the cylinder type, bore size, stroke, and mounting to the force, geometry, and duty cycle of the specific press. Pressing is one of the most force-intensive hydraulic cylinder...

Hydraulic oil is the lifeblood of a hydraulic cylinder system — it is simultaneously the power transmission medium, the lubrication film that protects seals and metal surfaces, and the heat transfer fluid that carries waste heat from cylinders and valves to the...
