What Is a Hollow Plunger Hydraulic Cylinder?

The hollow plunger hydraulic cylinder is a specialised member of the single acting cylinder family that solves a specific geometric problem: how to apply high force along the axis of a fastener, tie rod, or structural element while the element itself passes through...

How to Calculate Hydraulic Cylinder Speed

Hydraulic cylinder speed calculation is the step that connects bore specification, pump selection, and line sizing into a complete system design. A cylinder that generates the correct force but extends too slowly fails the application just as surely as one that is...

How to Order a Custom Hydraulic Cylinder

Custom hydraulic cylinder orders are straightforward when the specification is complete and well-communicated. Delays and incorrect deliveries almost always trace back to ambiguous or incomplete specifications rather than manufacturing errors. This guide covers the...

Why Does a Hydraulic Cylinder Extend Slowly?

A hydraulic cylinder that extends sluggishly or noticeably slower than its rated speed is signalling a problem somewhere in the system — rarely the cylinder itself. Extension speed is determined by the flow rate reaching the cylinder and the bore area. When speed...

Why Does a Hydraulic Cylinder Not Retract?

A hydraulic cylinder that extends but refuses to retract brings operations to a complete stop. The failure mode is highly specific — it tells you immediately that the extension function is working normally, which means pressure and flow are reaching the cylinder and...
