How do you size a vacuum cup?
Vacuum cups grip a workpiece by evacuating air from the space inside the cup, creating a partial vacuum at a pressure below ambient. In simple terms one can…
How do you select a vacuum cup?
When it comes to gripping and moving anything from cola cans to car fenders, vacuum cups on end-of-arm tooling are incredibly versatile devices in many automated handling systems….
What is viscosity index?
Viscosity index is a dimensionless number that represents how the viscosity of a hydraulic fluid changes with temperature. (It also applies to fluids like engine and automatic transmission…
Why is viscosity important in hydraulic fluids?
Viscosity, according to Webster’s Dictionary, is the property of fluids and semi-fluids that defines its internal resistance to flow and shear. Or, in more simple terms, how thick…
How hydraulic fluids affect energy efficiency
The fluid is a key part of any hydraulic system. It transmits power, lubricates components, transfers heat, acts as a sealing agent, and helps minimize the harmful effects…
How does extreme cold affect hydraulic hose?
