One of the keys to maximizing the service life of hydraulic components is to ensure that internal sliding parts are adequately lubricated to minimize friction and wear. Depending on the nature of the lubricated contacts, “adequate lubrication” ideally involves separation of the two sliding surfaces by a film of oil, known as full-film, or hydrodynamic lubrication. Forming and maintaining hydrodynamic lubrication depends on surface geometry, speed, load, and the viscosity of the lubricant....
