9. arolina USA Catalog HY09 SM500 US Hydraulic Oil Recommendation Hydraulic Oil Recommendation When choosing your Hydraulic Oil duty cycle and oil tem perature must be factored in to optimize your system perfor mance Since hydraulic systems often work under extreme temperature changes especially in moderate to severe duty cycles the lubrication qualities of the oil in tight tolerance components is even more critical Viscosity choice is always a compromise the fluid must be thin enough to flow easily but thick enough to seal and main tain a lubricating film between bearing and sealing surfaces This film of oil helps to reduce friction and heat which can ultimately lead to component damage Fluid temperature does affect viscosity When choosing a fluid it is important to consider the start up and operating temperatures of the hydraulic system In general as the fluid warms it gets thinner and its viscosity decreases At the highest temperatures the fluid must be thick enough to pro vide lubrication and minimize internal leakage Low viscosity leads to the following problems e Higher leakage across all sealing gaps in the pump leading to lower volumetric efficiencies and heat e Heat will cause loss of lubrication and will create severe wear because of metal to metal contact causing prema ture failure of the gears thrust plates and bushing blocks PGP PGM500 Series Service Manual The opposite is true when the fluid
