Fluid viscosity is one of the factors that determines whether full-film lubrication is achieved and maintained. If load and surface speed remain constant, but elevated operating temperature causes viscosity to fall below that required to maintain a hydrodynamic film, boundary lubrication occurs; this creates creating the possibility of friction and adhesive wear. On the other hand, there is a viscosity range where fluid friction, mechanical friction, and volumetric losses are optimal for hydraulic system perform… Please note that the job can be quite tricky, especially for first-timers and novice owners.
