Many fields of engineering now call for the speed of spindles to be raised beyond the values quoted in the rolling bearing catalogues. To meet this requirement emphasis is placed not only on the design of the bearing assembly but also on the correct type of lubrication system. Conventional lubrication systems fail in these cases due to friction related losses & the temperature rises beyond the permissible limits due to the hydrodynamic losses in the lubricant. Air/oil Lubrication is based on the principle that a drop of oil is split by the air flow, dispersed in streaks, & transported in the direction of the air flow, this ensures that a continuous flow of lubricant arrives at the outlet where it is compressed in the nozzle and fed to the friction point in droplet form. The oil remains at the friction point & the air, which unlike oil mist lubrication is oil free can escape into the atmosphere, the air provides a seal from outside contamination and also reduces the temperature in the bearing.
