Contributes to the high efficiency and high output of rotating machinery with direct lubrication! Improves load capacity while reducing oil supply and loss horsepower!
Kingsbury's "LEG Direct Lubrication" oil film bearings are a high-efficiency type that directly supplies lubricating oil to the pad surface. Not only does it achieve significant reductions in oil supply volume and loss horsepower (mechanical loss) compared to conventional oil sump types, but it also realizes lower pad surface temperatures and increased load capacity compared to other direct lubrication methods. The LEG type oil film bearings include thrust bearings and journal bearings in their lineup. 【Features】 (*For LEG thrust bearings) ■ Pad surface temperature decreases by 8 to 28°C compared to conventional types ■ Load capacity increases by 15 to 35% ■ Lubricating oil volume decreases by up to 60% ■ Loss horsepower (mechanical loss) is also reduced by 45% It is possible to upgrade not only new rotating machinery but also the efficiency and load capacity of currently operating rotating machinery by replacing existing bearings with LEG type oil film bearings while maintaining the same bearing size.
