For the future of our planet environment The Evolution of Rolling Bearings The technology of “moving” and “rolling” LFT-Series Low-Friction Torque with as little resistance as possible has evolved since ancient times as an eternal theme, blossomed as bearing technology and continued to evolve. LFT-Series JTEKT, since its time as Koyo Seiko, has constantly focused on friction and lubrication in efforts to reduce bearing torque and, in the 1980s, successfully developed the world’s first low-torque tapered roller bearing, the LFT. New generations emerged as the product evolved - LFT-II, III and...

Super-Low Friction Torque Tapered Roller Bearing (LFT-IV) Low-Friction Torque Ball Bearing In order to optimally control the amount of lubricant that flows through the bearing, this bearing uses resin with a high degree of design freedom for its cage material and has reduced lubricant mixing resistance. Bearing life in contaminated oil has also been improved Fast - Horizontal deployment of structure used on super-low friction torque tapered roller bearing to control oil inflow - By optimizing cage and inner /outer ring shape, oil flow to bearing is restricted and mixing loss is reduced by up...
