NTN 689 bearing are suitable where: NTN 689 bearing arrangements are subjected to high and very high radial loads relatively high axial loads occur on one or both sides, in addition to high radial forces dynamic or static misalignments of the shaft relative to the housing, or deflections of the shaft, must be freely compensated by the bearing high shock type loads must be supported dynamically locating bearings with a very high load carrying capacity are required.
Long service life, high reliability, minimized maintenance and the ability to design compact arrangements have made NTN 689 bearing indispensable in many industries. In addition to the industrial segments listed above, NTN 689 bearing are also used in bridges, dam gates, electric motors, gener ators, plastic calenders, extruders, printing machines, robots and many other applications.
