Application of heavy-duty bearing NSK bearings, must be combined with the characteristics of heavy-duty bearing to consider. Heavy-duty bearing work often in high stress state, and the bearing of high stress is very sensitive, all the links and application technology will strive to slow bearing stress, and stress mitigation is conducive to prolong the life of NSK bearings. For example, high loading machine in the axial position permitting, bearing a single fulcrum in the original doubled to two to bear radial load, and despite the impact load is uneven, the workpiece at the same conditions, the fulcrum of the two bearing life than the original single bearing conditions, is expected to increase more than two times. In fact, in the heavy machinery is often in a pivot point using a plurality of bearing or multi-row bearing radial load.
In order to stress slow heavy NSK bearing lubrication, want thicker films, so is the use of high viscosity high viscosity lubricating oil or grease oil as base oil, but also hope to ensure good lubricating conditions, due to friction moment not lubricant viscosity caused by too high.
Heavy-duty bearing rotating rings with the amount of interference than the general situation, which has adverse effect on the deformation of raceway and bearing life, therefore, where possible, to reduce the amount of interference, for reducing surface roughness, while maintaining the normal lubrication lubrication, because in the event of failure, overload under the raceway surface friction moment of the mating surface creep tendency, even in slippage, although these phenomena occurred in the outer ring, inner ring - but serious when also the inevitable. Pay attention to not appear too large gap with the outer reality, so as to avoid the oil into the surface, the slip phenomenon, and made the ring is easy to deformation, reduce the bearing area bearing.
Only take effective measures in detail, was allowed to reduce the heavy NSK bearing interference fit, and the amount of interference is slightly reduced, the bearing stress state improvement is larger, of course, thickened oil film will benefit more.
Due to the overloaded NSK rolling bearing surface contact area is large, with tight, ring close and deformation is large, so usually bearing clearance has made great.
