Precision bearings according to ISO grading standards are divided into: P0, P6, P5, P4, P2. Rank higher in turn, where P0 is the general accuracy, other grades are precision level. Of course, different classification standards, different types of bearings, their classification method somewhat different, but the meaning is to the. The use of performance requirements of precision bearings rotating body with high runout accuracy, high-speed rotation and small changes in friction and friction.

This load is Bearing Test Machine characterized by a relatively static radial load vectors and synthesis loop
Synthesis of radial load on the fixed load of the load from the local fixed ring raceway ring is exposed and sent to the appropriate local or bearing shaft . This load is characterized by a relatively static radial load vectors and synthesis loop . Bear the load ring , you can use a relatively relaxed. Synthetic <BR> rotational load of radial load applied to the full complement cylindrical roller along the circumferential Bearing manufacturer direction of the rotating bearing ring on the roller , turn the various parts , such as the rotation load , which is determined by the combined vector phase loop radial load rotation, bear . Work closely with the rotating load ring , in exceptional circumstances , load, if elected , is light or heavy loads , low speeds , and only occasionally rings , bearings hard materials and high slewing bearing surface roughness , rotating load bearing rings can also be used more loosely . Third load swing directional load or no load , the load ring radial direction of the uncertainties of the load, which is characterized by a ring raceway radial load vectors role of an impact load in a certain area , vibration, load , and its direction is the swing roller to bear a certain area , or acting on the bearing load , load values change frequently . To bear the load swing , outer ring and weeks , bearings, holes should close conjunction. <BR> Used to adjust the full complement cylindrical roller bearings radial clearance as follows : <BR> 1, for cylindrical and oval-shaped bearing backlash
