Needle roller bearing RAX series

radialaxialsteel

When the applied axial loads are relatively high and the application allows the use of oil as the desired method of lubrication, bearing types RAX 500 should be given consideration. Combined bearings with a dust cap may use oil lubrication, although their design makes them better suited for use with grease lubrication. Combined bearings are typically shipped protected with a corrosion preventive compound that is not a lubricant. The bearings may be used in oil or grease lubricated applications, without removal of the corrosionpreventive compound. However, it may be advisable to remove the corrosion-preventive compound before packing the bearings (with a suitable grease) to obtain optimum grease performance and to minimize the possibility of confusing grease bearings with bearings containing corrosion preventive. LOAD RATINGS Calculations for combined bearings are carried out taking the axial component and the radial component separately without transforming the axial load into an equivalent radial load. For the meaning of the Load Ratings in the tables of combined bearings RAX 400, RAX 500 and derivatives, see the Technical Section. Combined bearings type RAX700 and RAXF700 has a limitation for the maximum axial permissible load, both axial and radial, because are made in thin outer ring.
