Spherical Roller Bearings 7. General Operating Cautions Pressed cages or machined cages are standard depending on the bearing type and dimensions. However, a standard cage may not be used under high speed specifications or in conditions under severe vibration or impact. When bearings are operated under small loads (about Fr 0.04Cor), or under axial loads only, prevent rolling elements from smearing by operating in conditions where Fa/Fr 2e. (Refer to the dimension table for the value of “e.”) This is most apparent when using large size spherical roller bearings due to the large roller and cage mass. Please consult NTN Engineering for further details. B-205
