Values for the limiting speed are listed inthebearing tables. Thelimiting speeds in the tables are applicable to bearings of standard design and subjected to mormal loads, (c/p≥12 and Fa /Fr≤0.2) approximately. the limiting speed for oil lubrication listed in the bearing tables are forconvemtional oil bath lubricatiom. When speeds are more tham70%of the listed limiting speed, oil or grease used in bearing lubrication must have high speed characteristics.
