Loading Degree of Grease

1.The standard loading degree of grease is 25%~35% of bearing inner space A: Less than standard loading degree B:Less than standard loading degree C:more than the loading degree of B According to the running speed the grease loading degree as follows 1/2~2/3 of space...When the speed is less than 50% of the limiting speed 1/3~1/2 of space: when the speed is more than 50% of limiting speed
