1.4.2 Ball Bearings versus Roller Bearings Generally speaking, when comparing the same size ball and roller bearings, ball bearings exhibit lower frictional resistance and lower face runouts than their roller bearings counterparts. This makes ball bear-ings more suitable for use in applications where high precision, low torque and low vibration are

on the surface of a ball/roller bearing. Peeling can occur when the surface roughness is high, or when the lubrication performance is poor. Peeling has a flat-colored appearance, and when observed under a microscope, shows minute flaking and cracks. The top photo shows an example of minute flaking interconnected with cracks.
This phenomenon is called flaking. The total number of bearing rotations until flaking occurs is regarded as the bearing "(fatigue) service life". "(Fatigue) service life" differs greatly depend-ing upon bearing structures, dimensions, mate-rials, and processing methods. Since this phenomenon results from fatigue
