Spalled Bearings - Machinery Lubriion

This case history describes a macropitting failure (sometimes called spalling) that occurred on a rear axle pinion bearing. Macropitting over a sector of the inner ring (IR) of a tapered-roller bearing is not unusual, even with a rotating IR. This type of damage can be caused by a load that rotates with the IR such as a force due to unbalance.

Double row tapered roller bearings | SKF

Double row tapered roller bearings provide a stiff bearing arrangement. The optimized roller end design and surface finish on the flange ( fig. 3 ) promote lubricant film formation, resulting in lower friction. This also reduces frictional heat and flange wear. In addition, the bearings can better maintain preload and run at reduced noise levels.

Tapered Roller Bearings - an overview | ScienceDirect Topics

If a radial load is imposed on the bearing an axial load is induced and this must be counteracted by another bearing; it is normal therefore to employ two tapered roller bearings at each end of a shaft system to balance the loads or to use a bearing with two rows of rollers tapered in the opposite directions, as shown in Figure 10.20.
