Lubricant Failure = Bearing Failure | Machinery Lubriion

Inadequate flow in a circulating oil system can cause failures of tapered roller bearings. The area between the guide flange and the large end of the roller is subject to sliding motion and is more difficult to lubrie than areas under rolling motion. Therefore, some of the rollers can weld themselves to the guide flange.

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.
