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.

Damage Analysis for Linear Guides

23/5/2012· Pitting in the raceway, dents, corrosion, tribocorrosion and electrical corrosion are some typical of damage that can occur when operating linear guides; and each type has a different cause. If a damaged profile is visible to the naked eye or a component has failed, the first step is to classify the damage so that its root cause can be identified.

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.
