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.

The Best Reasons Why Roller Chains Fail and How to Prevent Them - Mentored Engineer

It is critical to identify the failure mode and eliminate the cause. Overload, fatigue, rust and high speeds coined with small sprockets are the four main reasons roller chains fail. Overload and fatigue can be caused by galling, shock loading, misalignment or loads that are too high. A 10:1 safety factor is recommended.

Choosing the right bearing - Buying Guides DirectIndustry

Choosing the right bearing. Like plain bearings, rolling-element bearings reduce friction in a rotating guide between two parts. Depending on the direction of the force, axial or radial, there are different types of bearings. Bearings are composed of rolling elements, usually balls, cylindrical or tapered rollers or needles.
