Lubricant Failure = Bearing Failure

From Applied Industrial Technologies

Bearings rarely wear out, yet they do fail. Careful analysis of bearing condition and failure modes can provide insight into the causes of failure and how to correct them. In most cases, lubrication plays a role in bearing failure.

Thrust Bearings
Thrust bearings are designed for pure thrust loads, and can handle little or no radial load. The rolling element in a thrust bearing can be a ball, needle or roller.
Thrust Washers
Thrust washers are used as a bearing surface for rotary applications.  They are usually made of steel, bronze, plastic, or other material with low friction coefficients.
Cylindrical Roller Bearings
Cylindrical roller bearings have high radial-load capacity and moderate thrust loads. They contain rollers which are cylindrically-shaped, but crowned or end-relieved to reduce stress concentrations.
Hanger Bearings
Hanger bearings are used as rotational bearings for drive and screw conveyor shafts that are enclosed with a housing or trough.
Radial Ball Bearings
Radial ball bearings are friction reduction, rotation devices that carry loads radially around its axis. A subtype of ball bearings, they operate through the use of lubricated steel balls placed between two circular guides. They are frequently called deep-groove bearings.
