In the railroad industry, distressed bearings in service are primarily identified using wayside
hot-box detectors (HBDs). Current technology has expanded the role of these detectors to …

Bearing steel cleanliness is of primary importance due to potential failures caused by rolling
contact fatigue (RCF). Bulk material ultrasonic scanning provides a method of assessing …

Steel cleanliness is of the utmost importance in the production of tapered roller bearings
used in the railroad industry. Impurities in the steel can make it vulnerable to fatigue initiation …

In the rail road industry damaged bearings in service are primarily identified by using
wayside hot-box detectors (HBDs). In general if the temperature is greater than 105.5oC the …

This paper deals with fault detection and diagnostics of freight rail tapered roller bearings
using statistical features and auto-regressive m. odel parameters extracted from bearing …

One of the main concerns troubling railroad bearing manufacturers is the unexplained
abrupt increase in the operating temperature of a healthy (defect-free) tapered-roller bearing …

A series of laboratory experiments have been conducted at the University of Texas-Pan
American in collaboration with Amsted Rail to investigate the root cause of bearing" …

An on-track collaborative field test and laboratory experiments were conducted in order to
determine the relationship between abrupt rises in surface temperature of a railroad bearing …

The understanding of the phenomenon of temperature trending of railroad tapered roller
bearings is of paramount importance to the railroad industry. The problem that this poses to …

Catastrophic bearing failure is a major concern for the railroad industry because it can lead
to costly train stoppages. Excessive heat buildup within the bearing is one of the main …
