This work reviews the failure modes, mechanisms and causes of bearings in mechanical
equipment. Bearings are among the most important basic mechanical components. Their …

The spherical plain bearing is an important basic moving component which is widely used in
aerospace and industrial equipment. However, current studies are predominantly conducted …

This study presents a novel and non-destructive method for quantitatively analysing grease
lubricated bearing wear by using X-ray microcomputed tomography (μCT). The efficacy of …

The inter-shaft bearing is a critical but vulnerable component of dual rotors, because of the
severe operational conditions and loads. This paper investigates the failure mechanism of a …

Abstract Polyamide 66 (PA66) is used for polymer sliding parts, and to increase its strength,
reinforcement fibers such as glass fiber (GF) and carbon fiber (CF) are often added. Using …

Acoustic emission (AE) is used for the condition monitoring and fault diagnosis of various
components like gear, bearing, machine tool etc. The experimental studies have been …

In this study, the reactive extrusion mechanism of fiber-reinforced polyamide 66 materials
with added carbodiimide was clarified, and the mechanical and tribological properties of the …

Rolling-element bearings are the most commonly used components in all rotating
machinery. The variations in the operating conditions such as an increase in the number of …

Polyamide 66 is widely used for sliding parts that are in contact with steel under grease
lubrication, including worm gears or bearing retainers. To meet the requirements for …

Polyamide 66 is widely used for sliding parts, such as resin worm gear. Glass fibers are
usually added to increase its strength. In this study, the tribological behavior of glass fiber …
