what's the eye opener?
use correctly, maintain (a service listed component in all the mentioned cases) correctly, replace as required/instructed, no problem,..... fail to use, service, maintain or replace correctly expect trouble... irregardless of the application or materials.
"Use grease xyz on this component at xxx interval & inspect for wear" is as valid a design/maintenance procedure as "change oil with sae 30 at 10k intervals" or "change tyres when tread is below 1/16""
