Application: Autoclave Bogie Wheel Assembly

A customer was experiencing constant bearing failure within an Autoclave bogie wheel assembly, using Deep Groove Ball Bearings. The failures resulted in damage of surrounding hardware (housings and axles) and high labour and parts cost, as components  needed regular replacement. NSK Engineers examined the application and determined that ingress of hard particulates and moisture, combined with excessive load was the root cause of premature bearing failure. NSK recommended changing to NSKHPS Spherical Roller Bearings, which gave better service life and greater reliability, as NSKHPS roller bearings carry greater loads and operate at higher temperatures. This resulted in eliminating continuous ongoing contractors maintenance and substantially reducing colateral damage to surrounding components.
