RMQSI Answers ForumCategory: Non-Electrical Component Reliabilitymeaning of part numbers and data sources
Utku asked 7 years ago

Hi, I’m trying to learn how to use NPRD 2011 database via Windchill QS.
I dont know what part number and data source refers. Lets name it, NRPD-805 and NRPD-24148 are both ball bearings for airborne environment with mil-spec qualities. They have different data sources. How do I decide which one is more suitable? Which one reflects the bearing of the design in a better way? What data sources NRPD-106 or 25199-000 refers? There must be differences that I cannot see because operation speed, loading conditions are all important factors for bearing failure and I cannot see any specification on these.
Thanks in advance.
