Min motor L-10 bearing life for different types of pump applications

[hondashadow1100vt]

I am looking for information on industry recommended minimum L-10 bearing life for motor bearings as a function of application/service/duty (i.e., pump applications mostly). I expected that HI or API might have something on this but I seem to have come up relatively empty handed. I'd be grateful if anyone can point to any references that tabulate or outline this subject. Thank you!!!

I think at least one of the API Pumps standards talks about minimum design L10 life.

Something like this -
"The API Standard 610 requires a minimum bearing life (L10) of 25,000 hours with continuous operation and rated conditions and at least 16,000 hours at maximum loads and speed."

snitched from here and not fact checked -

https://www.reliableplant.com/Read/...dard 610 requires,at maximum loads and speed.

Putting a required L10 life on the spec is only part of what's needed.
Poor Sealing can EASILY kill the L10 life.
Providing Sealing to beat the L10 life is not a lot harder, but requires more thought.

Ditto for lubrication choice and management.

-----------.

This FAG / Schaeffler publication is pretty handy - wl_00200_6_de_en.pdf

Google finds it quick.
