What type of grease for high RPM fans?
What type of grease for high RPM fans?
(OP)
Hello.
I'm looking for a low viscosity grease that is suitable for sleeve bearings on high RPM fans. I have this high temperature lithium based grease which has viscosity around 100 mm²/s (cSt) and temperature range of up to 150°C. It's being advertised as a grease for electromotors. But it seems that it reduces rpm on smaller and high rpm fans.
What other lower viscosity grease could you recommend for this purpose?
Could I try white lithium grease with PTFE (teflon). Is it suitable for long term lubrication and high temperatures?

Much higher on the list would be the use of Kryotox, Fluorocarbon Grease

I don't have a large choice of products where I live so I could use a tip as to what kind of grease I should look for. For example, white lithium grease with PTFE is available but I don't if it is suitable for long term lubrication of fast spinning equipment.

I've never had any any Eureka moment using micronized Teflon additives in oil and grease.
Not all fluorocarbon base lubricants are created equal. We have had very good results using lubricants from Nye. Sometimes a pricey but well worth it to solve a lubrication problem.
It's the same as putting $2.00/gal oil in your car instead of the needed $8.00/gal.

Link to the SKF LGHP 2 datasheet

It's supposed to be gel like substance, not sure.

I think I might be able to buy either LGHP 2 or LGLT 2.
