There are 2 places on the ends of my blower cage for furnace I think it has bearing inside well there is a place to put oil or greese by flipping the small caps up what goes in there my furnace si making a noise when the pully turns the cage. The thing I'm talking about are on the ends of the shaft that turns the cage

Oil is what goes into the small caps. Just a few drops will do in each cap. Now the things you are talking about are bearings and if they are defective no amout of oil will save them.

Thanks I will put oil in .is spf10 the correct oil?

If its 10 weight it will work. Actually I use turbine electric motor lube for everything unless I have a problem then I go for the Zep 45 that stuff is super slick and lasts a long time.
