Grease is oil that melts with heat. It last because it does melt and it is not necessarily the best.
I was simply trying to clarify what grease actually is without taking a position on how bearings should be lubed.Mitch, are you saying you feel its better to use the grease in the bearings instead of just relying on the ball oilers to keep the bearing lubricated?
The reality is that no one will be oiling their wheel bearings daily or even yearly. Plus because there are grease seals it keeps the grease in.Ahh, ok. yea, I was just trying to clarify. I am about to change the spindle bearings on my lathe and have had some people say to grease them but grizzly says to just use oil and put oil in the ball oilers when using the lathe, as usual. Trying to decide if I should use some grease or not. Considering Grizzly recommends not to and your general rule of using oil on things that roll it kinda sounds like I should just use oil. Thing is I know that wheel bearings in cars are supposed to be packed with grease also, but then again it could be because that is alot of force on wheel lbearings so maybe thats why they use grease.. like you say there is always exceptions. Probably considering everything it wouldnt be a big deal either way you chose to do it... decisions, decisions.

For the G0602/KC1022/other variants, ISO32 oil is called for by Grizzly et al. Oil each day before you use the lathe and all will be well.
