thought it was fine but wanted some other opinions
I packed in white lithium grease into a large motor bearing (58mm), they’re SKF and didnt have much grease in them. I filled it 90% full, its pretty hard to move, and has no free spin at all. Not like it free spun before i put the grease in, but i can feel the resistance from the grease. The stock crap bearing has decent free spin
Just wondering if this would cause any unwanted friction or increased motor temperatures. Or am i overthinking?
Nobody knows at this point, wear it in
Also, pics
Grease is usually high temp but too much and youll be swimming in mud lmao.
Edit: i notice that friction ruins the esk8 experience
Huh, I never even noticed
IME, wheel bearings don’t really have any issues from overpacking.
But the few times I’ve tried to service motor bearings ( not in Esk8, just in general ) they seemed a lot more picky about it, and about everything else.
I probably would not be using WLG for a motor bearing, for that I’d make sure Id make sure I’m using a grease that has motor bearings listed among its applications. The Moly 274 grease I like does mention electric motors in its technical data sheet, as do many even generic greases, but I might even still look for something especially targeted towards motor bearing applications.
As for overpacking itself, I’m sure excess grease will work its way out pretty quickly so I don’t think that will do any harm for the bearing, but excess grease being flung around your motor is probably not good. Will attract dust and junk for sure.
Selecting the right grease is a science on its own. Read this, and you’ll be able to make a more informed decision.
For me, the free roll, the battery life, the temps, the sounds… its best to avoid friction
It was sarcastic lol
I used the same grease in my motors, but with a dab or two of red’s speed grease mixed in to it. That way it had the same thick consistency as the grease I removed (thick) but had less rolling resistance than just the WL grease alone.
I originally packed it full but ended up removing some/ it came out on its own while testing the bearing. It has been several months since replacing the grease in all of my motor bearings and I haven’t had any issues with them.
