repacking new sealed bearings

[Paulos]

I've always pried the cover off new sealed bearings and packed with grease as they seem to come with a measly amount of grease when you buy them. 

A mate was told by the guy at the bearing shop not to do this though, as too much grease will cause the bearing to overheat and the small amount of grease in there is all you need.

I'm not too keen on this idea though. Any thoughts?

[Rossvickicampbell]

too much grease overpacked will cause overheating - however define too much grease?

[fred99999au]

The amount of grease in a bearing that causes overheating?

If you repack the bearing you can be assured of the the suitability of the grease for your particular application. Ask your bearing supplier if the factory grease is suited for your purpose at least. I suspect that the bearings are initially packed with a preservative type grease and I prefer to use quality wheel bearing grease ( if I am using the bearing for wheels) so I know it will be up to the task.

I've always packed one side of a new bearing with good water proof grease and they have lasted 5 years on an enduro bike. But on wheel bearing that were never packed they failed with in a few years. Do it

I always pop on seal and add some grease or a bit of moly lube or other slippery stuff.

What a crock of poo,
He should sell vacuum's.
Grease those suckers up.

I was taught when doing this on electric motor bearings to pack them 2/3rds full to stop overheating.On my bike wheel bearings I wash out the original Vaseline they come with and repack with Belray waterproof grease and as said by others they last for years.

If you are going to pack them always do it with the palm of your hand:

I know it says wheel bearings but use the same procedure on roller bearings. It's the easiest way to get the grease where it's supposed to be, just a bit messy..

[fred99999au]

Thats funny. That is how I was taught many moons ago.

[matcho mick]

yep,std procedure,tapered bearings sharp edges cleaned your palm up pretty good too, ,

[FourstrokeForever]

Yep, wash the vasoline out and repack with good quality wheel bearing grease. They will last for years, even longer if you do it every year or so.

I have one grease gun dedicated to do bearings, it has a large bore hypodermic needle as the outlet and I fill the centres between the balls, rods, and the opened side. With wheels I put the side I've opened inward incase the seal was damaged.

[Tony.Brown]

Now call me a cynic, but why would a person who sells bearings for a living tell you not to re-grease your bearings? I wonder?
