Wheel Bearings

Hillclimb#42:
Recently made a discovery. I just had to replace the wheel bearings in the 250. I was kinda whining about just buying them and the guy at the local bike shop told me a good one. He said that he always pops bearings open and fills them with grease. They last ten times longer that way. I was like, "thats a sealed bearing" he said that its just a rubber seal and to pop them out with a pick-like tool.

There they were. New Bearings, No grease. The seals pop off easy and both inside and outside can come off just as easy as the other. Neither side of my All Balls bearings were greased. Can anyone tell me why they would be absent of grease? Thought I would pass it on. :wink:

BDI:
I thought all sealed bearing came pregreased. I know they don't have a ton of grease because there is no benifit to over greasing bearings. To much grease can cause other probs in my opinion.

kaw rider:
kyle   those bearings need to be service very often. we have removable covers to make the job easyer.

Mine may have had a greasy film on them, but I could not say they were greased from the factory. None was apparent to the naked eye. I had always greased the lips of the seals, the axles, and even the collar/spacer deal in the middle. I have never tried to grease a sealed bearing. I'm still learning... :-D

maddoggy:
a bearing that is lubed by grease must not be filled past 1/2 way with the proper grease. overfilling with grease results in churning which develops excess heat. heat + bearings = spalling or other bearing race damage. trust me, i have been trained by timken bearing company.
