There is a guy on ebay, selling sealed bearings to replace the open-faced bearings on most Husqvarnas..this is what he says:
"The factory installs an open style bearing with an outer seal. This bearing usually fails due to condensation which builds up inside the case (which causes the bearing to rust) and the bearings to fail.
This seal also keeps the grease on the bearings (where it is supposed to be) thus making the bearings last longer. The design of the saw(s) have nothing to keep the grease inside the bearings on the inside of the case (open bearings ~ grease falls out ~ bearings fail!).
Also with these bearings you now do not have to use the factory outer seals."
....so anyone have experience with this type of application?
