Hey Everyone, Could someone point out how to lubricate, say, a jointerr’s bearing? I took a portion of the cutter-head apart (restoring a jointer), and it seems like there was grease or something in there between the bearing and the block that houses the cutter-head support. Is friction holding the bearing in place inside the housing, along with the cutter-head spindle inside the bearing or do I really need to grease everything in and around it? I’d appreciate any feedback.

It depends on the specific jointer. Most newer jointers would have sealed bearings that don’t require grease, and are actually impossible to grease. Older jointers that require grease will usually have a grease fitting.

Here are 2 images of this particular cutter head. The bearing doesn’t seem that bad, but there are a lot of caked on stuff inside, thus the possibility of buying a new bearing.

Those are sealed bearings, so no additional grease is needed. The bearing in the first picture doesn’t look to be in the best of shape, so I’d go ahead and put in new ones while you have it apart. No grease should be in the bearing housing.

Thanks for the help! I’ll get some new bearings and install them as-is.

Have your say...
