I started hearing a noise from my 3 year old Delta DC-380 15″ planer that I eventually traced to the plain bearings on the infeed and outfeed rollers. After removing the rollers I found that one of the bearings on each of the rollers was virtually frozen in place. After much work I was able to get them apart, clean them up and now they are moving freely. I put it back together with light weight grease and now it is working fine. It looks like these bearings are meant to be lubricated while in place since there is a hole in the spring tension bolt and a hole in the top of the bearing where you could apply some oil. Unfortunately, it doesn’t mention any of this in the owners manual. Has anybody else encountered this problem and what type of oil would you recommend? Thanks.

A light machine oil is usually what is used on that type of a bearing, a hardware store should have something in a small can. Apply a few drops once a month, maybe more often if you use the machine a lot.

Thanks, I was talking to a friend who is a professional woodworker about this situation and my dismay that you spend around $1500 on a machine and you would expect the owners manual to be more detailed. He said it didn't get any better for $20,000 dollar machines either, oh well.
