Initially ceramic bearings were sold to the hand piece repair technician as not needing any lubrication because they are pre lubricated and sealed. Because of this we were selling them to you as no lube bearings. They do last longer than the stainless steel bearings used in the past. However most sealed ceramic bearings that I see in my repairs are lasting between one to six months.

I have one client Ceramic Repair Guys that does not lube their hand pieces. With stainless steel bearings their repair would last about four to six weeks. After converting them to ceramic bearings their service rate has increased to six to seven months. However this can vary greatly depending on brand and usage. These clients are getting much more time between rebuilds using the same bearings and the same drills.

This is just a bit more work but if you can cut your rebuild expenses in half it is well worth it. I am recommending this procedure to all of my clients. I have some thoughts about why. Inspecting the bearings that are failing prematurely, I am finding the seal on the bearing is warped slightly allowing the lube to be released. The “O” ring in the head of the hand piece is hard and sometimes allowing air to leak through. Is it likely that the air pressure is being adjusted to compensate for a bad “O” ring in the hand piece.

The answer is, If you go to the manufacturer and purchase the original turbine you will pay dearly for it. This is because the original bearings are of superior quality and are manufactured to the manufacturers specifications. The bearings that the manufacturer uses are made by the same companies that we purchase from. However the manufacturer has rights to the specific bearings they use so they can be supplied to you at a higher cost. The after market bearings are also high quality but are less expensive so a rebuild is affordable.

The typical after market rebuild is about a third the cost of what the manufacturer will charge you. If you lube your bearings and use the drill at the correct air pressure there is not much difference in reliability between original and aftermarket bearings. The best procedure seems to be to put three or four drops of hand piece oil in the air hole and one or two drops in the chuck. Then run the hand piece until all oil is expelled. Next sterilize and then lube it again before storage.
