There are large and distinct differences between which bearings that are used in dental handpiece repair. The bearing used can have a large impact on performance and budget.
There are two types of bearing other than physical size and exterior design. What I mean by exterior design is flanged or smooth bearing exterior.
For the purpose of this discussion we will examine the difference between the radial and angular bearing. The radial retainer holds the bearing in a crown, or claw like pattern. When this bearing fails one of the retainer claws will break and you get that familiar squeal. This is result of the bearings hitting each other.
The angular bearing is fully contained, meaning the bearing rides inside the retainer and is the best and most expensive. A large advantage of the angular bearing is that it will typically last longer at the higher speeds of the high speed hand piece. When used with the ceramic ball bearings inside the angular retainer we have a superior bearing.
The largest single way to gain the longest time between repairs is to keep your drills maintained as per manufactures recommendations. I would recommend you discuss your options with your dental hand piece repair service company to get the best benefit for your practice.
We always use ceramic bearings with the angular retainer. This is a superior retainer and will resist the heat of autoclaving the best.
