There are large and distinct differences in the bearings that are used in dental hand piece repair. The bearing used can have a large impact on the drill's performance and your 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. This is the bearing retainer inside the bearing housing.
The angular bearing is fully contained, meaning the bearing rides inside the retainer. One advantage is the bearing can be pressed on either side of the bearing. The other is the retainer holds the bearing all the way around controlling where it rides with no play. This allows for better control of the forces inside the bearing such as centrifugal force and heat. The angular bearing is superior and worth the extra cost.
The largest single way to gain the longest time between repairs is to keep your drills maintained as per manufactures recommendations. Read the Hand Piece Post for maintenance instructions also.
The Radial bearing rides inside a crown shaped retainer and allows for up and down movement of the bearing inside the casing. This type of bearing is not suitable for high speeds and allows for vibration of the drill. Also the crown retainer can break allowing the bearings to touch. This is what causes the squealing in a defective drill.
Beware the low cost servicers. They save cost by using parts out of China, Pakistan, ect. These turbines can be purchased very cheap and will not last 30-60 days.
At Bauer we use American made Myonic bearings providing a superior repair. If you properly maintain your drills, these bearings can last a year and longer.
