Ceramic bearings are the best for dental high speed handpiece

High-speed dental handpiece are an important piece of equipment in daily dental procedures, with rotation speeds up to 4,00,000rpm/min. Bearings within these handpieces support the burs, allowing them to cut teeth faster during dental procedures. Bearings are critical to the operation of the dental handpiece. Therefore, failure to use high-quality bearings can lead to surface wear and eventually dental handpiece failure.

1. What are the bearings used in dental handpieces?

Bearings for dental instruments come in many shapes and materials, resulting in a wide range of quality and price. Dental bearings are of high quality for precision, accuracy and reliability. There are two types of bearings according to shape - radial contact bearings and angular contact bearings. These radial bearing bearings have an advantage because these bearings can be loaded axially from either side, whereas angular bearing bearings can only be loaded from one side, but with greater loads.

Similarly, depending on the materials used, there are two types of ball bearings used in dental handpiece. The first is a ceramic bead, which consists of a steel ring inside. The second type is a steel ball, which also has a steel ring inside. Using ceramic bearings offers several advantages over steel ball bearings. The biggest advantage of using ceramic bearings is that the movement runs cooler, which extends the overall life of the bearings.

Various studies have been carried out on ceramic ball bearings which have shown that they are 60% lighter than stainless steel balls. Due to the lighter weight, it is easier to hold the handpiece, and the centrifugal force generated when running at high speed and full speed is also significantly reduced. This improves overall efficiency and minimizes overall wear on the outer race. Due to the very low weight of the bearings, overall surface wear is reduced. Additionally, ceramic balls have a harder outer core, so there is very little chance of contamination or debris causing bearing failure. Dental equipment with hybrid ceramic ball bearings are also quieter and require little lubrication due to their friction-free nature.

2. The advantages of using ceramic ball bearings compared to stainless steel bearings

Compared with stainless steel bearings, dental handpiece with ceramic ball bearings have a longer service life, higher speed, no heat when the handpiece works, and lower noise. Dental handpieces using ceramic bearings are not adversely affected during assembly.

3. Ceramic Ball Bearing Dental High Speed Handpiece

This is a uniquely designed dental handpiece assemble with Germany ceramic bearings for longer life. Big power, low voice. The body is made of titanium alloy, and the whole handpiece is light in weight, the bur fixing mechanism is designed to securely hold the bur in place even under high torque loads, and updated technology provides greater smoothness Spend. It has a mini head so it can be easily used in the rear area, and adds the advantage of ceramic bearings, making it a lightweight phone that moves smoothly in hard-to-reach areas.
