How to choose the right medical device bearing

 

With the development of the domestic medical industry, the requirements for medical device bearings are getting higher and higher, and how to choose a suitable medical device bearing is becoming more and more important. The following are several aspects that need to be paid attention to when choosing medical device bearings:

 

1. Safety characteristics of bearing material;

 

2. The safety characteristics of bearing grease need to meet at least the safety standards for medical use;

 

3. Anti-rust performance of bearing;

 

4. The service life of the bearing.

 

The above points are several key points for choosing medical device bearings, because the medical environment is changeable, and the bearings must meet the medical use standards in many aspects in order to meet the medical environment use.

 

How to choose the right medical device bearing

Generally speaking, most of the medical device bearings are stainless steel bearings, because the advantages of stainless steel bearings are much superior to the characteristics of ordinary bearing steel, at least one point, it has a certain anti-rust function. In addition, most of the domestic manufacturers use medical stainless steel bearings are ordinary grade stainless steel materials, so the service life is not very long, and even easy to damage,CWL BEARING  mainly specializes in stainless steel bearings for medical devices, in the use of safety, life, and material characteristics have reached the international level of requirements, as far as stainless steel bearings are concerned:

 

The bearing rings and rolling elements are made of AISISUS440C stainless steel (domestic code: 9Cr18Mo, 9Cr18) after vacuum quenching and tempering, and the cage and sealing ring are made of AISI304 stainless steel (domestic code: 1Cr18). Compared with ordinary bearing steel, stainless steel bearings have stronger rust and corrosion resistance, and can be used in the environment of -60°C~+200°C when choosing the appropriate lubricant and dust cover. For example, stainless steel S695-ZZ bearings are equipped with dust covers. The S695-2RS is fitted with a contact seal. Bearings with shields or seals on both sides are lubricated for life and require no maintenance. Stainless steel bearings can be widely used in food processing, medical equipment, and pharmaceutical machinery due to their high mechanical strength and large load capacity.

 

Advantages of stainless steel bearings

1. Excellent corrosion resistance: stainless steel bearings are not easy to rust and have strong corrosion resistance.

 

2. Washable: stainless steel bearings can be washed without relubrication.

 

3. Can run in liquid: Due to the materials used, we can run in liquid.

 

4. Slow depletion rate: AISI316 stainless steel, no oil or grease anti-corrosion protection is required. Therefore, if the speed and load are low, lubrication is not necessary.

 

5. Hygiene: Stainless steel is naturally clean and does not corrode.

 

6. High heat resistance: can run at higher temperature ranges from 180°F to 1000°F. (High temperature resistant grease is required).

 

To sum up, the selection of good medical device bearings is indispensable for the development of the medical industry, and the bearings commonly used in medical devices are stainless steel bearings, so the choice of excellent and professional bearing manufacturers is also a necessary condition.
