Application of stainless steel bearings in medical equipment industry

1. Stainless steel bearings are of great significance in medical devices

China's medical industry has developed rapidly in recent years, and the corresponding requirements for medical equipment have become higher and higher. In particular, there are strict regulations on the bearings required for equipment. How to choose suitable bearings is very important. Generally speaking, most medical device bearings are stainless steel bearings. The meaning of choosing stainless steel bearings is very simple, that is, in order to better meet the usage regulations of some equipment, have a certain understanding and mastery of the required bearing mechanical equipment performance, and then understand The technical characteristics of stainless steel bearings themselves have stronger multi-faceted applications.

2. How to choose stainless steel bearings for medical equipment

Stainless steel bearings in medical equipment bear important functions in the overall operation, so how to choose suitable stainless steel bearings?

Because the medical environment is changeable, and in order to comply with the use of the medical environment, the bearings must also meet the medical use standards in many aspects. Here are some key points for selecting medical devices:

1. Safety characteristics of bearing materials;

2. The safety characteristics of bearing grease must at least comply with safety standards for medical use;

3. Anti-rust performance of bearings;

4. Bearing service life.

3. Solutions for stainless steel bearings in medical devices

Medical equipment such as gamma knives, CT machines, X-ray machines, etc., the supporting bearings related to them have the following characteristics due to the high precision and accuracy requirements of the equipment: large bearing dimensions, thin walls, long bearing life Long, high rotation accuracy (P5 level or above), low vibration noise, small starting friction torque, large number of mounting holes and high precision, it is a special bearing with high technical content and high added value.

Among them, products developed for CT scanners include high-precision large-scale thin-walled bearings for E-CT machines, bearings for high-precision and high-performance CT machine scan frames, and SGS source device bearings for super gamma knives. And bearings for X-ray machines, etc.

1. The bearing adopts a four-point contact ball structure, and its main technical parameters are:

2. Main technical indicators:

(1) The outer dimensions and tolerances of each type of bearings meet the requirements of users;

(2) The rotation accuracy reaches P5 level or above, reaching the advanced level of similar foreign products;

(3) The bearing clearance meets the requirements;

(4) The operation is flexible and the noise meets user requirements;

(5) The service life exceeds the 200X106 revolutions required by the user;

(6) The accuracy of the mounting holes meets user requirements.

When selecting bearings for medical devices, the key is to pay attention to the changing needs of the medical environment. At the same time, its operating accuracy is also very important.
