Durability of release bearings

1. Design features: The design of a release bearing allows the inner and outer rings to separate when necessary, a design that makes it more flexible and adaptable in certain applications. However, this may also mean that the separation mechanism may be challenged under certain extreme conditions of use, thus affecting durability.

2. Material quality: The durability of separation bearings is largely dependent on the quality of the materials used in their manufacture. High-quality materials provide better wear resistance, fatigue resistance and corrosion resistance, thereby extending the life of the bearing.

3. Use conditions: the durability of release bearings is also affected by the use conditions, including load size, speed, temperature, lubrication conditions. In good use conditions, the release bearing can show a long service life.

Durability of plain bearings

1. Working characteristics: sliding bearing works under sliding friction, its durability mainly depends on the material of sliding surface, lubrication condition and the matching accuracy between journal and shaft tile. Under liquid lubrication condition, the sliding surface is separated by lubricant without direct contact, which can greatly reduce the friction loss and surface wear, so as to improve the durability.

2. Material selection: the material of the sliding bearing is crucial to its durability. Commonly used materials for plain bearings include bearing alloys (pasteurized or white alloys), wear-resistant cast iron, copper-based and aluminum-based alloys, and so on. These materials usually have the characteristics of high strength, wear-resistant, corrosion-resistant, etc., and can maintain stable performance in the harsh working environment.

3. Lubrication and maintenance: the lubrication condition of the plain bearing has a direct impact on its durability. Proper lubrication can reduce friction and wear, and prolong the service life of bearings. In addition, regular maintenance and inspection are also important measures to ensure the durability of plain bearings.

Comprehensive Comparison

DESIGN ADAPTABILITY: Split bearings offer a higher degree of adaptability in situations where the inner and outer rings need to be separated, but this can also present certain durability challenges. Sliding bearings, on the other hand, are more focused on providing stable support and lubrication under sliding friction.

MATERIALS AND QUALITY: The durability of both split and plain bearings is highly dependent on the quality of the materials used. High quality materials provide better wear resistance, fatigue resistance and corrosion resistance.

Conditions of use and maintenance: Good conditions of use and regular maintenance are essential to improve the durability of bearings. Whether it is a separating bearing or a plain bearing, its durability will be seriously affected under poor use conditions or lack of maintenance.

In summary, it is not possible to simply assert which is more durable, the release bearing or the plain bearing. In actual application, the appropriate type of bearing should be selected according to the specific use scenarios and needs, and corresponding measures should be taken to ensure its durability. 

For example, in the need for frequent separation of the inner and outer rings of the occasion, you can choose release bearings; while in the need for stable support and lubrication of the occasion, you can choose sliding bearings. At the same time, no matter which bearing type is selected, attention should be paid to the influence of factors such as material quality, use conditions and maintenance status.
