Maintenance-Free bearings, as the name implies, refer to bearings that do not require frequent maintenance, and can be used for long-term stable operation from maintenance to failure. Maintenance-free bearings are mainly divided into open type and sealed type. Open-type maintenance-free bearings need to be matched with a maintenance-free design seal structure to achieve maintenance-free technical requirements and sealed maintenance-free bearings can be used directly.

Maintenance-free bearings are mainly reduced by optimizing the geometry and surface finish of the bearing channel, redesigning the retainer, the use of high-performance bearing steel and a unique heat treatment process, and improving the accuracy of the steel ball. The consumption of grease;

The optimized sealing structure is easier to store grease and lubricating oil to the channel. With the full life grease filling, it provides more durable lubrication for rotation. These process improvements and applications can achieve a huge increase in bearing performance, eliminating the need for regular maintenance during the bearing life cycle.

Common maintenance-free bearings currently on the market usually refer to sealed maintenance-free bearings.

These bearings have many advantages. First, they do not need to be refueled regularly. Their life is usually longer, which can greatly reduce the frequency of bearing replacement and help reduce waste generation.

Second, these bearings use a special maintenance-free technology. When they are used, they do not need to be regularly refueled and maintained. The device will not cause pollution due to continuous refueling, and can maintain a clean working environment.

Third, compared with standard bearings, maintenance-free bearings have a longer service life and produce less carbon dioxide emissions than ordinary bearings. The use of such maintenance-free bearings can reduce the load on the environment and reduce Emission of polluting gas, protect the environment and save resources.

In addition, the long service life of 3102-2201025 Russian universal joint cross also means that the use of them can reduce the operating costs of enterprises. Although the purchase price of these maintenance-free bearings is relatively high, compared with the benefits brought by the use process, in fact Overall, the cost is saved.
