What are maintenance-free bearings?

source：未知   time：2024-10-30 11:09nbsp;  click：

Maintenance-free bearings refer to rolling bearings that can work stably for a long time without maintenance from installation to failure. They have excellent performances of maintenance-free, high performance, long life, more environmentally friendly, reliable and durable.
The main features of maintenance-free bearings are: light weight, high strength, self-lubricating and maintenance-free, corrosion resistance, dust resistance, wear resistance, and low friction coefficient. As long as they are used properly, they are generally used until the end of their life.
Maintenance-free bearings greatly reduce the consumption of grease by optimizing the geometry and surface finish of the bearing grooves, redesigning the retainer, combining the use of high-performance bearing steel with a unique heat treatment process, and improving the accuracy of the steel balls.
The optimized sealing structure makes it easier to store grease and precipitate lubricating oil into the grooves, and with the filling of full-life grease, it provides more lasting lubrication for rotation. The improvement and application of multiple processes have achieved a huge improvement in bearing performance and eliminated regular maintenance during the life cycle of the bearing.

Advantages of maintenance-free bearings
1. No need to add oil, long life, can greatly reduce the frequency of bearing replacement and reduce the generation of waste.
2. Adopt special maintenance-free technology, no need to add oil to the bearing for maintenance. The device will not be polluted by continuous oiling, and a clean working environment can be maintained.
3. Compared with standard bearings, maintenance-free and long life can reduce CO2 emissions by 79.1%. Through a longer service life, the environmental load is reduced.
4. Long life can reduce the operating costs of the enterprise. Even if the initial purchase cost is higher than that of standard bearings, the total cost is reduced.
