Maintenance-free bearings are special rolling bearings designed to work stably for a long time without regular maintenance. This kind of bearing adopts special maintenance-free technology, so that there is no need to refuel the bearing during use, thereby avoiding pollution caused by continuous refueling and maintaining a clean working environment.
Maintenance-free bearings have the outstanding properties of maintenance-free, high performance, long life, more environmentally friendly, reliable and durable, which can significantly reduce the frequency of bearing replacement and reduce the generation of waste. The sealing structure of this kind of bearing has been optimized to facilitate the storage of grease and the precipitation of lubricating oil into the channel. Together with the filling of full-life grease, it provides longer-lasting lubrication for rotation.
Maintenance-free bearings are mainly classified into two types: open type and sealed type. Open maintenance-free bearings need to be matched with the sealing structure of Merck's maintenance-free design to meet maintenance-free technical requirements; sealed maintenance-free bearings can be used directly.
The sealing structure of maintenance-free bearings has the following characteristics:
1. The sealing structure adopts multi-lip technology, which can prevent external dust and mud from entering the inside of the bearing.
2. An oil guide groove is used inside the bearing so that the oil does not leak from the outside, thus forming an internal circulation inside the bearing.
This sealing structure can ensure that the oil inside the bearing is always in an internal circulation state, thus ensuring the long life and reliability of the bearing.
The advantages of maintenance-free bearings are mainly reflected in the following aspects:
1. Reduce maintenance costs: Maintenance-free bearings do not require periodic lubrication and maintenance, reducing labor and material costs. At the same time, since frequent replacement of bearings is not required, related costs are also reduced.
2. Increase equipment reliability: Maintenance-free bearings reduce lubrication and maintenance operations, which can reduce the possibility of bearing failure, thereby improving equipment reliability.
3. Increase service life: Maintenance-free bearings have a longer service life, which can reduce the frequency and cost of bearing replacement. This not only reduces downtime and production losses, but also reduces waste generation.
4. Environmental protection and safety: Since no lubrication is required, maintenance-free bearings reduce the pollution of the lubricant to the environment and the possible harm to workers. This is in line with the concepts of environmental protection and safe production.
5. High load capacity: Maintenance-free bearings can withstand higher loads, making the machine's operation more stable and safer.
6. Strong durability: Maintenance-free bearings have a long life, reduce the frequency of downtime and replacement, reduce production costs, and improve production efficiency.
7. Anti-corrosion: Maintenance-free bearings are made of special materials, which have strong corrosion resistance and can operate normally in harsh environments.
8. Self-lubricating: Maintenance-free bearings have self-lubricating properties, which can reduce dependence on external lubricants and improve the working efficiency and service life of the bearings.
9. Good sealing: Maintenance-free bearings adopt advanced sealing technology, which can effectively prevent external impurities and moisture from entering the inside of the bearing and keep the bearing clean and stable.
10. Low friction coefficient: Maintenance-free bearings have a low friction coefficient, which can reduce bearing friction and wear and improve bearing efficiency and accuracy.
Maintenance-free bearings have the advantages of high performance, high reliability, long life and low maintenance costs, and are suitable for various mechanical equipment that require high precision, high stability and long life operation.
