Oil-free Bearing
May 18, 2018

Bearings are components that fix and reduce the friction coefficient of the load during mechanical transmission. Its main function is to support the mechanical rotating body to reduce the mechanical load friction coefficient of the equipment during the transmission process. According to the different friction properties of the moving elements, the bearings can be divided into two types of rolling bearings and sliding bearings.


In order to ensure the smooth and reliable operation of bearings, most bearings are mostly lubricated to reduce the internal friction and wear of the bearings, prevent sticking: prolong the fatigue life of the bearings, and discharge frictional heat or heat from the outside. At the same time the oil film also has a certain ability to absorb vibration. However, one of the biggest drawbacks of adding lubricating oil is the need for good sealing performance, otherwise it will produce leakage, and some special requirements equipment does not allow the leakage of lubricating oil, so people use other lubricating materials to replace the lubricating oil, invented Oil-free bearings make them not only have the advantages of bearing with lubricants, but also eliminate environmental pollution caused by leakage.
