Oil free bearings have the characteristics of high load-bearing capacity, impact resistance, high temperature resistance, and strong self-lubricating ability. They are particularly suitable for heavy loads, low speeds, reciprocating or swinging situations that are difficult to lubricate and form oil films. They are also not afraid of water erosion and other acid liquids.
Bearings are components that fix and reduce the friction coefficient of loads in mechanical transmission processes. Its main function is to support mechanical rotating bodies and reduce the friction coefficient of mechanical loads during the transmission process of equipment. According to the different friction properties of the moving components, bearings can be divided into two categories: rolling bearings and sliding bearings.
Most bearings are lubricated with lubricating oil to ensure smooth and reliable operation, with the aim of reducing internal friction and wear, preventing burning and sticking, and extending the fatigue life of the bearings; Discharging frictional heat or heat transmitted from the outside; At the same time, the oil film also has a certain ability to absorb vibrations. However, the biggest drawback of adding lubricating oil is the need for good sealing performance, otherwise leakage may occur. Some equipment with special requirements does not allow lubricating oil leakage, so people used other lubricating materials to replace lubricating oil and invented oil-free bearings, which not only have the advantages of lubricating oil bearings, but also eliminate environmental pollution caused by leakage.
