Maintenance method of oilless bearing

Bearing is a component which can fix and reduce load friction coefficient in the process of mechanical transmission. Its main function is to support the mechanical rotating body to reduce the friction coefficient of mechanical load in the transmission process. According to the different friction properties of moving elements, bearings can be divided into rolling bearings and sliding bearings.

In order to ensure the smooth and reliable operation of most bearings, most of them add lubricating oil for lubrication. The purpose is to reduce the internal friction and wear of bearings, prevent burning and sticking, prolong the fatigue life of bearings, discharge friction heat or heat from outside, and the oil film also has certain vibration absorption capacity. However, one of the biggest disadvantages of adding lubricating oil is that it needs good sealing performance, otherwise it will cause leakage, and some equipment with special requirements do not allow the leakage of lubricating oil, so people use other lubricating materials to replace lubricating oil and invent oilless bearing bushing, which not only has the advantages of bearing with lubricating oil, but also eliminates the environmental pollution caused by leakage.

what is oilless bearing？

Oilless bearing bushing is a new type of bearing which has the characteristics of metal bearing and oil-free lubrication bearing. It is loaded by metal matrix and lubricated by solid lubricating material with special formula. It has the characteristics of high bearing capacity, impact resistance, high temperature resistance and strong self-lubricating ability. It is especially suitable for heavy load, low-speed, reciprocating or swinging occasions which are difficult to lubricate and form oil film, and is not afraid of water erosion and other acid erosion and erosion.

The advantages of oil-free bearings are well known. All machines must use some kind of bearings for smooth operation. Oil free bearing is a new type of bearing which has the characteristics of metal bearing and oil-free lubrication bearing. It is loaded by metal matrix and lubricated by solid lubricating material with special formula. It has the characteristics of high bearing capacity, impact resistance, high temperature resistance and strong self-lubricating ability. It is especially suitable for heavy load, low-speed, reciprocating or swinging occasions which are difficult to lubricate and form oil film, and is not afraid of water erosion and other acid erosion and erosion.

In order to extend the service life of oilless bearing bushing, we need to carry out maintenance on oilless bearings. Then the following manufacturers of oilless bearing will introduce some maintenance methods for oilless bearing.

Maintenance method of oilless bearing

In order to maintain the original function of oilless bearings in good condition as long as possible, maintenance and inspection are necessary to prevent accidents in advance, ensure the reliability of operation, and improve the productivity and economy. The maintenance should be carried out according to the scale before the operation of the machine. The contents include supervising the running state, adding or replacing lubricants, and regular disassembly inspection. As inspection items in operation, whether there is rotation sound, vibration, temperature and lubricant status of oil bearing.

Oilless bearing lubrication

The purpose of lubrication of dynamic elastic oil-free bearing is to reduce the internal friction and friction loss of oil-free bearing and prevent burning and sticking. Its lubrication effect is as follows:

Discharge of friction heat and cooling

The oil can be used to remove the heat generated by friction, or heat from the outside, and cool it. Prevent overheating of oil-free bearing and aging of lubricating oil itself.

Prolong fatigue life

The dynamic and elastic fatigue life of oil-free bearing is prolonged if the dynamic elastic contact surface is well lubricated during rotation. On the contrary, if the oil viscosity is low, the lubricating oil film thickness is not good, it will be shortened.

Reduce friction and wear

It can prevent metal contact and reduce friction and wear in the contact section of ring, moving body and retainer of oil-free bearing.

Others

It also has the effect of preventing foreign matters from invading into the oil-free bearing, or preventing rust and erosion.

The above is all about the maintenance methods of oilless bearings. I hope it will help you. For more information, please pay attention to the manufacturers of oilless bearings.
