Special Lubricated Bearings

In order to maximise a bearings life within today’s market of increased speeds and higher temperatures lubrication is defiantly the key but understanding what lubrication does for a bearing is important in order for you to decide what form of lubrication is best.

The main purpose of lubrication for bearings is to prevent contact between the rolling elements, raceways and cage. It is ultimately used to prevent the bearing from suffering from corrosion and wear. It has many uses when it comes to prolonging the life of the bearing and helping it to work at its best. Also it has additional features and functions such as the sealing and cooling of the bearing.

There are many ways in which a bearing may be lubricated in order for it to do its job more effectively. In some cases the bearing may be lubricated with grease or oil. These represent two of the most commonly used traditional methods of lubrication. However in many other cases you may use a special lubricated bearing. These special lubricated bearings are generally made of bronze powder by uniaxial pressing. The microscopic cavities following pressing (porosities) are filled with oil, which comes to the surface when the bearing is used.

These special lubricated bearings are generally used in low pressure, high frequency and small amplitude applications as well as within methods of operating and constructing. The choice however of which lubricated bearing you decide to use depends primarily on the temperature range, operating speeds and loading conditions of the bearings that are concerned.

The lubrication of bearings has an important effect on the function of the bearing. This is why it is important you choose the right form of lubricated bearing as it has an effect on the life span of the bearing. So what exactly are the advantages of lubricated bearings?

• They reduce the friction and wear by lubricating every part of the bearing.
• It takes away the heat that is generated inside the bearing as a result of friction or for many other reasons.
• It forms an oil film within the rolling contact surface in order to elongate the bearing life.
• It prevents the bearing from rusting as well as suffering dust contamination.

It has been stated that all lubricants must be changed from time to time due to the fact that their properties deteriorate as a result of aging as well as the contamination. If you are currently in this position then have you thought about investing in special lubricated bearings? These are generally self lubricated bearing, which are made from bronze and have built in lubrication that kicks in when it is needed. These forms of lubricated bearings have a tendency to last longer than other forms of bearings and could give you the optimum performance that you have been looking for.

These special lubricated bearings will not only solve the problems with oiling operations but they will also extend the service life of machines. Even under severe conditions, special lubricated bearings have superior durability, quality, stability and performance within various applications. These bearings offer advantages such as compact design, longer service life, manpower and environmental saving as well as non environmental pollution. So next time you are after lubricated bearing look no further than special lubricated bearings.
