Flange copper bushing selection principles are mainly the following points:

First, according to the working conditions selection

Load size:

If the working load is large, the material with high strength should be selected, such as tin bronze or aluminum bronze flange copper bushing. These materials can withstand high pressure and impact, to ensure that the copper bushing will not be deformed or damaged under heavy load conditions.

For light load occasions, you can consider using brass flange copper bushing to reduce the cost.

High and low speed:

In the case of high-speed operation, you need to consider the coefficient of friction and heat resistance of the copper bushing. A low coefficient of friction copper bushing can reduce energy loss and heat generation, and improve the efficiency and stability of the equipment.

For example, self-lubricating flange bushings typically have a low coefficient of friction and are suitable for high-speed operation. At the same time, it is important to ensure that the copper bushing does not generate excessive heat at high speeds, so as not to affect the normal operation of the equipment.

Working temperature:

If the working environment temperature is high, you should choose the copper bushing material with good heat resistance. For example, aluminum bronze can still maintain good strength and hardness at high temperatures, suitable for high temperature working environment.

In low-temperature environments, we should consider the toughness and impact resistance of the copper bushing, to avoid damage to the copper bushing due to low-temperature embrittlement.

Environmental corrosivity:

If there are corrosive media in the working environment, such as acid, alkali, salt, etc., should choose the copper bushing material with good corrosion resistance. For example, tin bronze and aluminum bronze have good corrosion resistance and can be used for a long time in a corrosive environment.

In addition, you can also consider the surface treatment of copper bushings, such as nickel-plated, chrome-plated, etc., in order to improve its corrosion resistance.

Second, according to the installation mode selection

Integral flange copper bushing:

Integral flange copper bushing installation is simple, high reliability, suitable for limited space, the installation of high precision requirements of the occasion.

Its flange and copper sleeve body molded in one piece, high strength, able to withstand large axial and radial loads.

Split flange copper bushing:

Split flange copper sleeve consists of copper sleeve body and independent flange, easy to install and dismantle, suitable for large equipment or maintenance inconvenient occasions.

According to different working conditions and requirements, different materials and sizes of flanges and copper bushings can be selected for combination, which improves the flexibility of use.

Third, according to the lubrication mode selection

Oil lubrication flange copper bushing:

Oil lubrication flange copper sleeve is suitable for high-speed, high load working conditions, can effectively reduce the coefficient of friction, reduce wear and improve the service life of the copper bushing.

Regular oiling and maintenance of the copper bushing is required to ensure good lubrication. When selecting oil lubrication flange copper bushing, it is necessary to consider the type of lubricant, viscosity and filling method and other factors.

Self-lubricating flange copper bushing:

Self-lubricating flange copper bushings contain solid lubricants such as graphite and molybdenum disulfide. During the working process, the solid lubricant will be gradually released to form a lubrication film, realizing self-lubrication.

Self-lubricating flange copper bushings do not need additional lubrication devices, easy to use, suitable for some occasions that can not be refueled or refueling inconvenience. But its bearing capacity is relatively low, suitable for low load working conditions.

Fourth, according to the cost and performance requirements for selection

Cost factors:

In the selection, consider the balance between the cost and performance of copper bushings. Different materials, structures and lubrication methods of flange copper sleeve price differences.

Brass flanged bronze bushings are relatively low cost, but may not perform as well as tin bronze or aluminum bronze bushings. Under the premise of meeting the work requirements, you can choose a lower-cost copper bushing to reduce the manufacturing cost of the equipment.

Performance requirements:

If the performance requirements of the equipment are high, such as precision, reliability, life, etc., flange copper bushings with good quality and stable performance should be selected.

You can refer to the copper bushing manufacturer, brand and user evaluation and other factors to choose the supplier with good reputation and reliable product quality.
