Centrifugal Casting Alloy Copper Bearing Good Self Lubricating Performance
Product description
The copper bearing is located on the shaft, which plays the role of bearing, also known as sliding bearing. It is a bearing working under sliding friction. The relative shaft is rotating, which generally needs to be assisted by a lubrication system. The sliding bearing is stable, reliable and noiseless. Under the condition of liquid lubrication, the sliding surface is separated by lubricating oil without direct contact, which can greatly reduce the friction loss and surface wear, and the oil film also has certain vibration absorption capacity.
The copper sleeve can work for a long time without oil lubrication or with little oil, and has good self-lubricating performance. Copper sleeve is
more suitable for the condition of heavy load and low speed, with good wear resistance and very low friction coefficient. Copper sleeve is suitable for reciprocating, rotating, swinging and intermittent motion, etc. where oil film is difficult to form. The copper sleeve has corrosion resistance and chemical resistance. Copper sleeve is suitable for - 40 ℃ ~ + 300 ℃, maintenance free, long service life.
Production and processing
Centrifugal casting copper bearing is a technology and method that liquid copper is injected into the high-speed rotating mold to fill the mold and form the casting under the action of centrifugal force. The centrifugal force makes the liquid copper fill the mold and form the free surface of the casting well in the radial direction; the cylindrical inner hole can be obtained without the core; it is helpful to eliminate the gas and inclusions in the liquid copper; it affects the crystallization process of the copper liquid, so as to improve the mechanical properties and physical properties of the casting.

Material selection
The main materials of copper bearing produced by our company are brass, high strength brass, aluminum bronze, tin bronze, zinc base alloy and other non-ferrous metals. Because of the material characteristics of tin bronze, tin bronze is mainly used for product processing.
The brief introduction of tin bronze is as follows: tin bronze: tin bronze is a copper tin alloy with tin as the main added element, and the tin content is generally between 3% - 14%. Tin bronze has good wear resistance and corrosion resistance, which is suitable for gear turbine bearing. Tin bronze has good casting performance, antifriction performance and mechanical properties. It is suitable for manufacturing copper sleeve, worm gear and gear with high elastic limit, high elastic modulus, wear resistance and corrosion resistance. It is suitable for manufacturing all kinds of corrosion-resistant and wear-resistant elastic components.
