There are many types of copper sleeves, including machine copper rollers and copper bearings. Oil lubricated bearings are used in various large and heavy machinery and are important components of machinery.
Copper sleeves, also called copper shaft sleeves, are divided into a variety of types, including machine copper rollers, copper bearings, and so on. Used for various light industry, large and heavy machinery, it is an important component of machinery. The product has the traditional tin bronze bearing function. It uses electrolytic copper as the raw material and a variety of trace metal elements. It is sintered at high temperature and processed by air pressure centrifugal casting. High hardness, excellent wear resistance, not easy to cause seizure, good casting performance and cutting performance, good corrosion resistance in the atmosphere and fresh water. In the absence of lubricants and water-based lubricants, it has good sliding and self-lubricating properties, easy cutting, poor casting properties, and good corrosion resistance to dilute sulfuric acid. General-purpose structural parts, simple castings for ships, instruments, etc., such as sleeves, bushings, bearings, sliders, etc.
The material of the copper sleeve is as follows:
ZCuSn10Pb1
High hardness, excellent wear resistance, not easy to cause seizure, good casting performance and cutting performance, good corrosion resistance in the atmosphere and fresh water.
Can be used for wear-resistant parts working under high load (less than 20Mpa) and high sliding speed (8m / s), such as connecting rods, bushings, bearings, gears, worm gears, etc.
ZCuSn10Pb5
Corrosion resistance, especially for dilute sulfuric acid, hydrochloric acid and fatty acids.
Structural materials, corrosion-resistant and acid-resistant accessories, as well as crusher bushings and bushes.
ZCuPb10Sn10
Good lubricating performance, wear resistance and corrosion resistance, suitable for bimetal casting materials.
轴承 Bearings for vehicles, bimetallic bearing pads for internal combustion engines with peak load of 100Mpa, as well as piston pin sleeves, friction plates, etc.
ZCuPb15Sn8
In the absence of lubricants and water-based lubricants, good sliding and self-lubricating properties, easy cutting, poor casting properties, and good corrosion resistance to dilute sulfuric acid.
Bearings with high surface pressure and side pressure can be used to manufacture copper cooling tubes of cold rolling mills, parts with impact resistance up to 50Mpa, bimetallic bushes for internal combustion engines, mainly used for piston pin sleeves with a maximum load of 70Mpa, and acid-resistant accessories .
ZCuZn38Mn2Pb2
It has good mechanical properties and corrosion resistance, good wear resistance and good cutting performance.
Structural parts for general use, simple castings such as sleeves, bushings, bearings, sliders, etc. used in ships and instruments.
