1. Product Description

The copper sleeve used in engineering machinery and equipment is a copper alloy wear-resistant material with good wear resistance, corrosion resistance and thermal conductivity. It is widely used in engineering machinery, petrochemical industry, coal and other fields.

1)Types of copper sleeves

Copper sleeves can be divided into dry copper sleeves and oil-immersed copper sleeves according to different use environments. Dry copper sleeves are generally used in environments without lubricating oil, while oil-immersed copper sleeves are used in lubricating oil environments. In addition, according to different manufacturing materials, copper sleeves can be divided into cast copper sleeves and forged copper sleeves. Cast copper sleeves are made by melting copper alloy and making a blank, while forged copper sleeves are made by forging copper alloy and making a blank.

2) Manufacturing process of copper sleeves

The manufacturing process of copper sleeves mainly includes smelting, mold design, pouring, cooling, processing and other links. Among them, smelting is one of the key links in the manufacturing of copper sleeves. The copper alloy material needs to be heated to the melting point, smelted, and then poured and cooled. Processing involves turning, drilling and other operations on the copper sleeve blank to meet the usage requirements.

3) Characteristics of copper sleeves

1. Good wear resistance: Copper alloy materials have good wear resistance and can withstand the wear of high loads and high-speed operations.

2. Corrosion resistance: Copper alloy materials have strong corrosion resistance and can adapt to long-term use in various environments.

3. Good thermal conductivity: Copper alloy materials have good thermal conductivity and can effectively dissipate heat and maintain the stable operation of mechanical equipment.

4. High strength: Copper alloy materials have high strength and can withstand large pressure and torque.

5. Long service life: Because the copper sleeve has good wear resistance, corrosion resistance and thermal conductivity, it has a long service life.

Product characteristics

​Hydraulic special bearing: It is a new type of material designed on the basis of SF-1P and combined with the working principle of oil cylinder and shock absorber. It appears wear-resistant under oil-free conditions. In addition to the advantages of SF-1D, this product is particularly Suitable for occasions with frequent reciproion and large lateral force. Its performance is similar to that of foreign DP4. At present, this product is gradually replacing SF-1P products, and is suitable for automotive and motorcycle shock absorbers and various hydraulic cylinders.
Maximum bearing pressure 140N/mm² Friction coefficient μ 0.04~0.20
Applicable temperature range -195℃~280℃ Maximum allowable PV value (dry) 3.8N/mm²·m/s
Maximum sliding speed 3m/s Maximum allowable PV value (oil) 50N/mm²·m/s
