Powder Metallurgy Oil Bearing Copper Sleeve | Pure Copper Shaft Sleeve M3-M60

This powder metallurgy oil bearing copper sleeve is a self-lubricating component designed for smooth, quiet operation in rotating machinery. Made from a copper-base alloy, it provides reliable support for shafts while reducing friction and wear.

The pure copper shaft sleeve is a standard size component that fits a range of applications from M3 to M60. It works by holding a small amount of oil within its porous structure, which is released gradually during operation to keep the shaft lubricated. This design reduces the need for frequent maintenance and helps extend the life of both the sleeve and the shaft.

This bearing sleeve is built to handle moderate speeds and loads. The copper material offers good thermal conductivity, which helps dissipate heat away from the shaft. It is a practical choice for many industrial and mechanical applications where reliable performance is needed.

We also support custom sizes for this bearing copper sleeve. If you need a specific dimension not listed, please contact our customer service team to discuss your requirements.

Key Features and Benefits

- Self-lubricating porous structure that releases oil during operation for reduced friction

• Copper-base alloy material that provides good thermal conductivity and heat dissipation

• Standard sizing from M3 to M60 that fits common shaft dimensions

• Customizable design that lets you order specific sizes for unique applications

• Durable construction that supports moderate speeds and loads for long service life

• Low maintenance design that reduces the need for frequent lubrication

Who Is This For

- Mechanics and technicians who need replacement bearings for industrial machinery

• Hobbyists and DIY builders working on small engines, pumps, or power tools

• Maintenance teams looking for cost-effective, standard-size shaft sleeves

• Engineers who require custom-sized copper bearings for prototype or production equipment

Usage Scenario

A small workshop owner was restoring an old lathe. The original shaft sleeves were worn out, causing vibration and noise during operation. After replacing them with this powder metallurgy copper sleeve, the lathe ran smoothly and quietly. The self-lubricating feature meant the owner did not have to stop work to oil the part every hour, saving time and effort.

Micro Comparison

Compared to standard steel bushings, this copper sleeve offers built-in lubrication that reduces the need for external oiling. While steel bushings are stronger, they often require more maintenance. This copper option is better suited for applications where moderate loads and low maintenance are more important than extreme strength.

Questions and Answers

Question: What does powder metallurgy mean for this sleeve?

Answer: It means the sleeve is made by pressing and sintering copper powder into a solid shape. This creates a porous structure that can hold oil for self-lubrication.

Question: Can I use this sleeve in a high-speed motor?

Answer: This sleeve is designed for moderate speeds and loads. For very high-speed applications, you may need a different bearing type. Check your motor's specifications to be sure.

Question: How do I install this copper sleeve?

Answer: You press it into a housing bore that matches the sleeve's outer diameter. Ensure the bore is clean and the sleeve is aligned before pressing. Use a press or a mallet with a soft face.

Question: Does this sleeve come pre-lubricated?

Answer: Yes, the sleeve is impregnated with oil during manufacturing. It is ready to use right out of the package.

Question: Can I order a size that is not listed in the standard range?

Answer: Yes, we support custom sizes. Contact our customer service team with your specific dimensions, and we can help you place a custom order.
