Bi-Metallic Bearings Applications and Scenarios

Bi-Metallic Bearings are extremely reliable and efficient components used for a wide variety of applications, from automotive and aerospace, to medical and industrial. Featuring a set of two different bearing materials, usually a steel outer ring and a copper inner ring, these bearings are capable of withstanding high temperatures and are corrosion resistant. The superior quality of the Bi-Metallic Bearings makes them ideal for applications that require high levels of precision and performance, such as automotive wheel hub assemblies, machine tools, electric motors, and aerospace components.

Bi-Metallic Bearings are well-suited for a variety of applications since they offer several benefits. These include a high level of precision, improved resistance to wear and tear, a longer service life, outstanding load-bearing capacity, and higher heat tolerance. Additionally, the bearings are produced with a strict adherence to the ISO 16949 certification, ensuring that every product is of the highest quality.

Bi-Metallic Bearings are available in a range of sizes and have a variety of seals, such as a rubber seal, steel shield, and metal plate seal. The bearings are also available with a variety of precision levels, from ABEC-3 to ABEC-7, and the maximum speed of the bearings can vary from 2,000 rpm to 40,000 rpm. The static load rating of the bearings can range from 0.1 KN to 10 KN.

The Bi-Metallic Bearings have a Place of Origin in China and are packaged with either cartons or pallets. The superior quality of the Bi-Metallic Bearings, combined with their extensive range of applications, makes them an ideal choice for many industries.


Bi-Metallic-Bearing-System is a product with multiple customization options. The place of origin of this product is China and it is certified with ISO 16949. Packaging details include cartons and pallets. Lubricant, precision, finish, cage and outer diameter of the product can vary.

Our Bimetal-Bearing is designed for heavy-duty industrial applications and is well-suited for high-temperature and corrosive environments. It is built with two layers of metal- one layer for shock absorption and one layer for strength. The outer diameter of the bearing can be customized according to the customer’s requirements.

We also offer Bi-Metallic-Bearing-Assembly that is designed for high-performance applications and is ideal for high-speed and heavy-load operations. This bearing assembly is constructed with two layers of metal and is available in various finishes, precision, lubricant and cage options.

Packing and Shipping:


Bi Metal Bearings Packaging and Shipping

The packaging for bi metal bearings is typically done using poly bags and cartons. The bearings are padded and secured in the cartons to ensure safe delivery. Depending on the size and weight of the shipment, the cartons are then stacked on pallets for easier handling and shipping. The pallets are then shrink-wrapped for extra protection.

The shipping of bi metal bearings is typically done via air and sea freight, depending on the destination and urgency of the shipment. Delivery times will vary depending on the destination, but typically, orders are delivered to the customer within seven to ten business days.




Q1: What is a bi-metal bearing?

A: A bi-metal bearing is a bearing made of two different metals combined together. It offers the advantages of both metals, such as hardness and corrosion resistance.

Q2: Where are bi-metal bearings made?

A: Bi-metal bearings are made in China and certified by ISO 16949.

Q3: How do bi-metal bearings work?

A: Bi-metal bearings work by using the different properties of the two metals combined together to create a bearing that can handle higher loads, higher speeds, and more wear and tear than a single metal bearing.

Q4: What is the packaging of bi-metal bearings?

A: The packaging of bi-metal bearings is usually cartons or pallets.

Q5: What are the advantages of bi-metal bearings?

A: The advantages of bi-metal bearings include higher load capacity, higher speed capability, better corrosion resistance, and greater wear resistance.
