Bronze slide bearings work under sliding friction. It has many advantages, such as smooth, reliable, and noiseless work. Under the condition of liquid lubrication, the sliding surfaces are separated by the lubricant without direct contact, thus reducing friction and surface wear, and the oil film has a certain ability to absorb vibration. However, the frictional resistance at start-up is relatively high. It is also possible to inlay graphite solid lubricant on the premise of bronze base material to achieve self-lubricating working conditions. The application of our bronze sliding bearings is generally at low speeds and under heavy load conditions, or in operating areas where maintenance and lubrication are difficult.

Bronze sliding bearings play an integral role in many industries and applications. We probably encounter equipment and applications that use bearings more often than we realize. There are many benefits that bronze slide bearing as a mechanical accessory, and we would like to share the following with you.

• Exemplary corrosion resistance.
• Ability to operate reliably at high temperatures.
• Excellent resistance to friction and wear.
• Easy to work with, especially compared to steel types.
• They can be brazed and welded.
• Bronze slide bearings are still frequently used in ship propellers, underwater bearings, and small electric motors and are also very frequently used in agricultural machinery and construction equipment and applications.

Rolling bearings are bearings in which the friction between the mechanically running shaft and the shaft seat is rolling friction, while plain bearings still operate under sliding friction.

Different Structure

The rolling bearing has a clear structure, and the evenly distributed rolling elements can effectively reduce friction. Therefore, the mechanical start-up is very fast and good, and the maintenance is relatively simple and convenient. In addition, it is more suitable for medium-speed operation. At high speeds, the noise is relatively high, and the service life is shorter. In addition, the rolling bearing vibrates a lot during operation. In comparison, the plain bearing runs smoothly and noiselessly, but the resistance during start-up is relatively large.

The friction force of the rolling bearing is related to the manufacturing process, while the friction of the sliding bearing is related to the manufacturing material.

Not all slide bearings are created equal, so it is important to choose the right bearing material for the job. Factors that influence the final decision include mechanical properties, the cost of processing the material, and of course the physical properties of the material. Similar to C93200 (SAE 660), It has high-quality smooth machine finish stock for general utility bearings and bushings and which are highly resistant to impact, wear, and corrosion.

The requirements for sliding bearing materials are as follows.

• Sufficient tensile strength, fatigue strength, and impact capacity.
•  Good friction reduction, wear resistance, and anti-adhesive properties.
•  Good compliance, embeddedness, and penetration.
•  Good corrosion resistance, thermochemical properties (heat transfer and thermal expansion), and anti-slip properties (ability to adsorb oil)
•  Good malleability. Ability to accommodate shaft bending deformation and other geometric errors.
•  Good manufacturability and economy, etc.

Industrial Machines

Bronze slide bearings are commonly found in various industrial machines, such as pumps, compressors, and hydraulic systems, due to their high load-carrying capacity and self-lubricating properties.

Automotive & Aerospace

In the automotive and aerospace industries, bronze slide bearings are used in engine components, transmission systems, and landing gear assemblies, among other applications.

Marine Engineering

Thanks to their corrosion resistance, bronze slide bearings are widely used in marine applications, such as shipbuilding and offshore drilling equipment.
