What Is A Bronze Slide Bearing

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.

Understanding the Function of Bronze Slide Bearings
The functionality of bronze slide bearings hinges on the principle of hydrodynamic lubrication. As these bearings experience motion, a thin layer of lubricant forms between the contacting surfaces. This crucial lubricant film prevents direct metal-to-metal contact, effectively reducing friction and minimizing wear. Consequently, bronze slide bearings deliver outstanding and long-lasting performance, making them a dependable choice.

Bronze slide bearings have undoubtedly established themselves as reliable workhorses across diverse industries. Their ability to handle a wide range of operating conditions, coupled with their excellent load-carrying capacity and self-lubricating properties, makes them a preferred choice for numerous applications. Whether in the automotive sector, industrial machinery, aerospace, construction, mining, or marine applications, bronze slide bearings continue to facilitate smooth movements and contribute to the overall efficiency and reliability of machines and equipment.

Bronze Slide Bearing Type

Bronze slide bearings come in various forms, with the two most common variants being sintered bronze sliding bearings and self-lubricating bronze sliding bearings.

Sintered Bronze Sliding Bearings:
Sintered bronze bearings are manufactured through a process called powder metallurgy. Fine bronze powder is compacted under high pressure and then heated to a controlled temperature to bond the particles together. The resulting structure is porous, providing an effective lubrication reservoir for the bearing. This self-lubricating property makes sintered bronze slide bearings ideal for applications where external lubrication is challenging or impossible. They are often utilized in dry or low-lubrication scenarios, reducing maintenance requirements and extending the bearing’s service life.

Self-Lubricating Bronze Sliding Bearings:
Self-lubricating bronze slide bearings are impregnated with lubricants, such as graphite or PTFE (polytetrafluoroethylene), during the manufacturing process. These pre-loaded lubricants offer continuous lubrication to the sliding surfaces, minimizing friction and wear. Self-lubricating bronze slide bearings are commonly employed in applications where frequent re-lubrication is impractical or poses operational challenges. These bearings are well-suited for situations involving high loads, slow movements, or extreme temperature variations.

Rolling Bearings VS Slide Bearing

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.

Bronze Bushing Material

Material Requirements For Slide Bearings

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.
