At our company, we take pride in offering a comprehensive range of cast bronze bearings and slide plates. Our product lineup includes cast bronze sleeve bearings, flange bearings, and customized parts, all designed to cater to your specific needs. These bearings can be equipped with either oil grooves or grease grooves, providing versatile options for lubrication.

When it comes to oil grooves and grease grooves, there are notable distinctions. Grease grooves are generally wider and deeper, enabling them to hold a sufficient amount of grease and facilitating its application. On the other hand, oil grooves tend to have varying widths but are shallower compared to grease grooves. Most oil grooves are used in constant loss or closed oiling systems, ensuring a steady supply of less viscous oil to the grooves. For grease applications, we recommend utilizing double loop grooves and double figure eight groove configurations.

For those seeking maintenance-free solutions, we offer bronze bearings with graphite-filled grooves and graphite plugs. The graphite acts as a dry lubricant, providing continuous lubrication without the need for regular maintenance. The ID groove patterns can be filled with a specialized hardenable graphite paste, while graphite plugs can be securely fitted through the bearing wall using a special epoxy resin binder. Typically, the graphite plugs have a diameter of 7mm and cover approximately 25% of the surface area. They can be strategically placed around specific features of your parts. It’s important to note that graphite bronze parts should operate without the use of oil or grease. Our graphite plug bearings typically exhibit a coefficient of friction ranging from 0.10 to 0.15, depending on various performance factors.

We prioritize delivering high-quality products and services to meet your requirements, contact us now.

What are Bronze Graphite Bushings?

Bronze graphite bushings are cylindrical sleeves made from a bronze alloy that is infused with graphite particles. The graphite acts as a dry lubricant, reducing friction and wear between moving parts. These bushings are designed to withstand heavy loads, high temperatures, and harsh operating conditions.

Composition and Properties

Bronze graphite bushings are typically composed of bronze alloys such as tin bronze or aluminum bronze. The addition of graphite particles enhances their lubricating properties. The bronze matrix provides strength and durability, while the graphite ensures low friction and self-lubrication.

Graphite bushings impregnated To Achieve Self Lubricating

The so-called no oil supply means that there is no need to add oil or less oil. Our research aims to ensure that the graphite bushings impregnated can still perform well under this working condition and prolong its service life as much as possible.

The basic working principle of self-lubricating bearings is that in the initial running stage, the solid lubricant on the graphite bushings impregnated surface forms a transfer film due to mutual friction and coats the opposite abrasive parts to form a solid lubricating film to achieve the purpose of self-lubricating. The direct contact between the workpieces thus protects the abrasive parts and prolongs the service life of the bearing and the workpiece.

Bronze Graphite Sleeve Bushings, Flanged Bushings, Thrust Washers, Radial Bearings

manufacturing bronze alloy, solid bronze bushing

Bronze graphite sleeve bushings, flanged bushings, and thrust washers are types of mechanical components commonly used in various industries for their specific applications. Let’s briefly explain each of them:

Bronze Graphite Sleeve Bushings: These are cylindrical bearings made of bronze infused with graphite. The graphite provides self-lubricating properties, reducing friction and wear between moving parts. Bronze graphite sleeve bushings are often used in applications where frequent lubrication is impractical or where low-maintenance operation is required.

Flanged Bushings: Flanged bushings, also known as flanged bearings or bushings with flanges, have an extended flange at one end. The flange acts as a built-in support or stopper, providing axial guidance and preventing the bushing from moving out of position. Flanged bushings are commonly used in applications where axial movement needs to be limited or where the bushing needs to be securely held in place.

Thrust Washers: Thrust washers are flat, washer-like components used to support axial loads in rotary or linear motion systems. They are often made of bronze, brass, or other low-friction materials. Thrust washers provide a smooth bearing surface for rotating or sliding parts, minimizing friction and wear between them. They are commonly used in applications such as automotive transmissions, hydraulic systems, and industrial machinery.

Radial bearings are a type of rolling-element bearing designed to support radial loads, which are forces acting perpendicular to the shaft’s axis. They are commonly used in rotating machinery and equipment to enable smooth and low-friction motion.

These components play crucial roles in various mechanical systems, providing support, reducing friction, and extending the lifespan of moving parts. Their specific design and material properties make them suitable for different applications and operating conditions.
