Solid Lubricant Bearings: These bearings use graphite-based solid lubricants that are injected into clean bearings, either ball or roller, then thermally cured and hardened. The graphite solid lubrication moves in conjunction with the cage and balls or rollers and deposits a thin film that prevents metal to metal contact, thus minimizing the coefficient of friction within the bearing

Bearings are an essential component in many industrial and structural applications, providing support and reducing friction between two surfaces that are in contact with each other. Bearings can be found in everything from large industrial machinery to small electronic devices. One of the most common types of bearings is bronze bearings, which are known for their durability, strength, and resistance to wear and tear.

Solid lubricated bearings are used in a wide range of industrial and structural applications for moderate to heavy loads. Solid lubricated bearings are permanently lubricated with graphite solid lubricant compounded and compressed into grooves or circular recesses and are available in a variety of bronze alloys.

CONSTRUCTION

The key to the solid lubricate bearing’s superior performance is its unique structure, composition, and method of manufacture. Solid lubricate bearings are comprised of a bronze substrate and a bronze-lubricant inner structure.

The bronze substrate provides a high load-carrying capacity with excellent dimensional and structural rigidity. The bronze-lubricant inner structure supplies a permanent reservoir of lubricant for continuous restoration of the low friction-bearing surface.

Cast Bronze Alloys， Solid lubricated bearing material.

Bearings with Solid Grease: These bearings come in two types: the spot-pack type, where solid grease is injected into the retainer, and the full-pack type, where all empty space around the rolling elements is filled with solid grease. The solid grease is essentially composed of lubricating grease and has the same viscosity as ordinary grease at normal temperature. However, due to a special heat treatment process, this grease solidifies, retaining a large proportion of the lubricant in it. This helps to extend the bearing life.

Cast bronze alloys have been used for centuries in a wide range of bearing applications. No other bearing material can match their versatility. By alloying copper with other elements, the properties of bronze can be altered to suit the requirements of most applications. The selection of a bronze alloy for a particular application is determined by the physical, mechanical, and metallurgical properties required.

The supporting solid bronze bearing metal shall be high-strength manganese bronze, Copper Alloy UNS No. C86300, manufactured in strict accordance with ASTM B22 Alloy C86300, ASTM B271-C86300, ASTM B505-C86300 or ASTM B584-C86300.

A variety of bronze alloys are available for industrial and structural applications. Aluminum bronze and manganese bronze are often preferred for high-load applications, especially where toughness and vibration resistance are required. For high-temperature applications, heat-resistant materials are available.

Solid lubricated bearing alloys are manufactured in strict accordance with ASTM and ISO material specifications. Centrifugal, continuous, sand, and forged castings are available depending on the size and shape required. Physical and chemical test reports are available upon request.

Bronze bearings are widely used in industrial and structural applications for loads up to 8,000 psi and operating temperatures between -350°F to 2000°F. They are commonly used in heavy-duty applications such as construction equipment, mining machinery, and oil and gas drilling rigs. Bronze bearings are also used in a variety of other applications, including transportation equipment, marine applications, and aerospace equipment.

Bronze bearings are available in a variety of alloys, including phosphor bronze, aluminum bronze, and manganese bronze. Each alloy has its unique properties, and the choice of alloy depends on the specific application requirements. For example, phosphor bronze is often used in marine applications because it is resistant to corrosion, while aluminum bronze is used in high-temperature applications because it has excellent heat resistance.

One of the key features of bronze bearings is that they are permanently embedded with solid graphite lubricants contained in trepanned or circular recesses. This means that they require no external lubrication, making them low maintenance and ideal for applications where lubrication is difficult or impossible. The graphite lubricants provide a self-lubricating surface that reduces friction between the two surfaces, thereby reducing wear and tear.

Radial bearing plates have a curved radial surface and a flat surface. Either or both surfaces can be lubricated. The radial surface is mounted with a matching curved mating plate and is designed to allow deflection and rotation. The flat surface will accommodate linear expansion and contraction. Spherical bearing plates have lubricated concave or convex spherical surfaces that allow rotation in any direction. Spherical bearing plates can accommodate sliding, rotation and severe angular deflection. Matching spherical assemblies, base plates, backing plates and anchors are also available.

The black dots as the feature of the premium self-lubricating bearing material;

The black dots are a self-lubricating solid bronze lubricate material a better alternative for that dimension. So this type of bearing’s superior performance is its unique structure, composition, and method of manufacture. The black dots are solid lubricant material and are suitable for most industrial and structural applications.

Bearings are comprised of a bronze substrate and black dots lubricants consisting of solid graphite plugs inner structure.

The natural lubricity and high concentration of the graphite black dots result in a low coefficient of friction and provide excellent wear and chemical resistance.

The bronze substrate provides a high load-carrying capacity with excellent dimensional and structural rigidity. The black dots lubricant inner structure supplies a permanent reservoir of lubricant for continuous restoration of the low friction bearing surface.

This type of bearing is lubricated with black dots graphite solid lubricants. it is finished with black dots which are lubricated.

Metallic bearings with embedded solid lubricants are a type of plain bearings designed to provide self-lubricating functions, allowing for extended lifespan, maintenance-free operations, and use in challenging conditions such as high temperatures or underwater environments.

Embedded Solid Lubricants: These are substances integrated into the bearing material, which possess inherently low friction characteristics. They provide lubrication throughout the lifespan of the bearing, eliminating the need for additional external lubricants.

Metallic Bearings: These are bearings made of metal, commonly bronze, brass, or steel. They are robust and durable, capable of handling high load and speed conditions.

metallic bearings with embedded solid lubricants offer a reliable, efficient solution for a wide range of applications, contributing to improved performance and reduced maintenance needs.

Bearings are often used where oil and grease lubrication is not feasible. However, special operating conditions may exist that require the use of supplemental lubricants. In such cases, bronze bearings can be supplied with one of several groove patterns to suit most types of loads, movements and lubrication requirements. Typical patterns include straight grooves, round grooves, figure-of-eight grooves and oval grooves. Grooves can be specified in any width and depth and can protrude from one or both ends. Sealing and sealing grooves can also be added for applications where foreign debris can enter.

Cylindrical Bushings: These are simple cylindrical bearings that are used in a variety of applications. They’re typically used where rotation is required between two parts.

Flanged Bushings: These are similar to cylindrical bushings but have a flange at one end. The flange provides a surface for axial load support.

Thrust Washers: These are a type of bearing that supports axial loads and helps prevent movement along the axis of a shaft.

Thrust Plate: Similar to a thrust washer, a thrust plate is used to support axial loads. The difference usually lies in the size, material, and specific application.

Bar for Machining: This is a piece of raw material, typically metal, that is designed to be shaped and finished using a machining process.

Plate for Machining: Similar to the bar for machining, a plate for machining is a flat, usually rectangular piece of raw material intended for machining.
