Oilless Self-Lubrication Bronze Graphite Plugged Bushings are high-performance components designed to provide seamless and efficient operation in various industrial applications.

Constructed from bronze, these bushings exhibit excellent strength and durability, making them suitable for high-load and high-speed applications. The bronze material also offers good corrosion resistance, ensuring long-lasting performance even in harsh environments.

The key feature of these bushings is their oilless self-lubrication design, which incorporates graphite plugs. The graphite provides excellent lubrication properties, reducing friction and wear, while eliminating the need for regular lubrication. This significantly reduces maintenance requirements and operational costs.

The precision-fitted design of Oilless Self-Lubrication Bronze Graphite Plugged Bushings ensures accurate alignment and stability, providing smooth rotation and reduced vibration. This also contributes to improved efficiency and reliability of the rotating system.

These bushings are commonly used in machinery, pumps, motors, and other rotating equipment where smooth and efficient operation is crucial. Their self-lubricating properties and robust construction make them a reliable and cost-effective solution for industrial applications.

With 's reputation for quality and performance, these bushings are trusted by many industries worldwide for their long-lasting and dependable operation.

Graphite copper sleeve with high strength copper alloy bronze bearings (cuzn25al5 cuzn24al6fe3mn4) as basic material, according to a certain proportion according to the operating conditions in the working face processing out of the cavity and fill in the solid lubricant, high strength copper alloy provides a high bearing capacity and the solid lubricant can form low friction pair. Under the condition of dry friction, we design a layer of lubrication film on the bearing surface to ensure that the solid lubricant is transferred to the dual parts in a short time and an effective solid lubrication film is formed.

Product features: Can be used for a long time without maintenance; Designed for high static and dynamic loads; It has a very low and stable friction coefficient and no "adhesion" phenomenon. With dust resistance, corrosion resistance, impact resistance, and edge load resistance; The metal substrate has good shock absorption ability. Can be used over a wide temperature range; Suitable for reciprocating, rotating, and swinging.

Viiplus is a professional supplier of self - lubricating bearings in China

Main application fields: high-end mining machinery, engineering machinery, hydropower machinery, automobile, ship, oil and other machine tools.

We are committed to providing high quality copper materials and self-lubricating products to meet the needs and progress of The Times.

Sliding copper bushing -'s maintenance-free plain bearings are made of very hard bronze (base material) and specially placed inserts made of solid grease (graphite).Set the graphite to match the direction of travel.The base material bears the load, and the solid grease ensures the lubrication of the bearing throughout its service life.The graphite composition must be able to lubricate the sliding surface of bronze.As the bearing rotates, the grease film diffuses to brown.This means that there is always a gap between the two sliding surfaces in order for the bronze and graphite to work effectively.Recommended maximum operating temperature: 300°C (bearing manufactured at 1000°C) greater clearance shall be provided to compensate for thermal expansion at operating temperatures above 100°C.Necessary maintenance usually involves checking consumption every six months to two years, depending on usage time and load.It is recommended that the parts be re-lubricated each time they are removed.Do not remove the existing solid grease layer.Continuous lubrication is not required, as the part does not require maintenance if all requirements for the use of bronze with solid grease are complied with.Machining: bronze is easy to process.Basically, there is not much difference between our products and ordinary steel processing.No special tools are required, but remember to use sharp tools, preferably new ones.It is recommended to use grease or carbide tools.As with ordinary steel, the distance of the machine is about 0.3 mm during rough milling.When milling/roughing, use low feed rate and low cutting depth.

Application characteristics

Jdb-1 is a universal basic product, regardless of high pressure, low pressure, high temperature, low temperature, oil lubrication, oil free lubrication or water lubrication.They all apply.The matrix of the product is high-strength brass, which is twice as hard as the general copper cover.Wear resistance increased more than twice.Therefore, the continuous casting machine, rolling mill, conveyor in the metallurgical industry can be used.Also used for plastic injection molding machine locking mechanism, extrusion mechanism.Automatic switch of high voltage, lifting support of construction machinery, and arc door support of water conservancy project.Pulley and drive wheel parts.There are also paper dryer, automobile mold, ship anchor sliding parts and so on.

JDB 1 2 is mainly suitable for low load, high temperature and medium speed applications, such as fireplace door hinges, oven raceway, light industrial machinery, machine tool industry, etc.
The internal material of jdb-3 is the same as that of jdb-2. In addition to the function of jdb-2, it also reflects the functions of saving cost, improving compressive strength and welding and installation of end face and matrix. It is suitable for non-oil lubricating parts in construction machinery, metallurgical machinery and conveying machinery.
Jdb-4 is a typical material - saving product where mechanical properties are not required.It can be used as a substitute material for jdb-2.Can greatly reduce the cost, to meet the use of requirements, such as: mold guide sleeve, injection molding machine mold frame.

Jdb-5 is an enhanced product.It has very high compressive performance, especially suitable for supporting parts of the crane, such as excavator support, winch support, crane support, etc.But because the matrix is steel.So should not be used in water or acid, alkali occasion.
