Journal Bearings

Cast bronze sleeve bearings are an incredibly simple but highly effective component containing a bearing surface and a mating component. Its role is to guarantee linear or rotational movement between two parts. Cast bronze sleeve bearings have low coefficient of friction, have good sliding property, reduces heat generation, provides substantial wear resistance, and have thinner wall section that requires less space to be housed.

Cast bronze sleeve bearings are intended for both radial and oscillating movement and are suitable for low rotating speeds. These bushings are resistant to corrosive environment, shock loads and vibrations. These bushings are insensitive to dirty environments, can operate with lower quality shaft surface finish and provided with oil holes and grooves to retain lubricants.

Lubrication in these cast bronze sleeve bearings are by hydrodynamic mode, boundary lubrication mode and mixed film mode and are grease and oil lubricated.

Cast bronze sleeve bearings are easy to install, lightweight, and cater to a host of applications like mining equipment, construction equipment, marine equipment, transport equipment and paper making machinery.

Cast bronze sleeve bearings are cast in copper alloys, as they offer the broadest range of applicability. These bearings are centrifugally / continuous / sand cast in cylindrical and flanged cylindrical shapes and machined to precision tolerances. They are low cost and virtually maintenance-free, and as such used in many diverse applications.

Graphite Plugged Bronze Bearings /Graphite Impregnated Bronze Bushings / Oilless Bronze Bushings
Graphite impregnated bronze bushings are also known as graphite plugged bronze bearings or oilless bronze bushings. Graphite impregnated bronze bushings are great for applications where maintenance is difficult and where normal grease and oil based lubricants can burn off due to high temperatures. Bronze body provides the necessary strength to the bearing and graphite plugs acts as reservoir of lubricants. Graphite film from the graphite plug is transferred onto the shaft as it rotates and acts as lubricant even under high loads and low speeds. The cast bronze base material gives stronger bearing ability when compared to self lubricating leaded bronze bushings. The applications for these oilless bronze bushings include construction equipment, transportation machinery, mining equipment etc.

Graphite impregnated bronze bushings are machined out of cast bronze and plugged with graphite plugs. These bearings are available in cylindrical, flanged cylindrical shapes and flat wear plates and machined to precision tolerances.

Bronze & Iron Based Sintered Bearings / Oil Impregnated Bronze Bearings equivalent to "Oilite" Bushings

Sintered bushings are maintenance free journal bearings. These bearings are based on powdered metal technology and consist of porous matrix which are impregnated with lubricating oil. These bearings are also known as oil impregnated bearings and is equivalent to oilite bushings. The lubricating oil contained in the pores in the bearing is circulated and plays the role of lubricant in the bearing system during operation. Sintered bearings have very high sliding velocity making them suitable for rotating applications like machine tools, household equipment, electrical equipment, automobiles and printing machinery.

Sintered bearings are made by compressing metal powders in suitable moulds to give form and structure to the bearings. The formed bearings are then heated to just below the melting point for fusion bonding to give strength to the bearings. The bearings are shaped and sized to the required dimensions, producing precision bearings. The interconnected or open porosity in the bearings is then filled to the required volume with lubricating oil, either by an extended soaking in hot oil or preferably by a vacuum impregnation operation. This process produces precision oil impregnated bearings having light weight, good strength, and accuracy.

Sintered Bushings are manufactured in bronze and iron material, forming sintered bronze bushings and sintered iron bushings respectively. Sintered bushings are made in various sizes in cylindrical, flanged cylindrical, spherical, thrust washer and special shapes. These bearings are economical, suitable for high production rates and can be manufactured to precision tolerances.

Metalcomp specializes in the manufacture and export of customized sintered bronze bushings and sintered iron bushings for a diverse range of sizes and applications. We manufacture sintered bearings as per client’s drawings and specifications.

We have a strong network of reliable suppliers who manufacture and supply quality sintered bushings efficiently. We execute orders timely and strictly adhere to the required quality standards. We offer constant feed back to our clients on the status and progress of the contract.  

We provide all quality test reports and certificates for the sintered bushings as applicable to the contract. We encourage for third-party inspection of the bearings to ensure quality bearings are dispatched.

We provide seaworthy packing for sure and safe delivery of the sintered bearings to the client.

Wrapped bronze bushings are ideal for use in harsh environments where frequent maintenance is not practicable. Wrapped bronze bushings are composed of tin-bronze and have diamond oil sockets or holes drilled into their surface for oil conservation. Its anti-fatigue, anti-erosion, anti-abrasion, and load capacity are all excellent. Their adaptability and long-term success can be attributed to their simplicity, efficiency, and ability to take up space or protect the shaft. Wrapped bronze bushings are used in applications like agriculture machinery, construction equipment, offshore machinery etc.

Wrapped bronze bushings are made from strips that are subsequently wrapped into shape and calibrated. These bearings are available in cylindrical and flanged cylindrical shapes.
