Graphite Filled Bronze Bushes : Manufacturer and Exporter in India.
Graphite Filled Bronze Bushes are accurately engineered bearing elements that provide built-in self-lubrication. to perform reliably under high load and moderate speed conditions, without the need for external grease or oil. At their core, these bushes feature a robust backing of high tensile manganese bronze, composed of copper, aluminium, iron, manganese and zinc. Solid graphite plugs are inserted at specific angles and densities directly into this bronze matrix, creating a surface that continuously releases lubrication during operation. This makes them highly suitable for applications where external lubrication is difficult and impractical.
The result is a maintenance-free bushing solution that delivers effective wear resistance, reduced friction and a long service life, even in tough environments. Industries dealing with heavy machinery, automotive tooling, injection moulding, water turbines, marine equipment, construction machinery and food processing rely heavily on these graphite impregnated bronze bushings for their dependability. Dust, heat and repeated start-stop movement are common causes of premature bearing failure. Solid lubricant bronze bushes overcome these challenges through continuous solid lubrication and frequent stopping and restarting, where conventional lubricants may not provide reliable performance. Graphite bronze bushes offer a cost-effective and durable alternative to conventional plain bearings. For engineers and procurement teams seeking high-performance dry sliding bushings that minimise downtime and maintenance costs, these components remain an industry-trusted solution.
Case Study :
A leading private industrial firm approached Bearing & Bush Co., a trusted graphite filled bronze bush manufacturer and supplier in Mumbai, for a critical bulk requirement. The company delivered accurately manufactured HBsC4-grade graphite filled bronze bushes with a hardness of 200 BHN, tensile strength of 755 N/m² and load capacity up to 750 N/mm², all within agreed timelines. The client was completely happy with the product quality and prompt execution.
Advantages :
- Service Free Lubrication : Embedded graphite plugs release solid lubricant automatically during operation, reducing the need for external grease or oil application.
- High Load Capacity : Engineered from high tensile manganese bronze, these bushings reliably withstand heavy loads up to 750 N/mm² without structural compromise.
- Resilience : The graphite-bronze matrix minimises metal-to-metal contact, delivering prolonged service life even under continuous sliding motion.
- Thermostability : Performs consistently across high and low temperature environments where liquid lubrication becomes ineffective.
- Corrosion Resistance : These bushes suit wet, humid or dusty industrial conditions where standard bearings fail prematurely due to environmental exposure.
- Clean Operation : Since no external lubricants are required, these dry running bushings are ideal for food processing and clean-room machinery applications.
Technical Specifications :
- Material Grade : Available in high tensile manganese bronze grades, HBsC1, HBsC2, HBsC3 and HBsC4, conforming to KS, JIS and ASTM international standards.
- Chemical Composition : Copper content ranges from 55% to 65%, combined with aluminium, iron, manganese and zinc in exact proportions to deliver superior mechanical strength.
