We at Bearing and Bush Co, manufacture a wide range of products using high-quality sintered bronze (self-lubricating) raw materials in compliance with IS: 3980:1982 standards. Our product portfolio includes automotive bearings, automotive spare parts, plain and flanged bushes, solid rods, self-aligning bushes, and customized profile components developed as per client drawings or samples. These products find applications across home appliances, the textile sector, and various other industries.
Graphite filled bronze bushes (also called Graphite Plugged Bronze Bushes, Self-Lubricating Bronze Bushes, Or Oilless Bronze Bushes) are heavy-duty plain bearings manufactured from bronze alloy with solid graphite plugs or graphite inserts embedded in the bearing surface. The graphite acts as a solid lubricant, allowing smooth movement without external oil or grease.
Graphite-Filled Bronze Bushes are high-performance bearing components designed to operate in applications where regular lubrication is difficult or impractical. These bushes combine the mechanical strength of bronze with the natural lubricating properties of Graphite to deliver smooth, maintenance-free operation under heavy loads and demanding operating conditions.
Graphite plugged bronze bushes are widely used in industries requiring reliable motion control, reduced friction, and long service life.
Working Principle of Graphite-Filled Bronze Bushes:
The working principle of Graphite-Filled Bronze Bushes is based on solid lubrication technology.
These bushes are manufactured from premium-grade bronze and embedded with specially positioned graphite plugs or inserts. During operation, the graphite continuously releases a microscopic lubricating film onto the shaft surface, reducing friction and preventing direct metal-to-metal contact. This self-lubricating mechanism ensures efficient operation without the need for external oil or grease.
The bush body is manufactured from high-quality bronze, offering High load-bearing capacity Excellent wear resistance Superior corrosion resistance High thermal conductivity Long operational life . This makes bronze an ideal material for industrial bearing applications.
Multiple graphite inserts are embedded uniformly throughout the bronze bush. Graphite possesses excellent self-lubricating properties and performs efficiently under dry running conditions High temperature environments Dusty operating conditions High-pressure applications
When the shaft rotates or slides inside the bush contact pressure is generated. Heat develops between mating surfaces. Graphite releases microscopic lubricant particles. A thin lubricating film forms between the shaft and bush. This lubrication layer ensures smooth movement and significantly reduces friction.
As the machine continues operating Graphite keeps replenishing the lubrication layer. Wear is minimized. Heat generation is reduced. Equipment life increases. This makes graphite plugged bronze bushes ideal for maintenance-free applications.
