Sintered Iron Bushes

Oilite Bushes India

Sintered Iron Bushes : Manufacturer and Exporter in India.

Iron sintered bushes are self-lubricating, porous bearings engineered through a precisely controlled powder metallurgy process. Manufactured using iron-based material as per IS: 3980 : 1982, these bushes undergo a four-stage production sequence namely forming (compacting), sintering, sizing and oil impregnation which gives them their characteristic strength and long-lasting lubrication capability. The oil retained within their porous structure releases continuously during operation, reducing the need for external lubrication in most working conditions. The product range covers plain bushes, flanged bushes, self-aligned bushes, oilite bushes, self-lubricated bushes, sintered bearings, solid rods, plates and custom-profile components manufactured to specific drawings or samples. Industries ranging from automotive to packaging machinery use these components where consistent lubrication and low maintenance are important.

Iron sintered bushes support rotational speeds up to 3000 rpm, making them well-suited for moderate-to-high-speed machinery in automotive, industrial and engineering sectors. Equipment designers and procurement teams actively choose self-lubricated sintered bushes where frequent maintenance is cost-inefficient. Their dimensional accuracy after sizing maintains a consistent press fit and stable performance during continuous operation. For buyers sourcing iron sintered plain and flanged bushes in bulk, these components offer a dependable combination of mechanical integrity and self-sustaining lubrication. Iron sintered bushes are commonly used in precision bearing applications, whether the requirement calls for standard dimensions or custom-profile configurations.

Case Study :

A leading private industrial company approached Bearing Engineering Corporation, Masjid Bunder, Mumbai, a trusted iron sintered bushes manufacturer and supplier in India for 5,000 precision iron sintered bushes , operating at speeds up to 3000 rpm, tolerances of ±0.01 mm and load capacity of 14 MPa. Delivered within committed timelines, with IS: 3980 : 1982 compliance fully met, the client reported zero lubrication failures and expressed complete satisfaction with quality and service.
