Oilite Bushes India

Sintered Bronze Bushes : Manufacturer and Exporter in India.

Sintered Bronze Bushes are self-lubricating bearings manufactured using powder metallurgy and oil impregnation processes. The process begins by compacting specially engineered bronze metal powder under high pressure. The compacted form then undergoes sintering at elevated temperatures, fusing the particles into a rigid, porous matrix. Sizing follows to achieve tight dimensional accuracy and finally, oil impregnation saturates the interconnected pores making these oilite bushes genuinely self-lubricated bearings that release oil automatically during operation. Manufactured strictly as per IS: 3980 : 1982 (Copper Base, Grade I), these sintered bronze bearings deliver reliable, maintenance-free performance in tough environments. Their product range includes plain bushes, flanged bushes, self-aligned bushes, solid rods, plates, sintered bearings and custom-made components. This versatility makes them a preferred choice across industries wherever consistent, low-friction rotary motion is critical.

Case Study :

A Mumbai-based pump manufacturing unit approached Bearing and Bush Company requiring self-lubricating sintered bronze bushes for their high-speed pump assemblies operating continuously at 12,000 rpm. Standard bushes were failing prematurely under load. We supplied oil-impregnated flanged bronze bushes with 6.4 g/cm³ density, 20% oil content and 40 HB hardness, rated for loads up to 28 MPa and temperatures reaching +120°C. Downtime required dropped significantly. The client reordered within three months.

Advantages of Sintered Bronze Bushes :

  •   Self-Lubricating Property : The oil stored inside the porous structure automatically lubricates the bush during operation, reducing the need for external greasing.
  •   High-Speed Performance : These bushes can operate efficiently at speeds up to 18,000 rpm while maintaining stable performance.
  •   Low Maintenance Requirement : The internally retained oil helps reduce frequent maintenance, downtime and servicing costs.
  •   Reduced Wear and Friction : A continuous oil film reduces metal-to-metal contact, helping improve service life and smooth operation.
  •   High Dimensional Accuracy : These bushes are manufactured with accurate dimensions for close-fit applications.
  •   Wide Range of Designs : Sintered Bronze Bushes are available in plain, flanged and customised designs to suit different industrial and automotive applications.
  •   Cost-Effective Performance : Long operational life and efficient manufacturing make them an economical solution for industrial use.
