Sintered Bronze Bush By Goa Sintered Products Pvt. Ltd.

Sintered Bronze Bushes are produced by compacting metal powders into the required shape and subjecting them to a heat treatment process to form a continuous metal structure with fine pores to retain lubricating oil.
ADVANTAGES OF SINTERING:
Complex shapes
Sintering allows to obtain complex shapes directly from the compacting tooling, without any machining operation, like teeth, splines, profiles, frontal geometries, etc.
High dimensional precision
Achievable tolerances in the perpendicular direction of compacting are typically IT 8-9 as sintered, improvable up to IT 6-7 after sizing. IT 10-13 is achieved in length depending on the component geometry; additional machining operations can improve this precision.
Excellent surface finish
Surface of sintered components is characterised by the presence of flat areas with very low roughness, interspersed with dips corresponding to the porosity. This surface state is better than that of machined wrought materials, which feature an alternate series of peaks and troughs. The lower peaks presence allows to reduce the run-in time of the components.
Reliability and repeatability on large mass production
The tool stability, the technical complexity of the production devices, and the SPC control system, give high reliability and repeatability to the mass production sintered components.
Self-lubrication
The interconnected porosity of the material can be filled with oils, obtaining then a self-lubricating bearing.
