Frequently Asked Questions (FAQ)

What are sintered self-lubricating bushes?

Sintered self-lubricating bushes are precision bearings made from porous powdered metal impregnated with lubricating oil. This structure enables them to provide continuous lubrication during operation, reducing maintenance needs.
How do self-lubricating bushes work?

During operation, the heat and motion cause oil stored within the bush’s pores to flow to the surface, creating a lubricating film between the moving parts. When the motion stops, the oil is reabsorbed into the pores, ensuring readiness for the next cycle.
What applications are best suited for these bushes?

They are ideal for applications where regular maintenance is difficult, such as in electric motors, pumps, household appliances, conveyors, and automotive components.
Why choose sintered bushes from Growth Industries?

We combine precision powder metallurgy techniques with high-grade materials to produce bushes with excellent dimensional stability, wear resistance, and long operational life. Our products are trusted across diverse industrial sectors.
Are self-lubricating bushes maintenance-free?

Yes, in most applications they operate without additional lubrication, which minimizes downtime and reduces operating costs. However, maintaining clean operating conditions will further extend service life.
What materials are used in manufacturing?

Common materials include bronze, iron, or a blend of metal powders, selected according to load capacity, speed, and environmental conditions. Bronze bushes are often used for higher-load applications, while iron-based bushes are more economical for general use.
Can they be customized?

Absolutely. We provide custom sizing, material blends, and oil impregnation options to meet the specific requirements of our clients’ machinery.
How long do they last?

The lifespan depends on the load, speed, and environmental conditions, but their self-lubricating property ensures a significantly longer service life than conventional plain bearings under similar conditions.
