Oil Impregnated Bushing │ Self-Lubricating Bearings Manufacturer from Taiwan

JINWOEN is a professional oil impregnated bushing manufacturer in Taiwan, specializing in powder metallurgy self-lubricating bearings designed for long-lasting performance,
low friction, and minimal maintenance.
Our oil-impregnated bushings are engineered with precision to ensure reliable operation across automotive, electronic, and industrial applications.

Product Overview of Oil Impregnated Bushings

Powder metallurgy oil-impregnated bushings, also known as self-lubricating bearings, are designed for durability, low friction, and maintenance-free operation.
During production, fine metal powders are compacted, sintered, and then impregnated with lubricating oil, which is stored within the material’s porous structure.

As the bushing operates, heat and motion cause the oil to be gradually released through capillary action, providing continuous lubrication between moving parts.
This ensures smooth, quiet performance without the need for external lubrication.

These self-lubricating bushings are particularly effective in environments where regular maintenance or re-lubrication is difficult, such as automotive components, electric motors, cooling fans, precision machinery, and pneumatic tools.

At JINWOEN, every oil-impregnated bushing is precisely engineered to deliver superior wear resistance, cost-effectiveness, and long-term reliability for industrial applications.

Key Features of Powder Metallurgy Oil Impregnated Bushings

• Superior self-lubrication with integrated oil reservoirs

• Reduced wear and friction, extending equipment lifespan

• Maintenance-free operation ideal for enclosed or hard-to-reach systems

• Cost-effective design with minimal oil consumption

• Excellent performance in high-load and continuous-use environments

These features make oil-impregnated bushings the preferred choice for manufacturers seeking efficient, sustainable, and low-maintenance solutions.

How Oil Impregnated Bushings Work

Oil-impregnated bushings utilize the capillary action principle:
the microscopic pores within the sintered metal store lubricating oil, which is automatically released during rotation or movement.

This self-lubricating mechanism provides constant lubrication, reducing friction and preventing metal-to-metal contact —a significant advantage over traditional bearings that require periodic re-lubrication.

By incorporating the lubricant during the manufacturing process, JINWOEN’s bushings not only reduce maintenance needs but also optimize oil usage, offering an eco-friendly, high-efficiency design.
