SGO participated in SIMTOS 2026, Korea’s largest manufacturing technology exhibition, held from April 13 to 17. With approximately 1,300 companies from 30 countries and over 100,000 visitors in attendance, the event was especially meaningful thanks to the strong interest and support shown by those who visited the SGO booth.

Held under the theme “AI Autonomous Manufacturing, Connecting Talent,” the exhibition highlighted key technologies shaping the future of manufacturing, including digital transformation, industrial robotics, IIoT, and smart processes. SGO showcased a range of products applied across various industries, including brass oilless bearings, sintered bi-metal bearings, and extruded brass materials used in injection molding machines, presses, molds, and power plant facilities.

SGO has developed a next-generation bearing technology for industrial machinery and successfully completed its patent registration on April 6.

This patent covers a material technology that enhances bearing performance under high-load, oil-free conditions and can be applied to industrial machinery requiring high surface pressure, such as injection molding machines and excavators.

Conventional brass-based oilless bearings have faced several challenges under high-load conditions.

In the absence of lubrication, the coefficient of friction increases sharply, leading to excessive wear and heat buildup, which significantly reduces bearing lifespan.

Recognizing these industry challenges, SGO initiated the development of a fundamental solution at the material level.

The core competitiveness of this patent lies in its precise control of microstructure and precipitates.

By intentionally forming primary, secondary, and tertiary precipitates within a high-strength brass alloy composed of Cu, Zn, Al, Mn, Fe, Si, Ni, and Cr, the grain structure is refined, achieving enhanced rigidity, reduced friction, and improved thermal management simultaneously.

According to the patent specifications and test results, the bearing body achieves mechanical properties of at least 285 HB in hardness and 850 MPa in tensile strength, while significantly reducing friction coefficient, frictional temperature, and wear.

This indicates stable performance even under long-term, oil-free operating conditions.

This patent represents an integrated material technology combining alloy composition, microstructure control, and precipitate design, demonstrating SGO’s technological differentiation in the industrial machinery components market.
