About

About Glebus Alloys LLC USA Glebus Alloys – Engineered Precision for the Rubber Industry Glebus Alloys is a global manufacturer of advanced self-lubricating bearing materials and tire mold technologies, proudly serving the rubber industry for over 30 years. As both the developer and the producer, Glebus maintains full control from material science through finished component manufacturing, ensuring unmatched quality, performance, and consistency for customers worldwide. Our flagship G-Metal® product line is a specialized family of bronze-graphite alloys manufactured exclusively by Glebus. Designed for high-load, high-temperature environments, G-Metal provides exceptional wear resistance and extended service life without the need for external lubrication. These materials are trusted in tire presses, curing equipment, and other heavy-duty industrial applications where uptime and reliability are essential. Glebus is also the original manufacturer of GSV® Spring Vents, the industry standard in tire mold venting. GSV technology delivers consistent airflow, longer cleaning cycles, and cleaner tire surfaces than conventional micro-vents, allowing for lower rolling resistance and better uniformity. By reducing defects and increasing throughput, GSV enables tire plants across the globe to achieve higher efficiency and superior product quality. Glebus has developed Nano DOT™ Mold Inserts, a next-generation solution for low cost quick precision insert changes in complex mold geometries. Engineered and manufactured in-house, Nano DOT inserts ensure clean, reliable molding with minimal maintenance, allowing tire manufacturers to avoid costly recalls due to incorrect plug positioning, while still preserving tire appearance and consistency. With three decades of experience, global production capabilities, and a commitment to technical innovation, Glebus Alloys provides solutions that help tire manufacturers reduce costs, extend mold life, and improve production performance. At Rubber Expo 2025 in Cleveland, Glebus invites industry leaders to explore how G-Metal, GSV, and Nano DOT technologies are powering the future of tire mold reliability and efficiency.
