Compound Bearings
Compound bearings are solid lubricant bearings that provide continuous lubrication during rotation by filling the space between the inner and outer rings with graphite-based compounds and then solidifying the compounds. They enable long-term use without a need for additional refueling. In particular, compound bearings overcome the limitations of conventional grease, which rapidly deteriorates at high temperatures, as they ensure stable operation from -60°C to 350°C. Through the micro-particle crushing effect and sealing effect of the compound molecules, they extend their life and maintain their performance even in environments where foreign matter penetrates due to high dust levels or exposure to chemicals.

This product is gaining attention in various industries, including steel, glass, ceramics, food, aluminum, automotive painting lines, vacuum-based applications and the manufacturing of anode and cathode materials for secondary batteries. It demonstrates outstanding performance in environments requiring long-term stability such as high-temperature and high-dust conditions, or situations where re-lubrication and maintenance are difficult.
Compound bearings can be applied to various industries without being restricted by types, sizes, materials or quantities. Compound bearings include deep groove ball bearings, miniature ball bearings, angular ball bearings, self-aligning ball bearings, spherical roller bearings, cylindrical roller bearings, tapered roller bearings, self-aligning roller bearings, and unit bearings. Instead of using a graphite segment method, JungHyun Compound has adopted a more robust method of filling the retainer of a bearing with compounds.

JungHyun Compound is a small but strong company in South Korea that has focused exclusively on the field of solid lubricant bearings. Through years of accumulated know-how and continuous research and development, the company has developed and produced its own solid lubricant bearings that maximize bearing life even in extreme industrial environments such as high temperatures and high dust levels. Going forward, it will continue to prioritize product development aimed at boosting customers’ productivity, striving to become the most trusted business partner for customers by leveraging its cutting-edge technology and unparalleled quality.
