Carbon Graphite Bearings and Bushings

Semicorex graphite bearings and bushings are well-regarded for their outstanding ability to withstand high temperatures, significantly surpassing conventional metal bearings. Unlike metals, which may soften, oxidize or seize up when exposed to heat, graphite maintains its structure, low friction qualities, and mechanical strength even in environments exceeding 300°C. In certain atmospheres, it can endure temperatures above 1000°C. These exceptional properties make graphite bearings suitable for thermal processing equipment, vacuum furnaces, settings involving reactive gases, and industrial equipment with routinely extreme heat.

Carbon graphite bearings and bushings excel in resisting corrosion and chemical damage. They hold up well against acids, alkalis, and harmful gases, making them ideal for use in applications like pumps, valves, and rotating systems that handle aggressive fluids. In contrast to metal bearings that can quickly fail due to oxidation or chemical reactions, graphite demonstrates remarkable durability and consistent performance over time. This advantage reduces the chances of equipment downtime while extending the lifespan of machinery—particularly in settings like chemical plants, salt-bath operations, semiconductor wet benches, and gas-handling facilities. Additionally, one more significant benefit of graphite is its light weight.

Furthermore, carbon graphite exhibits excellent heat resistance. It maintains strong mechanical properties and sliding capabilities across a wide range of temperatures with only minimal thermal deformation. Its low coefficient of thermal expansion combined with high thermal conductivity ensures that the bearings stay accurate and structurally sound even under extreme heat conditions. Moreover, carbon graphite displays impressive resistance to thermal shock during rapid fluctuations in temperature. Unlike metals that may crack or warp when exposed to sudden shifts in temperature, carbon graphite's inherent stability protects it from cracking while ensuring dependable performance.

Additionally, carbon graphite bearings are vital for designing lightweight machinery and equipment, which is particularly important in modern applications. Due to their lower density compared to metals, these materials allow manufacturers to reduce the weight of components, improve energy efficiency, and decrease the overall burden on rotating systems. Moreover, the inherent damping characteristics of graphite help minimize sliding noise levels, leading to quieter operation in settings where sound levels need to be carefully managed.
