A carbon blank bush is a raw or unfinished carbon bushing made from materials like carbon graphite or carbon fibre composites, used as a bearing or guide for shafts in rotating or sliding systems. These carbon bushes provide low friction, self-lubrication, and high wear resistance, making them ideal for high-performance industrial applications. Their ability to operate without external lubrication and withstand high temperatures makes them suitable for demanding environments.

Carbon blank bushes are commonly used in automotive systems (e.g., suspension components), marine applications (e.g., propeller shaft bearings), and aerospace/UAVs for lightweight, durable bearing support. They are also effective in high-temperature machinery like furnaces and ovens, and in electrical equipment such as generators and electric motors, where they function as sliding contacts or brushes. Their corrosion resistance and long service life make them a cost-effective choice for a wide range of engineering needs.
