Product Overview

Great Ceramic provides custom boron nitride (HBN) ceramic bushings for high-temperature equipment, electrical insulation, and precision industrial applications. Hexagonal boron nitride (h-BN) offers excellent electrical insulation, thermal stability, low friction, and machinability, making it suitable for specialized components operating under demanding conditions.

We support customized inner and outer diameters, lengths, wall thicknesses, grooves, and surface finishes according to customer drawings and application requirements.

Applications & Industries

Boron nitride ceramic bushings are commonly used in:

• High-Temperature Equipment – insulating sleeves and structural components

• Semiconductor Equipment – thermal processing and electrical insulation parts

• Vacuum Systems – insulating and positioning components

• Electrical & Electronics – high-temperature electrical isolation

• Chemical Processing – components requiring thermal and chemical stability

• Industrial Machinery – low-friction bushings and precision sleeves
