Huahao Sealing · Carbon Graphite Components
SB Series
Graphite bushings (carbon graphite sleeves) are made from high-quality carbon graphite material with excellent self-lubricating properties, temperature resistance, and corrosion resistance. Suitable for supporting and guiding rotating or reciprocating motion components in oil-free or boundary lubrication conditions. Widely used in submersible pumps, wastewater pumps, chemical pumps, and various industrial pumps, operating stably in water, oil, and various chemical media. Custom non-standard sizes supported per drawing.
