Carbon Graphite Bushes
Engineered Carbon Graphite Bushes for Reliable Dry & Lubricated Applications
At GSI – Globe Seal Industries, we design and manufacture premium carbon graphite bushes that deliver outstanding performance in demanding operating environments. With superior self-lubricating properties, excellent thermal stability, and chemical resistance, our bushes are trusted across industries for applications where traditional metal bearings cannot perform effectively.
Product Overview
Carbon graphite bushes are critical components in pumps, compressors, mixers, and other rotating equipment. They excel in handling applications with high temperatures, corrosive media, or where lubrication is difficult or undesirable.
At GSI, we offer precision-machined carbon bushes that ensure low friction, minimal wear, and consistent performance even under challenging process conditions.
Key Features
✔ Self-Lubricating: Ideal for dry running applications where oil or grease cannot be used, reducing maintenance and contamination risks.
✔ High Temperature Capability: Operates reliably at temperatures exceeding 400°C, depending on grade and design.
✔ Chemical & Corrosion Resistance: Withstands aggressive acids, alkalis, solvents, and process fluids where metal bushes fail.
✔ Excellent Thermal Conductivity: Efficiently dissipates heat, protecting shafts and surrounding components.
✔ Dimensional Stability: Maintains integrity under thermal cycling and mechanical stresses.
Materials of Construction
We manufacture bushes from a wide range of resin- or metal-impregnated carbon graphite grades, tailored for specific operating conditions:
Pure Carbon Graphite: For dry or lightly loaded applications requiring chemical resistance.
Resin-Impregnated Grades: Enhanced strength and reduced porosity for vacuum or low-lubrication services.
Metal-Impregnated (Antimony, Copper): For improved thermal conductivity, load capacity, and dimensional stability.
Our experts will help you select the right grade based on your speed, load, fluid, and temperature requirements.
Applications
GSI carbon graphite bushes are widely used in:
Centrifugal & Submersible Pumps: As bearing bushes and throat bushings for corrosive or abrasive fluids.
Mechanical Seals: As stationary or rotating seal faces and guide rings.
Mixers & Agitators: Supporting shafts under dry or semi-lubricated conditions.
Compressors & Blowers: Providing long-lasting, low-friction bearing surfaces.
Chemical & Pharmaceutical Equipment: Where metallic bushes would corrode or contaminate the process.
