Antimony Impregnated Carbon Graphite Bushings for Submersible Motors

Description

Our Antimony Impregnated Carbon Graphite Bushings are engineered for submersible motors operating in wet, corrosive, or high-load environments. Combining carbon-graphite’s natural self-lubricating properties with antimony’s hardness reinforcement, these bushings eliminate the need for external lubrication while withstanding water immersion, abrasive particles, and temperatures up to 250°C.

Key Features & Benefits

1.Antimony-Reinforced Carbon Matrix

• Material Science: Carbon-graphite base impregnated with antimony (Sb) particles.
• Hardness Boost: Antimony increases surface hardness to 60–70 HRc, reducing wear by 50% vs. standard carbon.
• Corrosion Resistance: Withstands saline water, chemicals, and acidic environments.

2.Self-Lubricating & Low-Friction

• Dry-Running Capability: Maintains low friction (μ 0.1–0.15) without grease or oil.
• Micro-Porous Structure: Traps lubricant for extended service life in intermittent wet conditions.

3.Submersible-Grade Design

• Water Immersion Stability: No swelling or deformation in continuous submersion.
• Abrasion Resistance: Withstands sand, silt, and debris in Sewage pumps and marine applications.

4.Precision Engineering

• Custom Dimensions: Machined to tolerances as tight as ±0.01mm (ID/OD).
• Special Features: Lubrication grooves, flanged designs, or threaded ends available.

5.Factory-Direct Advantages

• Cost Efficiency: 40–60% lower cost than silicon carbide or ceramic alternatives.
• Quality Control: ISO 9001-certified production with material traceability.
• Rapid Prototyping: Samples within 10 days for testing.

Applications

• Submersible Motors: Sewage pumps, deep-well pumps, and marine thrusters.
• Marine Equipment: Ship propulsion systems, offshore platform actuators.
• Industrial Wet Environments: Paper mills, mining dewatering pumps, and chemical processing.
