ELRING Seal Ring Copper Ashape Article number 107.301

Product Overview

The ELRING Seal Ring Copper Ashape Article number 107.301 is a precision-engineered sealing component designed for high-performance applications where reliable fluid containment and vibration resistance are paramount. Crafted from premium copper alloy, this seal ring features an innovative A‑shaped geometry that delivers exceptional sealing force while maintaining low friction during operation.

Design & Material Excellence

The core of the 107.301 is a Copper Alloy (Cu-30% Zn), chosen for its excellent thermal conductivity, corrosion resistance, and inherent ability to form a tight seal under dynamic conditions. The A‑shaped cross‑section provides:

• Uniform Contact Pressure across the sealing surface, reducing wear.
• Enhanced Flexibility that accommodates minor misalignments without compromising integrity.
• Low Friction Coefficient, which minimizes energy loss in rotating assemblies.

Functional Characteristics

This seal ring excels in a variety of operational environments:

• High Temperature Tolerance: Maintains sealing performance up to 200 °C, suitable for automotive and industrial engines.
• Chemical Resistance: Resistant to oils, fuels, and mild acids, extending service life in harsh chemical exposures.
• Vibration & Shock Absorption: The copper matrix absorbs vibrational energy, preventing seal fatigue.
• Low Wear Rate: Copper’s self-lubricating nature reduces abrasive wear against mating surfaces.

Applications Across Industries

The versatility of the 107.301 makes it a preferred choice in numerous sectors:

• Automotive Engineering: Engine oil seals, transmission housings, and turbocharger assemblies.
• Aerospace Components: Fuel lines, hydraulic systems, and turbine seal rings.
• Industrial Machinery: Pumps, compressors, and gearboxes requiring reliable fluid containment.
• Marine Equipment: Propeller shaft seals and ballast system components exposed to saltwater environments.
• Power Generation: Turbine seals in power plants where temperature stability is critical.

Installation Guide

Proper installation ensures maximum performance and longevity:

1. Surface Preparation: Clean mating surfaces with a non‑abrasive solvent to remove oils, rust, or debris.
2. Alignment Verification: Confirm that the shaft or housing is centered; misalignment can lead to premature wear.
3. Seal Placement: Gently slide the 107.301 into its groove, ensuring the A‑shaped profile aligns with the mating surface.
4. Torque Application: Tighten bolts to the manufacturer’s specified torque sequence; over‑torque can deform the copper ring.
5. Final Inspection: Check for uniform contact and absence of gaps before operating the system.

Maintenance & Longevity Tips

To preserve seal integrity:

• Regular Inspections: Periodically check for signs of wear, discoloration, or deformation.
• Avoid Abrasive Contaminants: Keep the operating environment free from grit and particles that could abrade copper.
• Temperature Monitoring: Ensure operating temperatures remain within specified limits to prevent thermal fatigue.
• Lubrication Compatibility: Use compatible lubricants; excessive additives can corrode copper surfaces.

Compatibility & Interchangeability

The 107.301 is engineered to fit standard groove dimensions used in automotive and industrial assemblies. Its A‑shaped geometry allows it to be interchanged with other ELRING seal rings of similar size, providing flexibility for maintenance teams.

Technical Specifications

Performance Benefits

The combination of material properties and geometric design yields several key advantages:

• Extended Service Life: Copper’s resilience to thermal cycling reduces the frequency of seal replacements.
• Reduced Seal Leakage: Uniform pressure distribution minimizes micro‑gaps, ensuring tight fluid containment.
• Lower Maintenance Costs: Durable construction translates into fewer downtime incidents and lower operational expenses.
• Enhanced System Reliability: Consistent sealing performance under vibration and temperature extremes improves overall equipment reliability.

Conclusion

The ELRING Seal Ring Copper Ashape Article number 107.301 stands out as a high‑quality, versatile sealing solution for demanding mechanical systems.
