Grade 80 Links
Pear Shaped Link Forged Weldess Pear links A-341, G-341
A forged pear-shaped link in carbon steel or alloy steel, quenched and tempered for high strength and toughness. Designed for secure connections in chain assemblies, slings, and rigging systems. The pear shape distributes load evenly across the link body, reducing stress concentrations and extending service life. Available in sizes from 3/8 inch to 2 inch, with working load limits up to 51 tons. Finishes include self color or powder coated. Meets ASTM A-341 / G-341 standards.

Key Benefits
What Pear Shaped Link Gives You
- The pear shape spreads load across the link body, reducing localized stress and wear at connection points
- Forged, quenched, and tempered construction ensures high impact resistance and fatigue strength
- Ultimate load capacity of five times the working load limit provides a high safety margin
- Available in carbon steel or alloy steel to suit different load and environmental demands
- Powder coated or self color finish resists corrosion in humid, marine, and industrial environments
- Compact design fits into tight rigging configurations without adding bulk
- Stamps on the body show working load limit and traceability for field use
Application Scenarios
Where Pear Shaped Link Is Used
- Connecting chain segments in heavy-duty lifting systems where load distribution is critical
- Integrating into chain slings and rigging assemblies for construction and infrastructure projects
- Marine and offshore applications where corrosion resistance and high safety factor are required
- Industrial material handling where repeated loading and vibration occur
- Towing and recovery setups using chain systems with high dynamic loads
- Rigging configurations requiring a strong, durable link that resists deformation under side load
Who It Is For
Buyers This Product Is Built For
- Rigging contractors sourcing high-strength links for lifting and rigging projects

How It Compares With The Alternatives
An honest read on where this pattern wins and where another one would serve you better.
| Alternative | Honest Trade Off |
|---|---|
| Standard Round Link | The pear shape reduces stress at the throat and improves load distribution, but round links are more common in standard chain systems |
| Screw Pin Link | The pear link has no pin to back out under vibration, but a screw pin allows for easier disassembly in field use |
| Forged Eye Link | The pear link has a more uniform load path and less sharp bending radius, but eye links are better for hook attachment |
| Non-Heat Treated Link | The quenched and tempered construction gives higher strength and toughness, but non-heat treated links are cheaper and lighter |
Use Guide
How To Use And Inspect Pear Shaped Link
- Verify the stamped working load limit matches the calculated load before use
- Inspect the link for deformation, cracks, or wear before each use
- Avoid side loading the link; keep the pull aligned with the long axis
- Do not use if the powder coating is chipped or the body shows signs of fatigue
- Replace the link if the marking is no longer legible or if it fails a proof load test
- Store in a dry environment to prevent corrosion, especially if not powder coated
