Lynx Roller Chain Connecting Links
A connecting link (also called a master link) joins the two cut ends of a roller chain into a continuous loop after sizing. Three connection types. Cottered Pin (C/P C/L), Spring Clip (S/C C/L), and Riveted, offer different trade-offs between installation ease and joint strength. Lynx connecting links are available in every ANSI standard pitch from #25 through #240, in single, double, and triple strand configurations, matching every chain size we stock.
Key Features
- Three connection types: Cottered Pin, Spring Clip, Riveted
- All ANSI pitches: #25 through #240
- Single, double, and triple strand options
- Compatible with HD, XD, SH, and standard ANSI chain
- Stainless, nickel plated, and Dacroclad options
- Field-installable (cottered and spring clip), shop-installable (riveted)
Common Applications
- Initial chain installation (after cutting to length)
- Field repair of broken chain (replacing damaged links)
- Periodic chain disassembly for maintenance access
- Chain length adjustment
- Replacement of failed connecting links
- Shop fabrication of custom chain assemblies
Frequently Asked Questions
What's the difference between cottered, spring clip, and riveted connecting links?
Cottered Pin (C/P C/L) uses cotter pins through drilled holes to retain the side plate, full strength, semi-permanent (removable with hand tools). Spring Clip (S/C C/L) uses a spring-loaded clip instead of cotters, easier installation, slightly lower strength, faster removal for maintenance. Riveted is a permanent connection requiring a rivet press to install, highest strength, matches riveted chain construction, not field-removable.
Which type should I choose?
For maintenance-accessible drives needing periodic disassembly, choose Spring Clip, fastest in and out. For permanent industrial drives where chain rarely comes off, choose Riveted, strongest connection. Cottered is the middle ground: nearly as strong as riveted, but removable for inspection. When in doubt and the application allows occasional disassembly, cottered is the most versatile choice.
Is the connecting link weaker than the chain itself?
Slightly, in most cases. Spring clip connectors are typically rated 80-90% of chain ultimate tensile strength; cottered pin and riveted connectors are typically 90-100% of chain strength. The connecting link is intentionally the weakest point so it fails first in extreme overload conditions: a controlled failure point that protects more expensive driven equipment.
Can I replace a riveted connector in the field?
Yes, replace it with a cottered or spring clip connecting link of matching size. A field repair using a cottered link is preferable to leaving a broken chain in service. Plan a permanent repair (return to riveted construction in a maintenance shop) when the equipment can be taken down.
