Lynx Roller Chain Offset Links
An offset link is a half-pitch chain segment with one inner and one outer link in a single piece: used to adjust chain length by one pitch (rather than the usual two pitches when adding a full pair of links). Indispensable when your drive geometry doesn't fit an even number of standard pitches. Lynx offset links are available in every ANSI pitch from #25 through #240, in single, double, and triple strand. Note: offset links are typically the weakest point in a chain assembly, minimize their use in shock-loaded applications.
Key Features
- Half-pitch length for one-pitch chain adjustment
- All ANSI pitches: #25 through #240
- Single, double, and triple strand options
- Cottered pin construction (standard) or riveted (optional)
- Compatible with HD, XD, SH, and standard ANSI chain
- Field-installable with chain breaker and puller tools
Common Applications
- Adjusting chain length when even-pitch sizing doesn't fit
- Field repair (replacing a single damaged link)
- Take-up adjustment when sprocket position is fixed
- Conversion of even-pitch chain to odd-pitch lengths
- Custom chain assembly for special geometries
- Emergency chain length adjustment in field service
Frequently Asked Questions
Why use an offset link instead of just adding a regular link?
Adding a standard connecting link plus a regular inner link adds two pitches to chain length (since each link is half a pitch and they alternate). An offset link adds just one pitch, useful when your drive geometry calls for an odd number of pitches in the chain. Without offset links, every chain would have to be sized in even-pitch increments.
Why are offset links considered weaker than regular chain?
An offset link is a single piece with both inner and outer link features, it can't use the same construction as a two-piece regular chain section, so its side plates take loading differently. The result is typically 20-30% lower tensile strength than the surrounding chain. For shock-loaded or extreme applications, design to avoid offset links by adjusting sprocket position to fit even-pitch chain.
How many offset links can I use in a single chain?
Best practice: use no more than one offset link per chain loop, since the strength penalty is per-link, not per-loop. If your geometry truly requires two offset links, you can use them but should expect reduced fatigue life and inspect more frequently. Three or more offset links in one chain indicates a design problem, re-engineer the drive geometry.
Can I install an offset link in the field?
Yes, installation uses the same tools as a connecting link (chain breaker to separate chain, then push the offset link into position, secure with cotter pins). Cottered offset links are field-installable; riveted offset links require a rivet press and typically install in a maintenance shop rather than in field service.
