Lynx Extended Pitch Roller Chain
Extended pitch (also called double-pitch) roller chain has the same roller dimensions and basic geometry as standard ANSI chain but with twice the pitch distance, fewer rollers per foot of chain. The reduced roller count and longer pitch make extended pitch chain ideal for slow-speed conveyor applications where standard chain offers more capacity than needed. Lynx extended pitch chain follows ANSI B29.4, sized C2040 through C2160 with attachment options for conveyor flights.
Key Features
- ANSI B29.4 double-pitch standard
- Sizes: C2040, C2050, C2060, C2080, C2100, C2120, C2140, C2160
- Larger rollers (D series) and standard rollers (C series)
- A1, A2, K1, K2 attachment options for conveyor flights
- Lower cost-per-foot than equivalent standard pitch chain
- Single, double, and triple strand available
Common Applications
- Slow-speed conveyor drives
- Material handling at moderate loads
- Packaging machinery transport sections
- Food processing conveyors (gentle handling)
- Light manufacturing line conveyors
- Pallet and tray transport
Frequently Asked Questions
What does C2040 mean compared to standard #40?
C2040 has a 1" pitch (twice #40's 1/2" pitch), but uses the same roller diameter as #40 (5/16"). The "2040" designation reflects this: pitch is 2× the standard #40 pitch. Tensile strength is similar to #40 because rollers and pins are the same, you're just using fewer per foot of chain.
When should I choose extended pitch over standard pitch chain?
Extended pitch is economical when (1) chain speed is below 300 ft/min, (2) loads are moderate, and (3) you don't need the smooth engagement of high roller count. Common in conveyor drives where slow speed and moderate load are typical. For high-speed, high-load drives, stick with standard pitch: the smoother engagement is worth the extra cost.
What's the difference between C and D series extended pitch?
C series uses standard ANSI roller diameter (the same as the matching standard pitch chain). D series uses larger rollers, closer to the pitch length, for applications where the chain rides directly on rails or surfaces between sprockets. Choose D series for rail-supported conveyor applications, C series for sprocket-only drive arrangements.
What are A and K attachments?
A and K attachments are special plates that replace standard side plates at regular intervals, providing mounting points for conveyor flights, slats, or buckets. A-attachments protrude on one side (single-sided mounting); K-attachments protrude on both sides (double-sided). Numbers (A1, A2, K1, K2) refer to the size and shape of the attachment ear.
