Lynx ANSI Roller Chain
Lynx ANSI standard roller chain covers the full B29.1 size range from #25 (1/4" pitch) through #240 (3" pitch): the workhorse of industrial power transmission. Available as continuous reels for cut-to-length installation and as individual connecting links, offset links, and connecting pins for repair and modification. Construction follows the HD (Heavy Duty) series with cottered or riveted connections, in steel, stainless, nickel plated, and Dacroclad-coated variants.

Frequently Asked Questions
What does ANSI B29.1 mean?
ANSI B29.1 is the American National Standard for Inch Series Precision Roller Chain. It defines dimensional tolerances for chain pitch, roller diameter, pin diameter, and side plate dimensions. Any B29.1-compliant chain from any manufacturer in a given size will mate with B29.1-compliant sprockets, that interchangeability is the value of the standard.
How do I know what size chain I need?
Look at the chain itself: most has the ANSI number stamped on outer link plates (40, 60, 80, etc.). If unmarked, measure pitch (pin center to adjacent pin center), this number defines the size. Pitch in 1/8" increments: #25 = 2/8" = 1/4", #40 = 4/8" = 1/2", #80 = 8/8" = 1", #100 = 10/8" = 1-1/4", etc.
What's the difference between standard and Heavy series?
Heavy series chain (designated with "H" suffix, 60H, 80H, 100H) uses thicker side plates than standard chain of the same pitch. Result: 20-30% higher tensile strength and improved shock loading capacity, but same dimensional envelope. Heavy series mates with standard sprockets in the same pitch. Use Heavy series in high-shock, high-load, or extended-life applications.
Should I choose cottered or riveted chain?
Riveted chain has solid permanent connections, slightly higher strength and better suited for high-speed continuous operation. Cottered chain uses cotter pins through drilled holes, making it field-serviceable: you can disassemble and reassemble in the field with hand tools. Choose cottered for maintenance-accessible applications, riveted for set-and-forget high-speed drives.
