Industrial AL-STAR 41-1R Roller Chain is an ANSI-standard, 1/2 in pitch single‑strand chain identified as model 41-1R, now offered in a 50 ft length. This chain’s geometry aligns with typical 41-series specs: roller diameter 0.312 in, inner width 0.250 in, pin diameter 0.141 in, plate height 0.390 in, plate thickness 0.050 in, and an overall width of 0.541 in. Designed to mesh with standard 1/2 in pitch sprockets and 41-series components, this AL-STAR chain is suited for longer drive runs or multiple assemblies where a 50 ft supply is advantageous.
