Genie 086565.1033.S is a Genie OEM replacement ansi #25 roller chain loop (ANSI #25 Loop (Endless) Roller Chain - 50 Pitch). This variant has the following dimensions: Pitch: 0.250 in - 50 pitches x 0.250 in = 12.5 in total loop length - Roller dia: 0.130 in - Roller width: 0.125 in - Pin dia: 0.091 in - Overall width: 0.306 in - Plate height: 0.228 in. Construction: Carbon steel - standard finish - no plating. For use with Genie chain-drive residential door operators and Genie chain-drive commercial door operators. Selecting the correct chain ANSI size, pitch count, and configuration (open-ended vs. loop) is critical for proper installation and operator function.
A: This chain has 50 pitches at 0.250 in each, giving a total loop circumference of 12.5 in. It is an endless (loop) configuration with no free ends.
A: The 086565.1033.S is a loop (endless/riveted) chain, meaning the two ends are permanently joined to form a continuous loop. Open-ended variants in the 086565 series use a 0xxx suffix instead of the 1xxx suffix used here.
A: ANSI #25 specifies a 0.250 in pitch, 0.130 in roller diameter, 0.125 in roller width, and approximately 795 lbf tensile strength. It is a light-duty small-pitch chain used in internal drivetrain and auxiliary drive assemblies.
A: This chain is made from standard carbon steel with no special plating or coating. If a corrosion-resistant finish is required, a nickel-plated variant should be sourced separately.
A: The 086565.1033.S loop chain is used in Genie chain-drive door operator assemblies where a continuous drive loop of 12.5 in circumference is required. Always verify the required pitch count and loop vs. open-ended configuration against your specific operator model before ordering.
