The Genie 086446.3216.S is an OEM sprocket assembly designed for use on Genie J (Jackshaft), H (H-rail), and GH (next-gen H-rail) commercial door operators, fitted for ANSI #50 roller chain (0.625 in pitch). This variant features a 32-tooth drive sprocket with a 1-inch bore diameter. Selecting the correct tooth count and bore diameter is critical: an incorrect tooth count produces the wrong gear ratio, and an incorrect bore diameter will not fit the operator shaft. The J/H/GH series uses #50 chain and is NOT interchangeable with the MH/MJ series which uses #41 chain. Sold as one sprocket assembly (each).
A: This sprocket is designed for #50 ANSI roller chain with a 0.625-inch pitch. It is NOT compatible with #41 ANSI chain used in Genie MH and MJ series operators. Confirm your operator model before ordering.
A: The suffix encodes the sprocket specification: 32 indicates 32 teeth, 16 indicates the 1-inch bore size in sixteenths of an inch (16/16 = 1 inch), and S denotes the sprocket assembly variant.
A: This sprocket is compatible with Genie J-Series Jackshaft, H-Series H-Rail, and GH-Series next-generation H-Rail commercial door operators that use #50 ANSI roller chain drive systems.
A: No, this 32-tooth, 1-inch bore sprocket is a specific variant within the 086446 product family. Other variants exist with different tooth counts or bore sizes. Always verify the full part number before replacement.
A: Steel construction is standard for this class of commercial operator sprocket, providing the durability and load capacity required for high-cycle commercial door applications.
