Double Sprockets for Two Single Chains \u2014 Synchronised Dual-Chain Drives<\/h2>\n

Double sprockets consist of two single-strand sprockets integrated on a common hub, allowing two independent roller chains to be driven from a single shaft. Unlike duplex sprockets (which drive one duplex chain), double sprockets drive two separate simplex chains \u2014 each chain can have a different tooth count, pitch, or direction. Used where two conveyors, two mechanisms, or a conveyor-plus-timing drive need synchronised operation from one motor. Available in ISO metric and ANSI standards.<\/p>\n

Features<\/h2>\n

🔗 Two independent chains from one shaft \u2014 eliminates need for a second gearbox or motor<\/p>\n

🔄 Different tooth counts possible \u2014 different speed ratios on each chain from same shaft speed<\/p>\n

⚙ Mixed pitches possible \u2014 e.g., #40 on one side and #60 on the other (custom manufactured)<\/p>\n

🔥 Hardened teeth, CNC precision, 0.025mm TIR bore concentricity<\/p>\n

🏭 Single bore and keyway \u2014 both sprockets are precisely aligned and concentric<\/p>\n

Applications<\/h2>\n

Parallel conveyor drives from a common motor, dual-side conveyor belt tracking, combined power-and-timing chain systems, agricultural equipment with multiple chain-driven attachments, packaging machines with synchronised indexing and transport chains.<\/p>\n

FAQ<\/h2>\n
\nDouble sprocket vs duplex sprocket?<\/summary>\n
A duplex sprocket drives one duplex (two-strand) chain. A double sprocket drives two separate simplex chains, which can go to different driven equipment.<\/div>\n<\/details>\n
\nCan each side have different teeth?<\/summary>\n
Yes. Each side can have a different tooth count for different speed ratios. Mixed pitches are also available on custom order.<\/div>\n<\/details>\n
\nStock or custom?<\/summary>\n
Common same-pitch, same-tooth combinations are stocked. Mixed-pitch or unusual tooth count combinations are manufactured to order.<\/div>\n<\/details>\n
\nMax bore?<\/summary>\n
Depends on the smaller sprocket diameter. Contact us with both tooth counts for bore capacity.<\/div>\n<\/details>\n
\nMOQ?<\/summary>\n
One piece for standard combinations. Custom: 1 piece MOQ.<\/div>\n<\/details>\n
