No chain to read?

Measure the old sprocket across two opposite tooth tips and count its teeth. The generator tells you which chain it takes.

What you get

• A cut-ready DXF: the ISO 606 tooth as true arcs, with an over-pins check and the plate you need, printed on the file.
• A STEP solid at the ISO tooth width, for your CAD.
• The plate to buy and the band to grind it to.

Why this one is different

• 1Starts from the chain in your handChain number and tooth count. No pitch tables. No chain to read? Measure an old sprocket and it identifies the chain.
• 2The ISO 606 tooth, drawn exactlySeat, flanks and tips are true arcs worked from the standard's own formulas, in the middle of its tolerance band. No splines, no polylines: the DXF runs on an old G-code control as it is.
• 3A check you can measureEvery file carries the over-pins dimension and its ISO tolerance. A thermal cut is not guaranteed to it, so the part proves itself on the bench.
• 4Plate you can actually buyThe file names the stock plate, the EN 10029 class that guarantees it, the band to grind both faces into and the flatness. Hardened wear plate is waterjet only, because a laser softens the flank the roller wears on.
• 5Lightening holes, checkedOn large sprockets, round holes are offered only where our finite-element check shows the lightened web is stronger than the chain that drives it.
• 6Says no, and says whyIf a sprocket cannot be cut, you are told which input to change and what to change it to.
• 7Free, no sign-upDXF and STEP.

How are these checked? The methods, the validation and what we deliberately do not claim, for gears and sprockets alike.
