Sprocket Manufacture

Sprocket Manufacture

Up to 500 mm diameter, from one piece onwards — a sample is enough, no drawing needed

We cut sprockets up to 500 mm diameter, as one-offs or small series. The pattern can be a drawing — or the worn original. Pitch and tooth form are taken off the sample so the chain runs cleanly.

Diameter
up to 500 mm
Quantity
from one piece
Pattern
drawing or old part
Keyway
up to 32 mm wide

Sizes and limits

Sprockets are hobbed on the Pfauter P400 — up to 500 mm diameter and 400 kg workpiece weight. The hub bore is turned under the same job number; keyways and splines are slotted or broached on the Hahndorf machine up to 32 mm wide and 200 mm long.

Pitch and tooth form follow your chain, not the contents of our tool cabinet: if a profile is missing, we have the tooling made specially. No job fails here for want of a cutter.

Material

The material is set by your drawing. If there is none, we determine it from the old part and choose material and heat treatment to suit the function — a sprocket in the valve train of a classic engine is specified differently from a drive sprocket on a farm machine. Functional surfaces are ground on request, and we document the work in a measurement report if you want one.

How it works

  1. Send in the sample or the drawing. The old part may be worn or broken. For shipping, see send in your gearbox.
  2. Measuring. Pitch, tooth count, tooth form, hub dimensions and keyway.
  3. Drawing. We produce the CAD drawing in DWG or DXF format. The drawing is yours to keep for later repeat orders.
  4. Manufacture. Turning, gear cutting, keyway, heat treatment, and grinding plus measurement report on request.

What a sprocket costs and how long it takes depends on diameter, pitch, material and quantity. We commit to both in the quotation, once we have seen the sample or the drawing — and we then keep the date.

Typical problems this solves

  • The original sprocket has been unavailable for decades
  • The chain runs rough because tooth form and pitch no longer match
  • There is no standard cutter for the pitch you need

Inquiry

What is on your bench?

Gearbox type and a few lines about your request — that is all we need for a first assessment. A photo helps but is not required. The answer comes from the machinist, not from sales.
