How we work

Our specification.
Our partners' machines.

Dhanush Entech does not run its own foundry or machine shop. We work in tie-up with established manufacturing units in and around Ahmedabad, who produce our range against our drawings, our material grades and our inspection standards. The specification is ours. The machining capacity is theirs. The component that reaches you carries our name and our check.

We're straight about this because it works in your favour. Each job goes to the unit best equipped for it — a heavy split pulley and a small aluminium drill pulley are not the same problem — so you get the right process instead of whatever one factory happens to own. It also means we can hold stock across eight product families and take on non-standard sizes without waiting in a queue.

Ten years of supplying oil mills, textile mills, crusher plants and pump makers across Gujarat means we usually know which component you need from a short description, and we'll tell you if a cheaper one will do the same job.

  • Tie-up units, one point of contact. You deal with us; we handle the shop floor.
  • Standard or to drawing. Send a print or a worn sample — both work.
  • Graded materials. Cast iron, mild steel, EN series steel and aluminium, as specified.
  • Finish machining. Bore, keyway, groove profile and hub style to your requirement.
  • Dynamic balancing. Balanced to suit the running speed of your drive.
  • Checked before dispatch. Material and dimensional reports supplied with the consignment on request.

How to order

Three lines is usually enough

Drawings and worn samples welcome

01

Name the part

Pulley, coupling, sprocket or bush — and the type if you know it. If you don't, describe the drive and we'll work it out.

02

Give the sizes

For pulleys: outside diameter or PCD, belt section, number of grooves, shaft diameter and keyway. For sprockets: pitch, number of teeth, simplex or duplex, hub type. For couplings: bore and keyway of both shafts, plus transmitted kW and running rpm.

03

Send it across

WhatsApp is fastest — a photo of the old part or a drawing works better than a description. We come back with price and delivery.
