Worm Gear Sets & Gearbox Spares

Matched worm shaft and worm wheel sets for any make of gearbox — phosphor bronze wheels, PB rim re-rimming, shafts, covers, and seal kits from the same shop that builds complete reducers.

Anand Gears matched worm gear set and gearbox spares

Spares Capability

Replace the Mesh — Not Always the Whole Box

When a worm gearbox still has a sound housing but a worn mesh, Anand Gears manufactures a matched worm shaft + worm wheel set to sample or drawing — for our own NU, Adaptable, and NMRV families and for other industrial makes. Sets are supplied as pairs so contact pattern and running-in stay controlled. This service sits alongside full replacement and repair when the housing is not salvageable.

Matched worm + wheel pairs (not mix-and-match)
Phosphor bronze solid wheels or PB rim on CI/steel centre
PB rim re-rimming of existing wheel centres
Spare input / output shafts and bearing covers
Oil seal kits for common industrial sizes
Built to sample or drawing — any make interface

Matched Sets

Worm Shaft + Worm Wheel as a Pair

Hardened worm shafts

Steel worms thread-milled and finished to the lead, starts, and journal steps of your sample or drawing — the same process used on Anand Gears catalogue cast iron worm reducers (50–305CD class sizes on the standard line).

Phosphor bronze worm wheels

Solid phosphor bronze wheels or a PB rim on a cast iron / steel centre — the wear-facing material industry expects on industrial worm meshes. Hobbed to match the new worm as a set.

PB rim re-rimming

When the wheel centre is still true, we can re-rim with new phosphor bronze, machine, and re-cut teeth — often more economical than a full solid wheel where the hub geometry is complex.

Any-make geometry

Centre distance, tooth count, shaft steps, and bore sizes taken from your unit. No need for the original brand name — only the mechanical interface in millimetres.

Input & output shafts

Spare shafts turned and keywayed to match the existing coupling or hollow-bore stack — solid or hollow, single or double output ends.

Covers & seal kits

Bearing covers, end caps, and oil seal kits so a rebuild closes correctly after the new mesh is fitted — discuss sizes with the set RFQ.

How to Order

What to Send for a Matched Set Quote

  1. Sample or drawing — the worn worm and wheel, or measured CD, tooth counts, and shaft steps in mm.
  2. Housing condition — confirm bores and bearings are still serviceable if you plan a field rebuild.
  3. Material preference — solid PB wheel vs re-rim on existing centre (if the hub can be reused).
  4. Spares list — seals, covers, and spare shafts needed at the same time.

FAQ

Worm Gear Sets & Spares — Common Questions

Why are worm and wheel supplied as a matched set?

Worm and wheel develop a contact pattern together. Mixing a new wheel with a worn worm (or the reverse) often causes rapid wear. Anand Gears supplies matched pairs cut and finished to run together.

Can you re-rim an existing worm wheel centre?

Yes. Where the cast iron or steel centre is sound, a new phosphor bronze rim can be cast and machined onto the existing centre, then hobbed to match the mating worm.

Do you need the original brand name for spares?

No. A sample set, measured dimensions in millimetres, or a drawing is enough. Brand names do not drive the manufacturing drawing.
