Custom chains, sprockets & gears

When there's no off-the-shelf answer, we supply it: chain assembled and modified in-house, sprockets and gears machined to our specification from your drawing, matched and checked by us.

Cut lengths of attachment chain assembled and laid out on the workshop bench
The gap we fill

Most suppliers sell the nearest standard part. We make the right one.

When a machine needs something that isn't in a catalogue, the usual answer is a compromise: a near-enough chain that wears fast, or a long wait on an OEM special at OEM prices.

We supply the exact part, assembled in our Malvern workshop, with sprockets and gears machined to your specification. You get the part you need, not the closest one, on a UK lead time.

To be clear about what happens in Malvern: we don't manufacture chain components. No forging, no plate stamping.The links themselves are made for us in our partners' ISO 9001:2015-certified factories. What our workshop does is turn those stocked components into your chain: inner and outer links assembled into working chain, cut to the exact pitch count, joined, attachments fitted and specials configured. You get a finished, checked chain built up for your machine, not a box of parts.

What we build

Three disciplines, one point of contact

Chain, sprockets and gears, designed to work together as a matched drive.

Bespoke chain

Standard chain adapted, or a special configured from stocked components.

  • Bent & welded attachments (K, F, G types)
  • Extended, hollow & through-hardened pins
  • Special flights, slats & brackets
  • Non-standard & extended pitches
  • Deep-link & forged-link builds
  • Chain modification, repair & matching to sample

Bespoke sprockets

Cut, bored and hardened to suit the chain and the shaft.

  • Special tooth forms & counts
  • Hardened teeth for long wear life
  • Finished, pilot & taper bores
  • Large-pitch conveyor sprockets
  • Plate wheels & welded-boss designs
  • Laser-profiled to your drawing

Bespoke gears

Gears made to a drawing or reverse-engineered from a sample.

  • Spur & other gear forms to specification
  • Cut to your drawing or a worn original
  • Material and hardness to suit the duty
  • Supplied matched with chain & sprockets
  • One-offs and small batches
  • Gear-cut & machined to our specification
How it works

From worn part to running line

Send us what you have — we'll take it from there.

01

Send it over

A drawing, a photo, a part number, or the worn chain or sprocket itself.

02

We spec it

Our specialists confirm design, material, hardness and tolerances, and flag anything worth improving.

03

We assemble it

Chain assembled in Malvern; sprockets and gears machined by our trusted partners, then checked and matched by us before dispatch.

04

We deliver

Checked, dispatched and repeatable. We hold the spec for your next order.

Capability

The range we can work across

  • Conveyor (BS, ISO, FV)
  • Forged & deep link
  • Leaf & hollow-pin

Attachments

  • K, F & G types
  • Extended & hollow pins
  • Flights & scrapers
  • Special brackets

Materials & finish

  • Carbon / Mn-Cr / Ni-Cr steel
  • Stainless steel components
  • Hardening & heat treatment
  • Zinc plate & coatings

Output

  • One-offs & small batches
  • Matched drive sets
  • Repeat to held spec
  • UK lead times
