Long screw shafts for a large twin-screw compounding extruder

We manufacture drop-in replacement screw elements, kneading blocks, shafts and barrels for the Coperion ZSK Mc series, including ZSK 58Mc and ZSK 70Mc, to the same dimensional standard as the original.

ZSK series coverage

Our tooling covers the ZSK Mc and Mc18 ranges. The models below are the ones we supply most often. If your machine is not listed, send a photograph of the nameplate and we will confirm.

  • ZSK 26 / 40 / 50 Mc
  • ZSK 58 / 70 Mc
  • ZSK 92 / 133 Mc
  • Mc18 and Mc11 variants

What interchangeable actually means

Interchangeable means the element fits the shaft, matches the centre distance and reproduces the conveying geometry, so it can run alongside original parts on the same shaft. We work from OEM drawings where they are available and from measured samples where they are not.

  • Same spline and keyway
  • Same outer diameter and pitch
  • Same stagger angles
  • Can be mixed with OEM parts

Verification and documentation

Each shipment includes a dimensional inspection report. On request we supply material certificates to EN 10204 3.1, hardness results and a CMM printout for the batch.

  • CMM dimensional report
  • EN 10204 3.1 certificates
  • Hardness and case-depth records
  • Photographs before packing

ZSK 92 screw element replacement

The ZSK 92 is one of the most common compounding machines in the 92 mm class. We supply replacement conveying elements, kneading blocks and shafts for the ZSK 92 Mc and Mc18, machined to the OEM profile so they fit an existing shaft without modification. Elements can be ordered individually or as a complete screw set.

  • ZSK 92 Mc and Mc18
  • Conveying elements and kneading blocks
  • Individually or as a full set
  • CMM report per batch

ZSK 133 screw element replacement

On the ZSK 133, wear concentrates in the melting and mixing zones where torque and temperature peak. We manufacture ZSK 133 elements in PM-HIP steel and supply them as single replacement pieces or as a matched set for a planned overhaul. Because of the size, freight is quoted separately and a full set is usually shipped by sea.

  • ZSK 133 Mc
  • PM-HIP steel for the mixing zone
  • Single pieces or matched sets
  • Sea or air freight quoted separately

Frequently asked questions

Is it acceptable to run non-OEM parts in a Coperion machine?

Yes. Aftermarket wear parts are standard practice in compounding. Check your service agreement if the extruder is still under warranty, since some contracts restrict third-party parts.

Are ZSK 58Mc and ZSK 70Mc parts interchangeable with each other?

No. The two machines use different screw diameters, so element sizes and barrel bores differ. We tool for both, so quote the machine model with your enquiry.

How quickly can you respond to a breakdown?

Send the machine model, the element position and a photograph. We will confirm availability and the fastest realistic lead time for that specific part.

Do you supply ZSK 92 and ZSK 133 parts together?

Yes, but they are different sizes and are never interchangeable. Quote the machine model for each line separately so we can prepare the correct drawings.
