PEEK Nut for Monforts Stenters Black
A PEEK nut is, strictly speaking, the adjustable nut on the stenter's lead rod, the part that lets the guide rail be widened. Because PEEK is self-lubricating it needs no molybdenum disulfide. It is not easy to break, it resists high temperature and corrosion, it wears slowly, and it lasts longer than the part it replaces. PEEK, polyether ether ketone, is a high-performance thermoplastic. It combines high temperature resistance, wear resistance, self-lubrication, low noise, corrosion resistance and high strength, which is why it has spread so widely through textile machinery. This is the black reference for Monforts machines.
Key Benefits
- Self-lubricating PEEK, no molybdenum disulfide needed on the lead rod
- High temperature and corrosion resistant
- Wear resistant, so the width adjustment keeps working through the machine's life
- Sizes 44 x 7, 44 x 6, 45 x 6 and 45 x 6.35, 0.238 kg reference weight
Application Scenarios
- Monforts rail widening mechanisms being rebuilt
- Mills keeping two size batches separated by colour
- Replacing broken nuts that have locked the rail at one width
Who It Is For
- Finishing mills running Monforts stenters
- Maintenance planners keeping colour-coded spares
- Service companies overhauling width adjustment mechanisms
Problems It Solves
- A seized width adjustment nut stopping the rail from being widened at all.
- Molybdenum disulfide grease on the lead rod migrating where it is not wanted.
- Brittle nuts breaking under load and leaving the rail stuck at one width.

How It Compares
| Compared With | What Changes |
|---|---|
| PEEK nut brown reference | Identical function and size range. The colour is there so mills can keep two size batches apart. |
| PEEK buffer block | Different job entirely. The nut adjusts rail width; the buffer block absorbs impact in the chain path. |
Fitting and Replacing This Part
Step 1
Stop the machine and let the assembly cool before stripping it
Step 2
Note the orientation of the part before removing it
Step 3
Clean the seat completely before fitting the new part
Step 4
Fit by hand, without forcing, and check free movement
Step 5
Replace in complete sets so wear stays even across the machine

Oil-Free or Lubricated Stenter Guides
An oil-free guide keeps lubricant away from the fabric using graphite strips and PEEK sliders. A lubricated guide uses a grease film. The chain is different for each, and mixing them is a costly mistake.

Stenter Chain Maintenance and Lubrication
Clean the guide and chain at least once a year, use a high temperature grease, and measure pitch over ten links before you decide to replace anything.
Read GuidePEEK Nut for Monforts Stenters Black Questions
Is the black nut different from the brown one?
Functionally no. Same PEEK material, same size range. The colour helps mills keep batches apart on the shelf.
Why is PEEK used here rather than metal?
PEEK is self-lubricating, high temperature resistant, corrosion resistant and wear resistant, and it does not break easily. That combination is hard to get from metal without grease.
What is the reference weight?
0.238 kg.
Can you make a size that is not listed?
Yes, against a sample. Post us one nut.
