PEEK Nut for Monforts Stenters Brown
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 brown reference for Monforts machines.
Key Benefits
- Self-lubricating, so the lead rod needs no molybdenum disulfide
- Resists the high temperature and corrosion around a stenter rail
- Not easy to break under width adjustment load
- Sizes 44 x 7, 44 x 6, 45 x 6 and 45 x 6.35, 0.238 kg reference weight
Application Scenarios
- Monforts width adjustment that has gone stiff
- Rail widening mechanisms being overhauled
- Machines where the old nuts have broken under load
Who It Is For
- Finishing mills running Monforts stenters
- Maintenance teams overhauling the width adjustment
- Machinery dealers stocking Monforts wear parts
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 black reference | Same function and the same size range, a different colour reference. Mills use the colour to tell size batches apart on the shelf. |
| Metal nuts | Metal needs molybdenum disulfide on the lead rod. PEEK is self-lubricating and does not. |
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

Read GuidePEEK Nut for Monforts Stenters Brown Questions
What exactly does the PEEK nut do?
It is the adjustable nut on the setting machine's lead rod. It is what lets the guide rail be widened.
Do I still need to grease the lead rod?
No. PEEK is self-lubricating, so molybdenum disulfide is not required.
What sizes do you make?
44 x 7, 44 x 6, 45 x 6 and 45 x 6.35. Measure your nut and tell us which you need.
Brown or black, does it matter?
Functionally no. Mills use the colour to keep size batches apart on the shelf.
