Opening Roller Complete Assemblies — Plug-and-Play, Mount and Spin
JSM manufactures ready-to-install opening roller complete assemblies (combing roller complete) for OE rotor spinning machines: precision bearing, roller body and carding clothing pre-installed and dynamically balanced in-house — from CNC machining to DN diamond coating.
Combing Roller or Opening Roller — Same Component, Your Machine’s Language
The same assembly is called a combing roller complete on Schlafhorst Autocoro machines and an opening roller assembly on Rieter and Saurer platforms. Tell us your machine brand and model — we supply the correct configuration and naming for your maintenance team.
Anatomy of a JSM Opening Roller Complete
Every complete assembly leaves the factory as one balanced unit — no pressing, no mounting, no guesswork at your mill.
Precision Bearing
Sealed, life-lubricated ball bearing matched to the machine’s mounting and speed requirements — the foundation of smooth high-speed rotation.
Roller Body / Head
CNC-machined roller body (opening roller head / roller body) with precision fit and concentricity, engineered for stable fibre flow at speed.
Clothing Ring / Wire
Integrated clothing ring or carding wire strip pre-fitted — B174, S21, OB20, OK40, OK61, OS21 profiles with Graf, DN diamond or Cr coating.
Three Ways to Order. One Quality Standard.
Select the product type that matches your replacement or procurement need — every configuration meets the same in-house quality standard.
Opening Roller Complete
Complete assembly with bearing, roller body and carding wire pre-installed and balanced. Plug-and-play replacement — just mount and spin.

Clothing Ring
One-piece precision ring with integrated tooth profile. Superior concentricity for fully automatic machines. B174, S21, OB20, OK40, OK61, OS21 wire types.

Carding Wire / Strip
Individual carding wire strips for roller head re-clothing. Flexible replacement — lower maintenance cost. Graf wire, DN diamond and Cr coating options.
View Carding Wire →Why the Opening Roller Matters
The opening roller is the first mechanical contact point for fibres entering the spinning box.
Fibre Opening Quality
Tooth geometry, surface coating and concentricity directly determine fibre opening quality, neps reduction and yarn evenness. At combing roller speeds of 7,500–9,000 rpm, every tooth profile and coating layer must match your fibre type and production speed.
The Cost of a Worn Roller
A worn or poorly manufactured opening roller causes uneven feeding, excessive fibre damage and higher end-break rates — costing your mill productivity and yarn grade. Downtime for unscheduled replacement is often the biggest hidden cost.
One Balanced Unit
JSM supplies the complete assembly as a single pre-assembled, dynamically balanced unit. No in-house pressing or mounting errors — the three components work as one, reducing vibration and extending service life.
Full In-House Control
From machining to heat treatment to coating, every process step happens inside JSM’s plant. That means every tooth profile and coating layer meets your specific fibre type — batch after batch.

Wire Profile & Coating — How to Choose
Wire profile and coating are matched to your fibre type, yarn count and running speed. The guide below is a practical starting point — our engineers confirm the final specification with your machine model.
| Application | Wire Profile Direction | Coating Recommendation |
|---|---|---|
| Coarse cotton yarns (3–16 Ne) | B174 family — robust teeth for high trash load | DN diamond (HV 1000-1200) for abrasive conditions |
| Medium yarns (16–30 Ne) | S21 / OK40 | Graf metallic card clothing or Cr plating |
| Fine yarns (30–40 Ne) | OK61 fine-tooth profile | DN diamond for long service life at high speed |
| Saurer BD platforms | OB20 / OS21 | Graf wire or DN diamond |
| Polyester & abrasive blends | Confirmed per blend & machine | DN diamond coating (HV 1000-1200) recommended |
| Budget-conscious maintenance | Any standard profile | Cr plating / re-clothing with carding wire strip |
Why DN diamond coating? With a hardness of HV 1000-1200, the DN diamond coating can extend opening roller life several times over standard profiles — fewer changeovers, lower cost per ton of yarn, and more consistent yarn quality between changes.

Frequently Asked Questions
What is an opening roller complete assembly?
It is the ready-to-install unit of the opening roller (combing roller) system: precision bearing, roller body/head and carding clothing pre-installed and dynamically balanced. On Schlafhorst machines it is called a combing roller complete; on Rieter machines an opening roller assembly. Just mount and spin — no assembly work required at your mill.
Which machines are compatible with JSM opening roller complete assemblies?
JSM covers Schlafhorst Autocoro SE7–SE20, Rieter R1/R20/R40/R60/R70/R923 and R35/R36/R37, Saurer BD320/BD416/BD448/BD7, plus Taitan, Jingwei and Rifa OE spinning machines.
Which wire types and coatings are available?
Wire profiles include B174, S21, OB20, OK40, OK61 and OS21. Surface options are Graf metallic card clothing, DN diamond coating (HV 1000-1200) and chromium plating.
Complete assembly, clothing ring or carding wire — which should I choose?
Choose the complete assembly for plug-and-play replacement and minimum downtime. Choose a clothing ring (one-piece solid ring) when you rebuild in-house and need superior concentricity for fully automatic machines. Choose carding wire strips for re-clothing an existing roller head at lower maintenance cost.
Can JSM manufacture according to samples or drawings?
Yes. We reverse-engineer and produce compatible replacement assemblies from customer samples or technical drawings, with 100% inspection before delivery.
How long does delivery take?
Standard models ship within 7–15 days. Custom orders typically take 20–30 days depending on specification.
How do I choose the correct opening roller for my machine?
