Ring Frame Bottom Roller
Bottom rollers for ring-spinning drafting positions. Identify the front, middle or back position and the installed roller reference before selecting a replacement.
Application
Ring-frame bottom rollers work with the top rollers and aprons to control the fibre strand through the drafting zone. The front, middle and back positions can have different working zones, support locations and end connections. Keep each position separate on the enquiry so a complete set can be identified accurately.
Reference specifications
| Parameter | Details |
|---|---|
| Machine process | Ring spinning / ring-frame drafting |
| Drafting position | Front, middle or back; state the required position |
| Working profile | Flute or knurl profile and pitch from the original roller |
| Body and working lengths | Provide overall length and each working-zone length |
| Journal and bearing seats | Provide seat diameters, lengths and shoulder locations |
| End connection | Provide coupling / thread details and orientation |
Order details
- Identify each roller position separately when ordering a full-frame set.
- Record the number of roller sections and the required quantity for each reference.
- Include a drawing or clear views of the working surface, journals and coupling ends.
Ring Frame Bottom Roller Selection
Start with the machine nameplate and the roller removed from that drafting position. Compare its working diameter, flute form, journal spacing and coupling ends rather than choosing from its overall appearance. If more than one machine model is involved, label the drawings and quantities separately. A complete reference avoids mixing front, middle and back roller sections in one order.

Ring Frame Bottom Roller — Frequently Asked Questions
Which ring-frame roller position should I specify?
State front, middle or back and include the original roller reference. The positions can differ in working length, profile, support spacing and coupling details.
Which dimensions are needed for a ring frame bottom roller quotation?
Send the working diameter, overall length, working-zone lengths, journal sizes and coupling or thread details, together with the machine make, model and quantity.
Does one bottom roller fit every ring frame?
No. Roller geometry and the drafting arrangement vary. Quote each machine and roller position separately so the supplied configuration can be defined.
Should the roller bearing be included in the enquiry?
Include its reference separately if the bearing support also needs replacement. The roller and the bearing are different parts and should be identified together.
