Product detail · 详情说明
Ring, traveller and spindle must be matched as a system: ring flange diameter, traveller number and spindle speed determine yarn tension and end-break rate. Changing only the traveller on a worn ring is a common cause of persistent breakage.
Give the frame model, ring gauge / flange diameter, yarn count and spindle speed. We match ring, traveller and spindle from the manufacturer table and can quote trial sets by traveller number.
选型与验收要点 / Selection & acceptance points
- Ring, traveller and spindle matched as one system
- Traveller number selected for yarn count and speed
- Ring surface treatment options for the running-in period
- Trial sets by traveller number available on one RFQ

Frequently Asked Questions
Send the part number, a photo of the nameplate / old part, or the machine model and required dimension. We reply with the applicable standard designation and a factory datasheet; the final specification is fixed on the proforma invoice.
Commercial invoice, packing list, certificate of origin, bill of lading or AWB, and an HS-coded technical datasheet. The HS 6-digit heading shown on this page is the international classification; your clearing agent confirms the Pakistan 8-digit PCT subheading and the duty rate applicable on the date of import.
No. The location named under 'Typical sourcing base' is a publicly known industrial cluster, given to help you understand the supply chain. The actual factory, country of origin and any mill / test certificate are confirmed in writing on the quotation and the certificate of origin. Treat it as [待确认] until then.
