Precision 99.7% alumina guide pins, loop guides, eyelet guides and take-up winder inserts with controlled yarn-contact geometry for Barmag synthetic filament machinery.
High-purity alumina ceramic gives a smooth, low-friction yarn-contact surface that resists groove wear far longer than metal or plastic guides.
Every insert in this range shares the same 99.7% alumina specification, but the geometry varies by position: guide pins for straight-line contact, loop guides for direction change, eyelet guides for a fully enclosed yarn path, and precision inserts for take-up winder and profile-guide assemblies. Selection is by slot width, radius, overall profile, hole pattern and assembly position — never by product photograph alone.
Dimensions in millimetres. Drawings not to scale — confirm OEM reference and installation position.

A guide pin gives straight-line yarn contact along its length. A loop guide changes yarn direction across a curved contact surface. An eyelet guide fully encloses the yarn path through a bore, used where the yarn needs to be captured rather than just deflected.
Yes. Several inserts in our range (the precision ceramic guides and take-up winder inserts) are matched by physical dimension and drawing rather than a published OEM code. Send a photograph, sketch, or the worn part itself and we'll confirm the closest match from our reference set.
This range is standardised on 99.7% alumina for its wear-resistance and yarn-contact properties. If your application needs a different ceramic grade, raise it in your enquiry and we'll confirm feasibility.
