TURBO rings offer simplified running-in and extremely stable running performance with highest spindle speeds even under most challenging spinning conditions like Compact and Siro-Compact. R+F ring travellers stand out due to most rapidly building up of lubricating film on their con-tact area with the spinning ring. The CERADUR ring and traveller system optimizes capacity utilisation of long ring spinning machines and simultaneously reduces labour costs as well as traveller costs due to ex-tremely long lifetimes.
