Reiners + Fürst only uses hardened ball bearing steel of 100Cr6 quality for all rings.
The rings from R+F are manufactured in a LOOP® turning process, tailored to a technological textile application of the rings. The functional surface of the rings is designed with an accuracy that no other turning process offers.
Around the world, R+F is the only manufacturer to produce spinning rings with LOOP® technology:
- LOOP® is an R+F development.
- LOOP® produces spinning rings with the highest precision of the flange structure
- LOOP® ensures precisely the same surface quality for every single ring.
- LOOP® guarantees a 100% quality control of the turning process
R+F has the very best prerequisites for continuously improving the ring surface during the turning process. In combination with the constant drive for optimisation, R+F continues to set higher standards, even for the most demanding technological requirements.
R+F offers three different ring qualities for the different applications and operating conditions:
The selection of the appropriate ring quality depends mainly on the yarn programme as well as the achievable spindle speed and the expected service life of the rings and travellers.
