Ring and Ring is a ring spinning machine winding part of the key equipment, to reduce the yarn hairiness, reduce yarn breakage, to extend the exchange cycle of the ring, and lower production costs, the company began in January 2001 in the 20 car trial bearing steel collar. Bearing steel ring spinning performance, we conducted a follow-up observations and testing, and found that its one long life, smooth operation, and cost-effective, and is now gradually to the life cycle of the common flat steel collar to replace the bearing steel ring.

Ring failure of the main wear form is adhesive wear and fatigue wear, bearing steel collar overall hardness reached HV800 above, its high hardness, wear, have shown excellent performance in anti-adhesive wear and fatigue wear. We start from the initial period of every six months on the bearing steel ring once random testing, to observe the operation of the bead flash speedometer and found that the bead smooth operation, smooth running track, rarely fly circle phenomenon, while The ring surface is smooth, non-adhesive material, also found no signs of recession. Ordinary ring in the run-in period, especially 10 months after the operation, the wedge wire circle phenomenon, the increase in flying laps, irregular wave pattern and punctate peeling Road and on the edge of steel, lead, this phenomenon with the extension of the use of time further deterioration, often leading to the generation of cotton balls and yarn defect, serious impact on the quality of yarn.

Bearing steel collar, wide applicability, the fibers and the number of different types can be used, the configuration of the bead with ordinary flat steel collar. The ring surface smooth, small deformation, roundness, flatness, parallelism and so superior to the common plane ring smooth bead orbit, spinning tension and stability, one thousand decapitation hairiness index can be controlled in a relatively a good level. Bearing steel ring contrast with the common plane of ring spinning in Table 1.

Common flat steel collar life in general for about 14 months and every three months or so required under the machine grinding maintenance, frequent replacement, each replacement of a new ring, there is a run-in period, not spinning tension in the run-in period stable, serious yarn hairiness, decapitated, and value the turner labor intensive. Bearing steel rings on the train without maintenance, a one-time continuous use up more than three years without the plane grinding, only special parts staff regularly checks to maintain the stability of production and quality in a relatively long period of time.

Bearing steel ring, good wear resistance, long life, cost-effective. Bearing steel collar price is only about 1.6 times the ordinary planar ring, while the life of the ordinary plane steel collar about three times. The bearing steel licensed conducive to the stability of the yarn quality, while reducing equipment consumption, saves money for businesses to reduce production costs.
