Product Description
wire roller :The wire roller (DL series) is the commonly used component for the wire passing, and it is used in the wire passing position of the coil winding machine and the textile machinery as well. The porcelain ring is trapped out of the bearing, it will rotate by the thread and wire passing on the surface of the ring. Thus the sliding friction has been converted to the static friction. But at the start and stop, in order to overcome the inertia, there will be a partial sliding friction. The difference between the usage of wire roller and ceramic ring is: there is a sliding friction between thread, wire and the surface of the ceramic ring, so it is applied for the smaller angle of the wire, lower pressure and other such kind of less demanding occasions. The wire roller is mainly used of static friction (part sliding friction); it is applied for the bigger angle of the wire, a certain pressure and other such kind of higher occasions. Recently, as improved processing technology, ceramic rings can also be used for important occasions, further illustration will be provided when orders. The surface polish degree of the porcelain ring reaches Ra0.2; the beating during rotation is under 0.15. We select the 99% AL2O3 as the material with the hardness of HRa88 and the density of 3.85. There are three types of the wire roller---wire roller (DL series), ceramic roller (NT-2 series) and the wire jump preventer (NT series). Two nylon sidewalls have been put to the both side of the ceramic ring and the bearing, it combines one wire roller. Two ceramic sidewalls have been put to the both side of the ceramic ring and bearing, there is a reverse hook or a ball to prevent the thread jumping out above the ring. The roller which is without the ceramic sidewalls is called ceramic roller.
