Bearing Steel A Series Wire Straightener Roller

The straightening, consisting of putting the material back into its original shape. The operation is carried out by the first straightening rollers to remove the residual constraint in the material, due to the winding on the bobbin. This operation is performed by the rollers located in the central part of the straightener.The forming of the wire carried out by the last rollers on the straightener, generally placed at an angle of 90°compared to the angle of the first rollers.Often it is necessary to combine these three steps. That is the reason why the straightener uses 5, 7, 9, 11 or even 13 rollers placed in two planes. The manufacturing precision of the roller has a major influence on the quality of the final product (wires) as well as on the service life of the rollers. It is therefore essential that the rectified "V" notch on the outer ring has the same geometric characteristics and precision as the rest of the bearing.
