" Commercial Union Service "icon, we will be happy to serve you! Roller cone roller cone according to GB / T 971-94 standard. Specifications Range: M3 ~ M42x3 Accuracy: 1,2,3, respectively, for processing 4,5-level roller cone interface, 5,6-class roller cone manufacturing, 6,7-level external thread rolling wheel thread rolling wheel type by GB / T 971-93 standard A-type screw thread used for right-handed left-hand thread, left hand thread with rolling wheels for right-hand thread. Left-hand thread rolling wheel with the specifications in the back marked "left" word, such as M10 left. The company's rolling wheel using advanced vacuum heat treatment equipment for heat treatment, surface smooth and beautiful, fine microstructure significantly improve durability. Ordering marked Example: rolling wheel type 45 18020-319 M10 40 2 (fine thread pitch size should be raised, for example: M10x1) roller cone must do three things at the center of a straight line, then squeeze the maximum pressure , forming the most complete product. Therefore, adjusting the middle backer pad is very important, is the key operatives proficiency must be adjusted in place, in order to maximize the rolling effect. Patron (bracket) between the middle and there is a bracket holding the product, when rolling, the product between one on the wheel roller cone factory outlets, another section on the backing roller cone, can reduce labor intensity, but also Rolling can effectively improve quality. Advantages: (1) the operator has to rely on when rolling, can reduce labor intensity. (2) to ensure that products and rolling die perpendicular to the plane, to avoid or mitigate the back part produced after Rolling tooth type or shaped into a cone shortage situation.
