The YJ series cantilever steel straightening machine is in the form of an upward pressure cantilever, with fast and convenient roll changing.YJ系列悬臂式型钢矫直机形式为上压悬臂式，换辊快速方便。
In terms of equipment transmission, the straightening machine roller shaft transmission distribution is integrated with the main engine, using an external hard tooth surface reducer with a compact structure and small footprint.设备的传动方面，矫直机辊轴传动分配与主机一体式，采用外置硬齿面减速机，结构紧凑，占地面积小。
All straightening machines are supported by rolling bearings, with low friction coefficient, stable performance, and high straightening accuracy.
矫直机全部采用滚动轴承支承，摩擦系数小，性能稳定，矫直精度高。
4.Both the upper and lower roller axles of the straightening machine have axial adjustment mechanisms (manual), and the upper roller axle has a lifting adjustment mechanism (electric) for flexible and convenient adjustment.矫直机上下辊轮轴均有轴向调整机构(手动)，上辊轮轴有升降调整机构(电动)，调整灵活方便。
The main shaft transmission part and external reduction part of the straightening machine are lubricated with thin oil.矫直机主轴传动部分、外置减速部分采用稀油润滑。
