工作台主轴用长支承距上下两端各一套双列短圆住滚子轴承，保证在高处加工亦能在高精度下平稳的工作。
Supported by a long table spindle from the upper and lower ends of a double row of the short-lived circular roller bearings to ensure that height in the high-precision machining can under steady work.
上下轴用滚珠轴承支承，同步齿形带传动。
The arm shaft shaft and hook shaft are supported by ball bearings.
同时，设在上下支承辊装置侧面或机架上的压紧缸、腰块上的移动缸可实现轧辊轴承座与机架间的无间隙轧制。
In addition, using the hold down cylinder, the waist block and the shift cylinder can realize gap-less rolling.
