NEB型侧推式机械夹头 NEB-type side-pushing mechanical chuck 液压纸架最合适之侧推式夹头。 液压支臂移动侧推时，使扇形结构扩张固定料管并自动对心。 较大的接触面积，对料管损伤。 多规格，高承重，免维护，长寿命，操作简单，减少繁重搬运而引起的风险。 Hydraulic pressure paper holder is most suitalbe to side-pushing mechanical chuck. When hydraulic support arm is moved and pushed from side, fanshaped structure expands to fix roll and aligns automatically. Large touching area can prevent roll from damage. It has more specifications, high load bearing, maintance free, long life, simple operation, and reduces risks from heavy handling.
