产品名称：凸键式气胀轴

应用较广泛的收放卷轴，分钢制和铝制两种，使用在对收放卷端面精度一般要求的产品，对于不同材质的卷材，以及卷材的重量、厚度、卷统速度及张力参数的不同，对应的轴体材质厚度，凸键规格及凸键固定盘的材质有所不同。收卷宽幅可按客户要求。具有较高的性价比。
此产品刚性咬合设计，机械锁紧力强，适配重型卷材（金属板/厚膜）及高速设备。

The most widely used winding reels are made of steel and aluminum, and are used in products that generally require precision on the winding end face. For different materials of coils, as well as the weight, thickness, winding speed, and tension parameters of the coils, the corresponding shaft material thickness, convex key specifications, and convex key fixing disk materials may vary. The width of the roll can be adjusted according to customer requirements. Has a high cost-effectiveness.

This product has a rigid bite design, strong mechanical locking force, and is suitable for heavy-duty coils (metal plates/thick films) and high-speed equipment.
