随着资源价格的下跌，美国对工业设备的需求下滑，为充分利用设施，日本轴承供应商恩梯恩（NTN）拟于4月起在美国生产驱动轴关键组件。 NTN为全球第四大滚珠轴承制造商，在美国伊利诺斯州拥有一座生产工业机械零部件的工厂。该集团拟为其伊利诺斯工厂配置磨床及其他设备，预计耗资30亿日元（约合2,640美元）。 新的设备将用于生产轴承箱，该轴承箱可使汽车车轴转动更加顺滑。NTN目前主要从日本和中国进口这一组件，计划至2019财年使70%的轴承箱生产转化为美国本土生产。 NTN在全球轴承市场中排名第二，共计占全球市场份额的20%。该集团希望提高在美国的生产效率，高精密外圆磨床报价,大型外圆磨床价格，力争赶超在轴承市场领先的英国吉凯恩（GKN）集团。 本财年该集团在墨西哥和中国的轴承工厂已经准备就绪，并将在美国印第安纳州注资100亿日元（约合8,800万美元）建立一座工厂。NTN还计划在2015-2019财年使其全球产量提高40%；在2017财年使其车轴业务营业利润率达到5%（2014财年仅略超2%）。
