美国Timken轴承详细介绍
Timken轴承介绍品牌：美国TIMKEN轴承公司名称：美国铁姆肯公司成立时间：1895年公司总部：美国俄亥俄州坎顿市TIMKEN轴承又称铁姆肯轴承，TIMKEN公司总部所在地：美国俄亥俄州坎顿市，一九八五年，铁姆肯公司的创建人亨利·铁姆肯设计了一种带有圆锥滚子的轴承，这是一项革命性的技术设计。
这种被称为“圆锥滚子轴承”的新式轴承首先使用在四轮马车上，显著地降低了摩擦，并于三年后获得了专利。
创业至今，铁姆肯公司稳定发展，成为全球驰名地先进轴承和优质刚才地供应商，为世界各地日益增多的客户服务。
今天，这家上市公司是圆锥滚子轴承和合金无缝机械钢管领域首屈一指的制造商。
铁姆肯生产二百三十种类型、二万六千个不同规格的圆锥滚子轴承，他们被广泛应用于世界各国的汽车、航天、一般工业和铁路工业。
分布在五大洲的二十多家铁姆肯轴承厂均按统一质量标准生产产品。
TIMKEN轴承应用领域：在汽车、铁路、钢铁、机床、飞机、工程机械、农业以及其他工业领域，TMKEN从磁盘驱动器到钻机，从牙科钻头到轧机，只要有轮子或轴在转动，铁姆肯的产品均可提高其性能。
TIMKEN轴承圆锥滚子轴承:铁姆肯公司是当今世界最大的圆锥滚子轴承生产和销售公司并专业研制圆锥滚子轴承，TIMKEN轴承对圆锥滚子轴承的了解程度无与伦比。
现可生产200多个类型近26000个品种的圆锥滚子轴承。
铁姆肯公司在轴承业界享有极高的声誉，不论是生产公司制或英制圆锥滚子轴承，更是不断拓展ISO公制圆锥滚子轴承的产品系列，以满足市场不断变化的需要。
