特点和优势
*低摩擦 (滚子端面/挡边接触区域)
开放式挡边设计,以及滚子端设计和表面光洁度,促进润滑油膜,从而降低摩擦并带来较高的基本额定载荷。
*使用寿命长
滚子对数曲线轮廓减少了滚子/滚道接触处的边缘应力以及对不对中和轴挠曲的灵敏度。
*提高运行可靠性
滚子和滚道接触面的表面处理有利于流体动压润滑油膜的形成。
*可分离和互换
圆柱滚子轴承的分离组件是可互换的。 这样便于安装、拆卸和维护检验。
*高速能力
保持架设计适用于高速、快速加速和最高载荷。
*Features and benefits
*Low friction (roller end/rib contact area)
Open rib design, as well as roller end design and surface finish, promote lubricant film, resulting in low friction and high basic load ratings.
*Long service life
The logarithmic roller profile reduces edge stresses at the roller/raceway contact and sensitivity to misalignment and shaft deflection.
*Increased operational reliability
Surface treatment of roller and raceway contact surfaces promotes hydrodynamic lubricant film formation.
*Separable and interchangeable
Cylindrical roller bearings are interchangeable. This facilitates mounting, dismantling and maintenance inspection.
*High speed capability
The cage design is suitable for high speeds, rapid acceleration and highest loads.
