MIL-B-3990。许多此类轴承设计用作具有厚横截面外圈的滚轮，以承受重滚动载荷。它们是防腐蚀的、油脂润滑的、密封的或未密封的。其他滚针轴承设计用于外壳，并具有润滑孔和凹槽，以便通过轴或外壳润滑。螺柱型凸轮从动件可用于简化配置，同时允许通过螺柱进行再润滑。 这些产品的套圈和滚针由 AISI 52100 高碳铬钢制成，经过硬化和精密研磨。为了防止在重滚动载荷下腐蚀，滚子轴承的外径可以镀铬。凸轮从动件的螺柱由 轴承钢制成，在滚道区域硬化至 60 HRC。暴露的表面可以镀镉或锌镍。 为了提高耐腐蚀性，RBC 还由硬化不锈钢合金、AISI 440C 或 AeroCres® 减少维护、高耐腐蚀钢制成的轴承。 RBC 机身控制滚针轴承可单滚子或双滚子路径、圆柱或凸面外径以及自调心外圈特征。这些轴承通常采用 80% 至 ** 的润滑脂润滑，符合 Mil-PRF-81322 或 Mil-PRF-23827 规范。 美国RBC机身控制滚针滚轮轴 -4 4NBF614YJ 6 6NBF817YJ 8NBF1021YJ 2-3 HRS-1C H 5 HRS-3C HRS HRS-5C HRS-5C HRS-5C 21432-8 HRS-6C RS-1C CHRS-1C CHRS-1C 21447-4

交叉滚子轴承是一种内圈分割、外圈旋转的特殊型号轴承。因被分割的内环或外环，在装入滚柱和间隔保持器后，与交叉滚柱轴环固定在一起，以防止互相分离，故交叉滚柱轴环时操作简单。因为交叉滚子轴承是内圈外圈两分割的构造，所以轴承间隙是可以进行调整的，就算被施加预载也能够高精度地旋转运动，因为架构特殊，所以一般多用于工业机器人的关节轴承，今天就跟大家聊一聊交叉滚子轴承，下面我们就一起来看看吧！ 工业机器人应用较多的轴承主要有两大类：等截面薄壁轴承和交叉滚子轴承。工业机器人的轴承是其关键配套件之一，适用于工业机器人的关节部位或者旋转部位、机械中心的旋转工作台、机械手旋转部、精密旋转工作台、仪器、计量器具、IC装置等广泛用途。 机器人用交叉滚子轴承的优点： 1、具有出色的旋转精度 交叉滚子轴承内部结构采用滚子呈90°相互垂直交叉排列，滚子之间装有间隔保持器或者隔离块，可以防止滚子的倾斜或滚子之间相互摩擦，有效防止了旋转扭矩的增加。另外，不会发生滚子的一方接触现象或者锁死现象；同时因为内外环是分割的结构，间隙可以调整，即使被施加预压，也能获得高精度的旋转运动。 2、操作简化 被分割成两部分的外环或者内环，在装入滚子和保持器后，被固定在一起，所以时操作非常简单。 3、承受较大的轴向和径向负荷 因为滚子在呈90°的V型沟槽滚动面上通过间隔保持器被相互垂直排列，这种设计使交叉滚子轴承就可以承受较大的径向负荷、轴向负荷及力矩负荷等所有方向的负荷。 4、大幅节省空间 交叉滚子轴承的内外环尺寸被小限度的小型化，特别是超薄结构是接近极限的小型尺寸，并且具有高刚性，所以适合于工业机器人的关节部位或者旋转部位、机械中心的旋转工作台、机械手旋转部、精密旋转工作台、仪器、计量器具、IC装置等广泛用途。 美国BARDEN轴承38SSTX6K5CG-76轴承--2分钟前更新 20-L RBC BEARINGS, S-20-LW RBC BEARINGS, S-20-LWX
