滚针轴承的特点及用途:
滚针轴承装有细而长的滚子(滚子长度为直径的3~10倍,直径一般不大于5mm),因此径向结构紧凑,其内径尺寸和载荷能力与其他类型轴承相同时,外径最小,特别适用于径向安装尺寸受限制的支承结果。根据使用场合不同,可选用无内圈的轴承或滚针和保持架组件,此时与轴承相配的轴颈表面和外壳孔表面直接作为轴承的内、外滚动表面,为保证载荷能力和运转性能与有套圈轴承相同,轴或外壳孔滚道表面的硬度,加工精度和表面质量应与轴承套圈的滚道相仿。此种轴承仅能承受径向载荷。
滚针轴承的类型:
除了型录所列,可用于一般工程的轴承,如:敞开式冲压外圈滚针轴承(1)、封闭式冲压外圈滚针轴承(2)、具内圈滚针轴承(3)和不具内圈滚针轴承/无内圈无保持架滚针轴承(4)、有保持架和无保持架装满滚针轴承(5)SKF还可供应各种类型的滚针轴承,1、滚针保持架组件2、无挡边滚针轴承3、自调心滚针轴承4、组合滚针/球轴承5、组合滚针/推力球轴承6、组合滚针/圆柱滚子推力轴承 STO外圈无挡边,有内圈支承滚轮RNA22...2RS双面密封,无内圈支承滚轮NA22...2RS双面密封,有内圈支承滚轮NATRNATR...PP平挡圈轴向引导支承滚轮NATVNATV...PP平挡圈轴向引导支承滚轮,满针型NUTR滚动体引导支承滚
轮,满滚子型CRY英制平挡圈轴向引导支承滚轮
组合滚针轴承
组合滚针轴承是由向心滚针轴承和推力轴承部件组合的轴承单元,其结构紧凑体积小,旋转精度高,可在承受很高径向负荷的同时承受一定的轴向负荷。并且产品结构形式多样、适应性广、易于安装。 组合滚针轴承广泛用于机床、冶金机械、纺织机械和印刷机械等各种机械设备,并可使机械系统设计的十分紧凑灵巧。
