带内圈轻系列实体套圈滚针轴承NKI10/16
XSP 实体套圈滚针轴承结构紧凑,径向尺寸小,负荷容量大,适用于径向轮廓尺寸受到限制的部件中,在轴或外壳有摆动运动的情况下也广泛采用。滚针轴承一般只能承受径向负荷,不能承受轴向负荷。当有轴向负荷时,应和其它轴承组合使用,它不限制轴或外壳的轴向位移。滚针轴承的极限转速较低,在主机转速较高的情况下,应尽量选用带保持架的滚针轴承,和其它类型的滚动轴承相比,在径向尺寸相同的情况下,滚针轴承负荷容量较大,它的刚性较高,但摩擦力矩也较大。此类轴承有很多种结构及尺寸系列,要求轴颈或外壳滚动表面硬度、加工精度和表面粗糙度应与轴承套圈相同。所组装的 G2 级滚针,分组批直径变动量 2µm 以内,除满装滚针轴承外,均采用高刚性保持架,能够正确地引导滚针平行轴线。无内圈滚针轴承 RNA、 NK 型无内圈滚针轴承适用于径向尺寸受限制的部件中,由于无内圈,与其配合的轴颈表面直接滚动面。要求其表面硬度不低于 HRC60,表面粗糙度 Ra 值不大于 0.63µm,该种轴承不限制或外壳的轴向位移,极限转速较高。有内圈滚针轴承 NA、 NKI 型该种轴承由于内圈无挡边,因此可分别安装内圈、外圈、全套滚针和保持架、不限制轴或外壳的轴向位移。由于用保持架将滚针隔开,减少了摩擦,所以可用在转速较高的部件中。
