Bearing introduction

NN型轴承是双列满装圆柱滚子轴承,轴承由一个带中挡边外圈,两个有双挡边内圈的结构型式。滚子由内圈的挡边引导,两个内圈用紧固圈固定在一起。该结构除了可以承受很大的径向载荷和轴向载荷之外,还可以承受倾覆力矩,therefore,常用作固定端轴承使用。 NN型轴承两侧采用接触式密封。轴承内填有润滑脂,润滑脂的工作温度为-50℃至+110℃,但由于受密封材料的限制,轴承的工作温度仅限于-40℃至+312℃之间。在使用工况较好的情况下,带有密封的NNF轴承无需进行保养,若轴承长期处于水汽或污染环境,且为中、高速运转时,可通过外圈上的润滑油槽和润滑油孔对轴承进行补充润滑。

Applications

The rolling element is a radial rolling bearing with cylindrical rollers。The internal structure of cylindrical roller bearing adopts parallel arrangement of rollers,Spacer or spacer is installed between the rollers,It can prevent the inclination of the rollers or the friction between the rollers,Effectively prevent the increase of rotation torque。
