03 Cylindrical roller bearing 圆柱滚子轴承
圆柱滚子与滚道为线接触轴承。负荷能力大,主要承受径向负荷。滚动体与套圈挡边摩擦小,适于高速旋转。根据套圈有无挡边可以分有NU、NJ、NUP、N、NF等单列圆柱滚子轴承,及NNU、NN等双列圆柱滚子轴承。该轴承是内圈、外圈可分离的结构。内圈或外圈无挡边的圆柱滚子轴承,其内圈和外圈可以向轴向作相对移动,所以可以作为自由端轴承使用。
主要用途:大中型电动机、机车车辆、机床主轴、内燃机、发电机、燃气涡轮机、减速箱、轧钢机、振动筛以及起重运输机械等。
Cylindrical rollerand raceway line contact bearings.Large load capacity, mainly bear radial load. Small friction between the rolling body and the rim of the ring, suitable for high-speed rotation. According to whether the ring has retaining edge or not, it can be divided into single row cylindrical roller bearings such as NU, NJ, NUP, N and NF,and double row cylindrical roller bearings such as NNU and NN. The bearing is a separable structure with inner ring and outer ring. The cylindrical roller bearing with inner ring or outer ring without retaining edge, the inner ring and outer ring can move relative to each other in axial direction, so it can be used as free end bearing.
Main use: large and medium-sized motor, rolling stock, machine tool spindle, internal combustion engine,generator, gas turbine,reducer, rolling mill, vibrating screen and lifting and transportation machinery.

Cylindrical roller bearing 圆柱滚子轴承
圆柱滚子与滚道呈线接触,径向载荷能力大。既适用于承受重载荷与冲击载荷,也适用于高速旋转。
圆柱滚子轴承滚道及滚动体呈几何形状。经改进设计后,具有较高的承载能力,挡边和滚子端面的新型结构设计,不仅提高了轴承的轴向承载能力,同时改善了滚子端面与挡边接触区域的润滑条件,提高了轴承的使用性能。
单列圆柱滚子轴承:单列圆柱滚子轴承是可分离轴承,便于安装和拆卸,两个套圈都可以采用紧配合,修正的滚子和滚道之间的接触线可以减小应力集中。
圆柱滚子轴承-N系列
N型轴承的外圈无挡边,内圈的两侧有挡边。可以允许轴相对轴承座之间在轴向两个方向上的位移。因此,该类结构适用于作为游动端轴承使用。
圆柱滚子轴承-NJ系列
NJ型轴承的外圈两侧有挡边,内圈单侧有挡边。可以承受一定量的单向轴向负荷。也可承受一定量的单向轴向负荷。因此,该类结构适用于作为单方向的轴向定位轴承用。
