1、外圈无挡边N0000型和内圈无挡边NU0000型圆柱滚子轴承此种轴承可接受较大的径向载荷,极限转速高,不束缚轴或外壳的轴向位移,不能接受轴向载荷。
1. This kind of bearing can accept larger radial load, high limit speed, no binding axial displacement of shaft or shell, and can not accept axial load.
2、内、外圈均带挡边的圆柱滚子轴承NJ0000型、NF0000型轴承可束缚轴或外壳一个方向的轴向位移,并能接受较小的单向轴向载荷。NU0000+HJ0000型、NJ0000+HJ0000型、NUP0000型轴承，可在进口轴承的轴向间隙领域内束缚轴或外壳两个方向的轴向位移。并能接受较小的双向轴向载荷。
2. The cylindrical roller bearings nj0000 and nf0000 with both inner and outer ring ribs can restrain the axial displacement of the shaft or the shell in one direction, and can accept small unidirectional axial load. Nu0000 + hj0000, nj0000 + hj0000 and nup0000 bearings can restrain the axial displacement of shaft or shell in the axial clearance field of imported bearing. And it can accept small bidirectional axial load.
