These bearings belong to the removable ones, which are convenient in mounting and dismounting. Cylindrical roller bearings are classified as single row, double row and multiple row, of which the single row cylindrical roller bearings with cage are more applied.

In general, the cylindrical roller bearings can only carry radial loads. Only the single row cylindrical roller bearings with inner rings and outer rings having ribs can a certain smaller amount of constant axial loads or bigger amount of intermittent axial loads be carried. Generally for cylindrical roller bearings the shafts are not allowed to incline to the outer housings. However for single row cylindrical roller bearings, under the condition of light loads, the inner rings and outer rings are allowed to incline to each other for 2'; Under the condition of bigger loads, errors can be allowed to be slightly bigger, but not more than 4'.
