The cylindrical rollers have linear contact with the raceway and can carry heavier radial loads. These bearings can be applied in the conditions with heavy and shock loads. They have less friction and high rotational speed, the limited speed is next to the deep groove ball bearings. The n type and nu type bearings are movable along the shaft. They are able to adapt to the positional changes between the shaft and housing caused by the thermal expansion or the mounting error and are most suitable for free end shafts. It is quite demanding for the process of the shaft and the housing bore. After mounting, the relative skew ness of the outer ring axis should be tightly controlled in order to avoid the concentration of the contact stress. The inner ring and outer ring are separable and are convenient to mount and dismount.
