The roller is in line contact with the raceway, with large radial bearing capacity, which is suitable for bearing heavy load and impact load.

Small friction coefficient, suitable for high speed, limit speed close to deep groove ball bearing.

N type and nu type can move axially, which can adapt to the change of relative position between shaft and shell caused by thermal expansion or installation error, and can be used as free end support. The inner ring or outer ring can be separated for easy installation and removal. The machining requirements of the shaft and the seat hole are high. After the bearing is installed, the relative deflection of the inner and outer ring axes should be strictly controlled to avoid contact stress concentration.

The double row cylindrical roller bearing with 1:12 taper in the inner hole has adjustable radial clearance and high radial rigidity, which is suitable for the spindle of machine tool.
