• 
• Cylindrical Roller BearingsSingle row cylindrical roller bearings' roller and raceway are line contact. Bearings can accommodate heavy loads, radial loads mainly. Roller and ring rib has little friction, suitable for high speed rotation. Depending on the existence of ribs on their rings, cylindrical roller bearings are classified into NU, NJ, NUP, N, NF and other single row cylindrical roller bearings.

• 
• Self-aligning ball bearingsThe outer ring of self-aligning ball bearings' raceway consist of two balls units composed by spheres, inner ring, balls and cage. The curvature center and bearing center line are the same. So the inner ring, ball and the cage can rotate around the bearing center. These bearings can be made into both opened and sealed. Self-aligning ball bearings have two structures: cylindrical bore and taper bore.
