needle bearing with cylindrical roller bearings, relative to its diameter, roller is fine and long. This is called needle roller. Although it has a small section, the load bearing capacity of bearing still had high, with thin and long needle bearing roller (roller diameter of D = 5mm, L/D = 2.5, L as the roller length), so the radial structure is compact, the outer diameter of the smallest diameter size and load capacity and other types of bearings, especially for supporting the same, structure to the radial installation size restricted.
