which are the ratio of the roller length to the diameter of the roller and the diameter of the roller, are called needle roller bearingsThe roller bearings, which are the ratio of the roller length to the diameter of the roller and the diameter of the roller, are called needle roller bearings
The diameter is less than or equal to 5mm, and the length is 2.5 times the diameter of the needle
With thin and long needle bearing roller (roller diameter of D = 5mm, L/D = 2.5, L roller length)
With thin and long needle bearing roller (roller diameter of D = 5mm, L/D = 2.5, L roller length)
