Product Description

PRODUCT DESCRIPTION
Needle roller bearings are roller bearings with cylindrical roller, relative to its diameter, the roller is thin and long.This type of roller is called a needle roller.Although has a small cross-section, bearing still has high load capacity, needle bearing with fine and long roller (roller diameter D 5 mm or less, acuity 2.5 L/D, L) for the roller length, so the radial structure is compact, its diameter and load capacity at the same time, with other types of bearing outside diameter to a minimum, especially suitable for the limited size of the radial installation supporting structure.
