Product Parameters

Needle roller bearings

Needle roller bearings are roller bearings with cylindrical rollers. Relative to their diameter, the rollers are thin and long. This type of roller is called a needle roller. Despite its small cross-section, the bearing still has a high load-bearing capacity. Needle roller bearings are equipped with thin and long rollers (roller diameter D≤5mm, L/D≥2.5, L is the roller length), so the radial structure is compact. When its inner diameter size and load capacity are the same as those of other types of bearings, the outer diameter is the smallest, which is particularly suitable for support structures with limited radial installation dimensions.
