Needle bearings, characterized by their elongated, cylindrical rollers known as needle rollers, offer remarkable load-bearing capabilities despite their slim profiles. These needle rollers, with a diameter D≤5mm and a length-to-diameter ratio (L/D) of at least 2.5, contribute to the bearing's compact radial structure. This design allows needle roller bearings to maintain minimal outer diameters while matching the inner diameter size and load-bearing capacity of other bearing types, making them ideal for support structures with constrained radial installation dimensions.
