Needle bearings are a specialized form of roller bearings, featuring cylindrical rollers that are notably thin and elongated compared to their diameter—hence, they are dubbed 'needle rollers.' Despite their slender cross-section, these bearings boast impressive load-bearing capacity. Needle roller bearings are crafted with thin, long rollers (with a roller diameter D≤5mm and a length-to-diameter ratio L/D≥2.5, where L is the roller length), offering a compact radial structure. When comparing inner diameter and load capacity with other bearing types, needle roller bearings have the smallest outer diameter, making them ideal for support structures where radial installation space is limited.
