Needle bearings are remarkable roller bearings featuring cylindrical rollers that are notably thin and elongated compared to their diameter, aptly termed needle rollers. Despite their minimized cross-section, these bearings maintain an exceptional load-bearing capacity. With roller diameters of D≤5mm and a length-to-diameter ratio L/D≥2.5 (L being the roller length), these thin, long rollers contribute to a compact radial structure. Among bearings with identical inner diameter sizes and load capacities, needle roller bearings boast the smallest outer diameter, making them ideal for support structures with restricted radial installation dimensions.
