Needle bearings are a type of roller bearing characterized by cylindrical rollers that are exceptionally thin and long relative to their diameter, known as needle rollers. Despite their smaller cross-section, these bearings boast a remarkable load-bearing capacity. The needle roller bearings feature rollers with a diameter D≤5mm and a length-to-diameter ratio (L/D) of at least 2.5, ensuring a compact radial structure. When compared to other bearings with identical inner diameter and load capacity, the needle roller bearing's outer diameter is the smallest, making it the ideal solution for support structures where radial installation dimensions are constrained.
