Needle bearings, also known as roller bearings with cylindrical rollers, feature thin and elongated rollers relative to their diameter, aptly named needle rollers. Despite having a smaller cross-section, they boast an impressive load-bearing capacity. Equipped with thin, long rollers (roller diameter D≤5mm, L/D≥2.5, where L is the roller length), the radial structure is exceptionally compact. When comparing bearings with identical inner diameter sizes and load capacities, needle roller bearings have the smallest outer diameter. This makes them particularly ideal for support structures with limited radial installation dimensions.
