Needle bearings are roller bearings featuring cylindrical rollers that are notably thin and long relative to their diameter, aptly named needle rollers. Despite their smaller cross-section, these bearings exhibit an impressive load-bearing capacity. Equipped with slender and elongated rollers (roller diameter D≤5mm, L/D≥2.5, where L represents roller length), the radial structure remains compact. When matched in inner diameter size and load capacity with other bearing types, needle roller bearings boast the smallest outer diameter. This makes them exceptionally suitable for support structures with limited radial installation dimensions.
