Needle bearings are an exceptional type of roller bearing equipped with cylindrical rollers that are remarkably thin and long relative to their diameter, aptly called needle rollers. Despite their slender cross-section, these bearings offer an impressive load-bearing capacity. Equipped with these thin, elongated rollers (with a roller diameter D≤5mm, L/D≥2.5, L being the roller length), needle roller bearings boast a compact radial structure. When comparing inner diameter size and load capacity with other bearing types, the outer diameter of needle roller bearings is the smallest. This makes them particularly ideal for support structures where radial installation dimensions are constrained.
