Needle bearings are sophisticated roller bearings featuring slender and elongated cylindrical rollers, aptly named needle rollers. Despite their compact cross-section, these bearings boast substantial load-bearing capacity. The rollers have a diameter D≤5mm, and a length L that is at least 2.5 times the diameter (L/D≥2.5), ensuring a compact radial structure. This design allows for the smallest outer diameter among bearings with equivalent inner diameters and load capacities, making them perfect for support structures with restricted radial installation dimensions.
