NAV3940 NAV3956 NAV4033 NAV4004 NAV4005 NAV4006 Needle Roller Bearing

Needle roller bearings are compact high-load bearings with slender cylindrical rollers. They are specifically designed for mechanical structures with limited radial installation space. The key feature of these bearings lies in the use of slender cylindrical rollers, with a diameter of ≤ 5mm and a length-to-diameter ratio of ≥ 2.5. This special structure enables them to have the smallest outer diameter size while maintaining a compact radial structure and high load-bearing capacity.
