The Fingertech Needle Roller Bearing SCE86 (0.500in) is designed for applications where space is limited, providing robust support for motor and weapon shafts. Its thin cylindrical rollers allow for a minimal increase in bearing hole size relative to the shaft, while offering a significantly higher load capacity compared to ball bearings. Constructed from chrome steel and oiled for longevity and high rotational speeds, this bearing is ideal for demanding environments. Note: Ensure the use of a hard inner shaft to prevent deformation from impacts.
