Strong overload capacity: the planetary roller threaded teeth using micro-convex arc type line, to ensure that the nut, screw, roller engagement friction resistance is small, strong adaptability, axial load capacity.
Ensure that the nut, screw, roller engagement friction resistance is small, strong adaptability, axial load.
Long operation life: the key parts of the nut, screw, roller materials are specialized customized.
Special heat treatment process, high hardness of the working surface, toughness, no creep.
