Precision-engineered shafts that support and position planet gears within planetary gear systems, enabling torque transmission and load distribution.
Planet gear pins/shafts are critical rotating components in planetary gear carriers that serve as mounting points for planet gears. They provide precise radial positioning, rotational support, and torque transfer between the sun gear and ring gear. These shafts must maintain exact alignment under high cyclic loading while minimizing friction and wear in the gear mesh interface.

They provide rotational support and precise positioning for planet gears while transmitting torque between the sun gear and ring gear in planetary gear systems.
Case-hardened alloy steels provide surface hardness for wear resistance while maintaining a tough core for impact resistance, ensuring durability under high cyclic loading conditions.
Common failures include surface pitting from fatigue, bending from overload, wear from inadequate lubrication, and fretting corrosion at mounting interfaces.
