Planetary Gear Shaft

This planetary gear shaft is a critical component in any planetary reduction system. It sits in the planet carrier, supporting the planetary gear as it rotates on its own axis. At Yancheng Botu Transmission Machinery, we manufacture this shaft from 20CrMnTi steel. It undergoes carburizing and quenching, followed by precision grinding. The journal surface achieves HRC 58–62 hardness while the core remains tough. This allows the shaft to withstand high contact stress and bending loads from the planetary gear. A robust planetary gear shaft ensures a reliable final drive.

The shaft has a carburized layer of 0.6–1.0 mm, creating a hard, wear-resistant surface. The core maintains 35–42 HRC hardness, providing excellent toughness to resist shock without breaking. Journal roundness is controlled to ≤0.005 mm, ensuring an optimal fit with the planetary gear bushing. This planetary gear shaft is designed to handle the highest torque loads in your machinery.

With 8 years of experience in transmission components, we understand the critical role of the planetary gear shaft in the final drive. We optimize case depth for high-stress applications. Full CNC equipment-including lathes and grinders-ensures precise machining, with journal roundness held within 0.005 mm for a perfect fit with the bushing. Each planetary gear shaft comes with a 1-year warranty, and our fast after-sales service will repair or replace any quality issues free of charge.
