Description
This splined pinion shaft is an essential transmission component in radial drilling machines, designed to transfer torque from gears to the arm movement or feed system. Constructed from high-grade alloy steel and hardened for superior durability, it ensures precise engagement with mating gears and long operational life even under heavy industrial loads.
Its precision-ground splines ensure accurate alignment, minimal backlash, and reliable performance.
Usage:
- Used in the arm lifting, feed drive, or transmission mechanism of Z-series radial drilling machines
- Transfers rotation and torque between gears
- Replacement for worn or damaged pinion shafts
- Ensures smooth and accurate mechanical movement
