The 50-spline internal gear serves as a crucial connecting component between input shafts and the planetary gear system in XGMA and Lonking 50 loaders. It is manufactured from forged alloy steel, and then processed via CNC broaching, quenching, and tempering, resulting in a high-hardness surface and resilient core.
When it comes to power transmission in wheel loaders, nothing matters more than a gear that locks in with zero tolerance and lasts under pressure. Our 50-spline gear, engineered for XGMA and Lonking Model 50 series loaders, is designed to meet the exacting standards of today’s construction machinery.
Manufactured by Jinjiang Anhai Liancheng Machinery Co., Ltd., a leading gear supplier in China, this gear ensures smooth engagement, high torque output, and extended operating life—even under intense load cycles.
No kidding—it fits like a dream and just doesn’t quit.

This part is ideal for applications where precision spline matching, shock resistance, and dimensional accuracy are non-negotiable.
Standard 50-Spline Fitment: Perfectly matched for XGMA and Lonking Model 50 final drive and transmission systems.
Heat-Treated for Durability: Surface hardness up to HRC 58–62; tempered for deep toughness to prevent cracking.
CNC Broached Spline Profile: Maintains consistent engagement and power transfer under continuous operation.
Forged Material Body: High wear resistance and strong impact performance even in extreme field environments.
Quality-Controlled Production: 100% inspected for spline depth, concentricity, and hardness consistency.
It don’t only look solid—it performs like a boss.
This 50-spline gear is used in the power transmission systems of XGMA and Lonking 50-series wheel loaders, commonly seen in construction sites, mining pits, road works, and bulk handling yards. It’s a preferred choice for OEM manufacturers, aftermarket distributors, and international equipment maintenance companies.
