The 67:50 spline gear is a critical part of the power transmission system in SDLG (Shandong Lingong) 50 series loaders. Made from forged alloy steel, it is precision-machined using CNC gear hobbing and broaching techniques. It’s then quench-tempered to deliver both surface hardness and inner core toughness.
In high-load applications like SDLG Model 50 wheel loaders, every gear-to-shaft connection needs to be exact—and strong. Our 67:50 spline gear, manufactured by Jinjiang Anhai Liancheng Machinery Co., Ltd., is designed for maximum torque transfer, tight spline engagement, and long-term reliability.
This gear combines 67 outer teeth with a 50-spline inner bore, offering a perfect fit for SDLG final drive and transmission systems.
When power needs to move without slip or failure—this is the gear you count on.
