The 51-tooth gear is an essential part of the planetary reduction gearbox or final drive system in SDLG 50-series wheel loaders. It’s responsible for transmitting rotational power efficiently while resisting wear, shock loads, and misalignment caused by uneven terrain.
When you're dealing with SDLG Model 50 loaders, you need gears that can take on massive torque, frequent directional changes, and heavy-duty working conditions. Our 51-tooth gear, manufactured by Jinjiang Anhai Liancheng Machinery Co., Ltd., is designed to meet the demands of real-world job sites—where failure is not an option.
And yeah, this gear can totally handle the heat.
The 51-tooth gear is an essential part of the planetary reduction gearbox or final drive system in SDLG 50-series wheel loaders. It’s responsible for transmitting rotational power efficiently while resisting wear, shock loads, and misalignment caused by uneven terrain.
Crafted from forged alloy steel and processed using CNC machining, gear shaping, and quenching & tempering treatment, this gear offers both dimensional precision and long-term durability.
51 Hardened Teeth: Optimized tooth profile for high-contact strength and smooth gear meshing.
Heat Treated for Performance: Quenching and tempering ensures HRC 56–60 surface hardness while maintaining a ductile core.
Forged Steel Body: Excellent fatigue resistance and toughness under impact or overload.
Precision Machining: Gear hobbing and grinding guarantee minimal backlash and low noise operation.
Strict QC Process: Includes crack detection, hardness testing, and tooth profile inspection for every unit.
It don’t just work—it works hard.
