The Hitachi TMX20 Drive Sprocket is a key undercarriage component designed to provide powerful and smooth track drive for your small excavator. Built from high-strength alloy steel, this sprocket delivers remarkable wear resistance, shock resistance, and a longer service life — perfect for heavy-duty applications and tough terrains.
Whether you’re replacing worn components or performing a complete undercarriage overhaul, this drive sprocket is an ideal match for your TMX20, TMX20-2, or TMX20-3 excavator. It guarantees a perfect fit, easy installation, and trouble-free operation under all working conditions.
Material and Heat Treatment — Built to Handle Extreme Conditions
The TMX20 drive sprocket is forged from high-grade steel carefully selected for its toughness and wear resistance. To further enhance its durability, we apply precision heat treatment to harden the surface while retaining a tough, shock-absorbing core.
This specialized process results in a sprocket that can:
- Withstand high loading conditions without deforming
- Resist abrasion and pitting from sand, gravel, and clay
- Provide a strong and reliable engagement with the track links
Every tooth is designed with an optimized profile to maximize contact and minimize stress on the chain — extending the service life of both components.
Tooth Rough Machining
The sprocket blank is machined on a CNC lathe or gear hobbing machine to form the basic tooth profile.
Precision Machining
The inner ring is inserted and the entire part is precisely machined to ensure concentricity and dimensional accuracy.
Drilling
Mounting and lubrication holes are drilled to meet the installation and functional requirements.
Tooth Grinding & Finishing
After heat treatment, the sprocket teeth are ground or polished to remove burrs and ensure smooth engagement.
Surface Cleaning
The sprocket undergoes surface cleaning, removing scale and residue, preparing it for surface treatment.
Painting & Final Coating
The sprocket is coated with durable industrial paint (available in various colors), providing corrosion resistance and a clean, professional appearance.
