Products information 1)Sprocket material: 35Mn2、40MnB、45#Carbon steel、42CrMo; 2)Surface hardness: Standard HRC50-60; Heavy-duty mining HRC55-62; 3)Tooth Hardening Depth: 18–23mm; 4)Tensile Strength: ≥800MPa; 5)Structure Type: Single Piece/Split Rim ; 6)Pitch Tolerance:±0.1~0.5mm; 7)Package: packed in strong pallets; 8)Application: Drive sprocket is responsible for transmitting the power of the hydraulic motor to the track chain, thereby driving the machine forward or backward.
Long wear parts@ supply drive sprocket is the core power transmission component of crawler undercarriage system, mounted on final drive reducer to drive track chain for machine traveling. Fully compatible with all mainstream brand excavators from 1T mini digger to 90T mining excavator.
Our Core Advantages:
1) Premium Alloy Raw Material Adopt 35Mn2 / 40MnB / 42CrMo high-strength forged alloy steel, high tensile & impact toughness, effectively avoid tooth crack & break under heavy load, rocky & muddy harsh working sites.
2）Dual Heat Treatment Craft Overall quenching & tempering + tooth surface medium-frequency induction hardening. Surface hardness HRC 50–62, hardening depth 8–12mm. Balanced hard surface & tough core, outstanding abrasion resistance, service life 30% longer than ordinary sprockets.
3）1:1 OEM Precision Machining CNC full machining for tooth profile, pitch circle, inner spline, bolt hole circle. Strictly copy OEM drawing parameters, perfect meshing with original track chain, no track slipping, no abnormal vibration & noise, protect final drive from overload damage.
4) Two Structural Options Available
One-piece solid sprocket: Low cost, widely used for mini & medium excavators;
Split segmented rim sprocket: Only replace worn tooth ring, save maintenance cost for large mining machines;
5）Full Model Coverage & Customization Complete part numbers for CAT, Komatsu, Hitachi, VOLVO,Kobelco, Doosan, Hyundai, Sany, XCMG, Case, Kubota, JCB, Liebherr. Support ODM/OEM: Custom size, tooth count, painting color, logo marking per drawings & samples.
