Product Features

1.Profile Machined to Match 190 mm Track Pitch

The Sprocket 800305388 tooth geometry is CNC-machined to engage the 190 mm pitch track chain without binding. This precision ensures even load distribution across the sprocket, preventing uneven tooth wear and reducing vibration transmitted to the final drive during high-torque travel. It eliminates premature chain jumping caused by mismatched sprocket engagement.

2.Induction Hardened Tooth Surface at HRC 50-58

The tooth surfaces undergo induction hardening to reach a hardness of HRC 50-58 with a case depth of 6-10 mm. This hardened layer resists abrasive wear from rock and gravel during continuous digging. The core remains tough, preventing tooth fracture when the track encounters extreme impact loads on rocky terrain.

3.High Strength Alloy Steel Casting for Impact Resistance

Manufactured from high-strength alloy steel, the sprocket body is cast to withstand heavy digging and tramming forces. It absorbs the shock loads transferred from the track chain, ensuring structural integrity under continuous 21-ton excavator operation. The casting process eliminates internal porosity, ensuring uniform mechanical properties.

4.Precision-Machined Mounting Interface for Direct Fit

The mounting hub and bolt holes are precision-machined to OEM specifications for the XE215C. This guarantees a direct, bolt-on replacement without the need for modifications. The precise fit prevents Sprocket 800305388 misalignment, extending both sprocket and track chain service life while reducing downtime during undercarriage maintenance.
