The High Strength EX360 Excavator Undercarriage Sprocket (also known as drive sprocket or track sprocket) is a precision-engineered power transmission component designed specifically for Hitachi EX360 series 36-ton class excavators. As the critical drive element of the undercarriage system, the sprocket engages directly with the track chain bushings to transfer torque from the travel motor, propelling the excavator forward and backward across construction sites, mining operations, and heavy earthmoving projects.

Manufactured from high-grade 50Mn alloy steel through precision forging and casting processes, this sprocket delivers exceptional structural integrity and impact resistance. The sprocket teeth undergo full-surface induction hardening and heat treatment, achieving a surface hardness of HRC 50-56 with a hardening depth of 8-12mm. This deep, uniform hardened layer ensures long-lasting engagement with the track chain under heavy load conditions and provides wear resistance that maximizes service life.

Engineered for the Hitachi EX360 series—featuring a 36-ton operating weight and robust traditional diesel power system—this sprocket guarantees OEM-spec fitment and dependable performance. The precision-machined tooth profile ensures accurate engagement with the track chain, helping reduce premature wear while extending the service life of key undercarriage components. An anti-corrosion protective coating provides rust resistance in wet or abrasive environments. Available in black or yellow finish
