The Hot Sale Jonyang JY-230E Excavator Chain Sprocket is a precision-engineered drive component designed specifically for the Jonyang JY-230E 23-ton tracked hydraulic excavator. As the critical power transmission element of the undercarriage system, the chain sprocket (also known as the drive sprocket or track sprocket) engages directly with the track chain bushings to transfer torque from the travel motor to propel the excavator forward and backward. This sprocket ensures smooth, efficient movement across construction sites, mining operations, and earthmoving projects.

Manufactured from high-grade 50Mn or 40MnB alloy steel through precision forging and CNC machining 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 52-58 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 to match the JY-230E’s undercarriage specifications—including a 600mm track shoe width, 2400mm track gauge, and 4510mm total track length—this sprocket guarantees OEM-spec fitment. The precision-machined mounting holes ensure accurate bolt fit and stable installation. An anti-corrosion coating provides rust resistance in wet or abrasive environments.

Jonyang, established in 1936 with over 50 years of engineering machinery manufacturing expertise, produces the JY-230E with internationally renowned components including Cummins engines and advanced hydraulic systems. This sprocket is the dependable choice for operators seeking consistent, top-tier performance from their Jonyang excavators.
