The JCB JS200 excavator sprocket is a critical undercarriage component that transfers driving force from the final drive to the track chain. Designed for demanding construction, mining, quarrying, and earthmoving applications, this replacement sprocket helps maintain stable track movement and reliable crawler performance.

Manufactured from high-strength alloy steel, the sprocket is designed to withstand heavy loads, torque, impact, vibration, and abrasive working conditions. Precision machining helps ensure accurate tooth geometry and proper engagement with the track chain, while controlled heat treatment improves surface hardness and wear resistance.

The sprocket works together with the track chain, track rollers, front idler, and final drive to maintain efficient power transmission. Proper tooth engagement helps reduce abnormal track movement and unnecessary wear on the sprocket and track links. Replacing a worn sprocket at the right time can help maintain undercarriage efficiency and reduce maintenance costs.

Our JCB JS200 sprockets undergo strict quality control during production. We inspect tooth dimensions, mounting holes, machining accuracy, surface condition, and hardness to ensure consistent quality and reliable installation. Aftermarket sprockets can be supplied according to the machine model, track configuration, and OEM reference.

Multiple sprocket configurations are available for JCB JS200 applications. Industry parts listings identify several sprocket references for JS200, including LK120, JLA0177, JRA0113, and LK105V, depending on the machine version and undercarriage configuration.

This sprocket is suitable for replacement requirements in construction, quarrying, mining, and heavy earthmoving operations. Customers should confirm the machine version, serial number, track configuration, and OEM number before ordering.

We supply JCB excavator undercarriage parts for distributors, contractors, repair companies, and heavy equipment parts dealers.
