TOSOG Undercarriage Sprockets

Heavy-Duty Drive Sprockets for Excavators, Dozers & Track Machines

At TOSOG (The One Stop OEM Guy), we supply high-performance undercarriage sprockets designed and manufactured to deliver maximum torque transfer, extended wear life, and dependable traction in the most demanding construction, mining, quarrying, and earthmoving environments.

Our sprockets play a critical role in the drivetrain and undercarriage system by efficiently transferring power from the final drive to the track chain, ensuring smooth machine movement, optimal traction, and reduced drivetrain stress. Every sprocket supplied by TOSOG is engineered to meet or exceed OEM specifications, providing reliable engagement with track links while minimising slippage, vibration, and premature component wear.

We offer a comprehensive range of OEM, premium aftermarket, and heavy-duty reinforced sprockets, giving customers the flexibility to select the right solution based on machine age, operating conditions, workload intensity, and budget requirements. Whether you are operating in abrasive mining conditions, rocky quarry sites, soft sand, clay, or mixed terrain, TOSOG sprockets are built to withstand high torque loads, constant shock impact, and extreme working hours.

All TOSOG undercarriage sprockets are manufactured from high-grade alloy steel, precision-machined, and heat-treated for superior hardness and wear resistance. This ensures:

• Consistent tooth profile and accurate pitch

• Reduced risk of tooth breakage or hooking

• Longer service intervals

• Improved compatibility with standard and heavy-duty track chains

Our sprockets are suitable for a wide range of tracked machinery, including:

• Excavators

• Bulldozers

Whether you are maintaining a single machine or managing a large fleet, TOSOG provides dependable undercarriage sprocket solutions that reduce downtime, extend undercarriage life, and lower total cost of ownership.

What Is a Sprocket?

A sprocket (also called a drive sprocket) is a critical undercarriage component that transfers power from the final drive to the track chain. It engages with the track links, propelling the machine forward and backward.

A worn or poor-quality sprocket can cause:

• Premature track chain wear

• Loss of traction

• Final drive damage

• Increased fuel consumption

That’s why choosing the correct, hardened sprocket is essential for machine uptime.
