Excavator and Bulldozer Undercarriage Sprockets and Segments
Sprockets are essential parts of most crawler equipment, including excavators, dozers, cranes, drilling machines, and more. Proper undercarriage maintenance significantly lessens the chance for a larger breakdown in the middle of an important job. Sprockets and segments work with the undercarriage track to drive track-style equipment movement. If your sprockets and segments show wear, chances are that you will need to look into replacement parts.
Sprockets Vs. Segments
Sprockets are metal gears with an inner ring that has bolt holes or a compression hub and gear ring all within a single unit. In contrast, segments are individual pieces that can be linked together to form a metal ring. This means segments can be combined to create the effect of a complete sprocket, but are able to be individually replaced without dismantling the entire track.
Sprockets & Segments – CZPT or OEM Parts
Heavy machinery undercarriages help to carry tons of weight and propel movement. If your undercarriage experiences significant use, it will likely need repair and replacement parts. Original equipment manufacturer (OEM) parts are produced at the same factory that makes the equipment they are used for. Purchasing an OEM part ensures that the part will be identical to the part initially included in the vehicle at purchase. One might think these are the only high-quality replacement options, but CZPT part manufacturers provide replacement parts at a much lower price without sacrificing the machine match or quality.
Heavy Equipment Undercarriage parts
Quality heavy machinery undercarriage parts help prevent premature wear on excavators, dozers, track loaders, skid steers, and forestry equipment. The majority of maintenance and part costs for track-type equipment is from its undercarriage. That means, selecting high-quality parts is essential to keeping your machines running efficiently and to save costs.

Track Adjusters – Vochains offers track adjusters that can directly replace your existing parts with a quick replacement. Track adjusters help to absorb shock and protect your machine from leakage while minimizing the risk of releasing the spring.
Track Chains – Vochains’ track chains are available in different versions to match your machine and environment. With track chains designed for easy installation, you can save time and money while increasing the performance of your machine.
Rollers – Vochains supplies track rollers are designed for a long wear life and strong performance even in the most extreme operating conditions. Increase the undercarriage clearance height to reduce the load on the front wheel, sprocket, and final drive. Top, bottom, and carrier rollers can decrease the weight on costlier parts, increasing overall wear life. By investing in quality rollers, you can save costs in the long run.
Pins & Bushings – Pins and bushings form the hinges that allow the links of the track chain to move around the sprockets & idlers. As pins and bushings naturally wear it primarily occurs on a single side of the pin and the matching surface of the bushing, which allows the track pitch to extend, causing a stretched chain that runs loose. Maintaining proper pins and bushings will keep your undercarriage tracks running effectively.
Routine Undercarriage Maintenance
When inspecting your equipment’s undercarriage, you are looking to see that everything is in its correct place and working properly.
This includes things such as:
Maintaining proper track tension.
Both loose and tight tracks can cause issues preventing your machine from functioning properly.
Using appropriate track shoes for different job sites.
Depending on the type of movement your machinery will be doing and the terrains you’ll be working in, choose track shoes that work well.
Signs of significant wear on the idlers.
Notable tread will appear as deep pockets or grooves across the surface of the idler.
You also want to ensure that a lip has not formed on the edge of the idler. If so, this lip indicates that it may be time for servicing.
Keeping your undercarriage clean and well-lubricated.
Build-up of dust, mud, and debris can impact lubrication and make your equipment more difficult to use, which may cause operators to be a bit rougher when forcing it to maneuver or operate.
Inspecting frequently.
Frequent and thorough inspections, preferably with an operator’s manual in hand, can help operators spot wear, damage, and other issues before they get out of hand and result in more significant repair costs.
These visual inspections should occur daily.

Can I replace worn-out idler sprockets, or do they need to be replaced with the entire system?
In most cases, worn-out idler sprockets can be replaced individually without replacing the entire conveyor system. Idler sprockets are separate components that can be easily removed and replaced when they show signs of wear or damage. However, it’s essential to assess the condition of the idler sprockets and their compatibility with the existing conveyor system before replacement.
If you notice excessive wear, chipping, or deformation on the idler sprockets during routine inspections, it’s an indication that they need replacement. Replacing worn-out idler sprockets in a timely manner can prevent further damage to the conveyor chain and ensure the smooth operation of the system.
Before replacing idler sprockets, consider the following:
- 1. Compatibility: Ensure that the new idler sprockets are compatible with the existing conveyor system. They should have the same pitch, number of teeth, and dimensions to ensure proper engagement with the chain.
- 2. Quality: Use high-quality replacement sprockets made from durable materials to withstand the rigors of the application and provide long-lasting performance.
- 3. Inspection: Take this opportunity to inspect the entire conveyor system, including the chain and other sprockets. Replace any additional components that show signs of wear or damage.
- 4. Alignment and Tensioning: After replacing the idler sprockets, recheck the alignment and tension of the conveyor chain to ensure it operates smoothly.
Regular maintenance and prompt replacement of worn-out idler sprockets are essential to keep the conveyor system running efficiently and to extend its lifespan.
How do I prevent chain or belt slippage and skipping issues with idler sprockets?
To prevent chain or belt slippage and skipping issues with idler sprockets, it’s important to follow these best practices:
- Proper Tension: Ensure that the chain or belt is tensioned correctly. Insufficient tension can lead to slippage, while excessive tension can cause premature wear on the sprockets and other components.
- Quality Sprockets: Use high-quality idler sprockets that are designed for the specific application. Cheap or poorly-made sprockets may have inconsistent tooth profiles, leading to slippage issues.
- Correct Alignment: Properly align the idler sprockets with the driver and driven sprockets. Misalignment can cause the chain or belt to ride up on the teeth, resulting in slippage.
- Regular Inspection: Regularly inspect the sprockets and chain or belt for signs of wear or damage. Replace any worn-out components promptly to prevent slippage and further damage.
- Lubrication: Ensure that the chain or belt is adequately lubricated to reduce friction and minimize the chances of slippage.
- Clean Environment: Keep the conveyor or power transmission system clean and free from debris, as foreign particles can interfere with the sprocket-to-chain/belt engagement, leading to slippage.
- Correct Chain or Belt Selection: Choose the appropriate type and size of chain or belt for the application. Using the wrong type can result in compatibility issues and slippage.
By following these guidelines, you can help prevent chain or belt slippage and skipping issues with idler sprockets, ensuring smooth and efficient operation in your power transmission or conveyor system.
What are the different types of idler sprockets used in various applications?
Idler sprockets come in various designs and configurations to suit different applications and power transmission systems. Some of the common types of idler sprockets include:
- Plain Bore Idler Sprockets: These sprockets have a simple bore without any additional features. They are often used in applications where the idler sprocket is mounted on a stationary shaft.
- Ball Bearing Idler Sprockets: These sprockets are equipped with ball bearings to reduce friction and allow smoother rotation. They are suitable for applications where the idler sprocket needs to move or rotate.
- Needle Bearing Idler Sprockets: Similar to ball bearing idler sprockets, needle bearing idler sprockets use needle bearings for reduced friction and enhanced performance in high-speed applications.
- Tensioner Idler Sprockets: Tensioner idler sprockets are designed to automatically adjust the tension in the chain or belt. They are commonly used in automotive timing systems and other applications where tension control is critical.
- Flanged Idler Sprockets: These sprockets have flanges on either side to prevent the chain or belt from derailing. They provide extra guidance and stability, making them ideal for applications with high lateral forces.
- V-Groove Idler Sprockets: V-groove idler sprockets have a V-shaped groove to accommodate V-belts, allowing for better traction and reduced slippage in certain belt drive systems.
- Spring-Loaded Idler Sprockets: These sprockets have a built-in spring mechanism that applies tension to the chain or belt. They are commonly used in applications where tension needs to be maintained despite variations in load or temperature.
- Adjustable Idler Sprockets: As the name suggests, these sprockets offer adjustability to fine-tune the tension in the chain or belt. They are useful in applications where tension requirements may change over time.
The choice of idler sprocket depends on the specific requirements of the application, such as load, speed, space constraints, and environmental factors. Proper selection and installation of the right type of idler sprocket are essential for ensuring smooth power transmission and extending the life of the chain or belt.
