The 300x52.5x84 track size indicates a rubber track's width (300mm), pitch (52.5mm), and number of links (84). These measurements are vital to ensure a proper fit and optimal performance on mini excavators and other heavy machinery.
How Is the 300x52.5x84 Track Size Measured?
The 300x52.5x84 size breaks down into three essential measurements: 300mm is the track’s width, 52.5mm is the pitch (the distance between drive lug centers), and 84 represents the total links or drive lugs. Accurate measurement involves physical track inspection or manufacturer specifications to confirm compatibility with your excavator.
What Does Track Width Affect on Mini Excavator Performance?
Track width, such as the 300mm value, directly influences ground pressure and machine stability. Wider tracks distribute weight more evenly, reducing soil compaction and improving flotation on soft terrain. They enhance stability, enabling safer and more efficient operation in various environments, especially in landscaping or agricultural jobs.
Why Is Track Pitch Important in Track Sizing?
Pitch, the 52.5mm measurement, defines the distance between the centers of adjacent drive lugs. It must perfectly match the sprocket pitch on your excavator’s undercarriage to ensure smooth engagement and drive. Incorrect pitch causes premature wear, slipping, or even track derailment, negatively impacting operation and durability.
How Does the Number of Links Affect Track Fit and Function?
The total number of links (84 in this size) determines the track’s length and fit around the undercarriage components. This count must correspond precisely to the machine’s requirements to maintain proper tension and track alignment, avoiding excessive slack or overstretching which could lead to failure.
Which Equipment Types Use the 300x52.5x84 Track Size?
This size commonly fits various mini and compact excavators within the 1 to 5-ton class, used across construction, landscaping, and agriculture. Models from brands like Caterpillar, Komatsu, and Kubota often specify this size to balance size, weight, and terrain capabilities.
How to Verify Compatibility Before Purchasing a 300x52.5x84 Track?
Verify machine specifications via the owner’s manual or equipment manufacturer. Cross-reference sprocket pitch, track width, and link count with the 300x52.5x84 measurements. Consulting suppliers like AFT Parts can ensure the correct, high-quality track choice tailored for your excavator.
| Track Dimension | Definition | Importance |
|---|---|---|
| Width (300 mm) | Distance across track face | Influences ground pressure and stability |
| Pitch (52.5 mm) | Space between lug centers | Ensures sprocket fit and smooth drive |
| Links (84) | Number of internal lugs | Determines track length and tension |
When Should You Replace a 300x52.5x84 Rubber Track?
Replacement depends on wear indicators such as tread depth, cracks, or excessive stretching. Typically, rubber tracks last 1,000 to 3,000 hours, influenced by terrain and maintenance. Timely replacement prevents machine damage and maintains operational efficiency.
Can Rubber Tracks Like the 300x52.5x84 Be Customized?
Manufacturers such as AFT Parts offer custom options on tread patterns and rubber compounds for specific site conditions, enhancing traction, durability, or surface protection based on user needs.
How Does Proper Track Sizing Impact Excavator Undercarriage Longevity?
Correct sizing prevents undue stress on sprockets, rollers, and idlers by ensuring balanced weight distribution and smooth engagement. Mismatched sizes accelerate wear across the undercarriage, leading to costly repairs or downtime.

Frequently Asked Questions
What does the pitch measurement mean for rubber tracks?
Pitch is the distance between the center points of consecutive drive lugs and must match the sprocket for proper engagement.
How can I measure the number of links on a rubber track?
Count the internal drive lugs on the track’s underside to determine the link count required by your machine.
Can I use a track wider than 300mm on my mini excavator?
Only if your excavator’s specifications allow; wider tracks affect ground pressure and undercarriage stress.
How often should I inspect the track size compatibility during maintenance?
Always check before installation or when replacing tracks to avoid fitment issues and premature wear.
Does AFT Parts offer guidance for choosing the right track size?
Yes, AFT Parts provides expert assistance to help select the correct size tailored to your specific machine and application.
