Determining the correct rubber track size for your machinery is straightforward when you understand the industry-standard formula used by manufacturers. Here’s how to measure:

• Width: The width of the rubber track measured in millimeters
• Pitch: The center-to-center distance between the steel links measured in millimeters
• Links: The total number of steel links embedded within

Understanding Rubber Track Types

There are two main types of rubber tracks used in modern construction equipment:

1. Metal Core Rubber Tracks

   Often referred to as metal-core tracks, these are used in mini skid steers, excavators, compact track loaders and others. They feature a rubber exterior reinforced with embedded steel links and continuously wrapped steel cables, providing enhanced durability and rigidity. 

2. Non-Metal Core Rubber Tracks

   Commonly found on Multi-Terrain Loaders from brands like ASV, CAT, and Terex, as well as agricultural tractors like the Cat Challenger, John Deere, and Case models. These tracks utilize rubber drive lugs, and the measuring process for these tracks is the same, though they are generally model-specific, minimizing the risk of interchangeability issues.

Example of a Common Track Size

A typical steel-core rubber track size is 450x86x55, which fits models such as the Bobcat T300 and T750 compact track loaders. Based on our formula:

• Width = 450mm
• Pitch = 86mm
• Links = 55

To calculate the total inner circumference of the track, simply multiply the pitch by the number of links:

Pitch x Links = Circumference

For example:

86mm x 55 = 4730mm

Measuring Your Metal Core Track

If you're unsure of the size of your metal-core track, you can measure it by taking the following steps:

• Measure the track width in inches or millimeters
• Measure the center-to-center distance between two drive links
• Count the total number of drive links

To convert millimeters to inches, divide by 25.4:

450mm ÷ 25.4 = 17.7 inches

Identifying Critical Track Dimensions

Another key factor for metal-core tracks is the guide rail dimensions, which include the inner and outer guide width and guide height. These measurements are typically specific to each manufacturer and are essential for ensuring proper fit and functionality. The correct guide rail dimensions are crucial to prevent issues such as the track jumping off the machine or causing premature undercarriage wear.

At Prowler Tracks, we stock metal-core tracks in various guide styles, often offering multiple variations of the same size to accommodate different OEM designs. For example, the 300×52.5×80 track fits multiple mini-excavator models, including the Bobcat 331, Case CX30C, and the Komatsu PC27MR-2. While these tracks share the same basic size, variations in wing guide height and width may exist, affecting their compatibility and performance.

The Importance of Accurate Sizing

While it’s relatively simple to determine the track size for your machine, it’s important not to assume that any spare track will fit your equipment. Purchasing a used or off-brand track can lead to performance issues, including poor track engagement, excessive wear on sprockets or rollers, or an uncomfortable ride. It’s essential to work with a trusted rubber track supplier who can provide accurate specifications to ensure the proper fit.
