Rubber tracks sized 320x86x52 indicate a track with a total length of 320 mm, width of 86 mm, and a pitch of 52 mm — the distance between track cleat centers. This sizing defines compatibility with mini machinery undercarriages and is crucial to select precisely for optimum performance.
What Does Each Number in 320x86x52 Rubber Track Size Mean?
The size 320x86x52 breaks down as follows:
-
320 mm: Track length measured along the inside of the track where contact occurs.
-
86 mm: Track width, influencing ground contact area and flotation.
-
52 mm: Track pitch, which is the distance between adjacent track lugs or links measured from center to center.
This combination ensures matching sprocket engagement and proper machine fit.
How Does Track Pitch Affect Rubber Track Compatibility?
Track pitch controls the fit between track lugs and sprocket teeth. A pitch mismatch causes drive slippage, accelerated wear, and damage to the undercarriage.
A 52 mm pitch means the sprocket teeth spacing and track link spacing must both be 52 mm for smooth operation.
Which Machinery Commonly Uses 320x86x52 Rubber Tracks?
Rubber tracks of this size typically fit mini excavators, compact skid steers, and small track loaders designed for tight spaces and delicate terrain. Brands like Kubota, Komatsu, and Caterpillar manufacture equipment compatible with these track dimensions.
Using the correct size ensures machine efficiency and safety.
Why Is Correct Track Width Important in Selection?
Track width affects flotation and surface impact. An 86 mm width provides adequate ground contact, balancing between stability and minimal soil disturbance. Too narrow causes excessive ground pressure, while too wide may affect machine clearance.
Selecting correct width extends track life and protects job sites.
How Is Track Length Measured and Why Is It Important?
Track length is measured along the track’s inside surface that contacts undercarriage parts. A length of 320 mm indicates the internal circumference suited for the machine’s rollers and sprocket.
Proper length ensures tension accuracy and prevents derailing or slippage.
| Dimension | Measurement | Purpose |
|---|---|---|
| Track Length | 320 mm | Fits the undercarriage circumference accurately |
| Track Width | 86 mm | Determines ground contact and machine footprint |
| Track Pitch | 52 mm | Matches sprocket teeth spacing for power transfer |
When Should Rubber Tracks Like 320x86x52 Be Replaced?
Visual damage, cracks, missing lugs, oversized stretch, or frequent slippage indicate replacement needs. Worn tracks affect machine safety and productivity, so timely replacement with correct size is critical.
Inspect tracks regularly and replace proactively to avoid breakdowns.
