Rubber tracks sized 320x86Nx50 are widely used on compact track loaders and mid-sized excavators. The designation indicates 320 mm width, 86 mm pitch, N-type drive lug configuration, and 50 links. These specifications ensure proper fit, efficient power transfer, and stable operation. Choosing high-quality options from AFT Parts helps maximize durability, minimize downtime, and maintain consistent performance across demanding jobsite conditions.(Edited on June 10 2026)
What Do the Dimensions 320x86Nx50 Represent?
The size 320x86Nx50 follows a standardized rubber track measurement format used across the industry:
-
320: Track width in millimeters, defining ground contact and stability.
-
86: Pitch in millimeters, measuring the distance between drive lugs.
-
N: Drive lug configuration, indicating sprocket compatibility and roller path design.
-
50: Total number of links inside the track.
Correct interpretation of these dimensions is critical to ensure proper machine fitment and safe operation.
How Does Track Width Affect Performance?
Track width directly impacts flotation, traction, and ground pressure.
-
Wider tracks (320 mm) distribute machine weight more evenly, reducing soil compaction.
-
They improve stability, especially on soft or uneven terrain.
-
Narrower alternatives may increase ground pressure and reduce traction.
For compact loaders and excavators, 320 mm provides a balanced combination of maneuverability and surface protection.
Why Is Pitch and Link Count Important?
Pitch and link count determine how the track engages with the sprocket and undercarriage.
-
The 86 mm pitch must align precisely with sprocket teeth spacing.
-
The 50-link count ensures the correct overall track length and tension.
-
The “N” configuration defines internal lug shape and alignment with rollers.
Incorrect pitch or link count can lead to vibration, derailment, and premature wear. AFT Parts manufactures tracks with strict tolerances to ensure seamless engagement and long service life.

Example Compatibility Overview
Always verify specifications before purchasing, as undercarriage variations may exist within the same model series.
How Can You Verify Track Compatibility?
To confirm fitment, follow these steps:
-
Measure track width in millimeters.
-
Measure pitch between drive lugs.
-
Count total number of links.
-
Identify drive lug type (such as “N”).
Matching all four parameters is essential. AFT Parts provides technical support and measurement guidance to help buyers avoid costly errors.
