Rubber tracks sized 450x86Qx52 indicate a track with an internal length of 450 mm, a width of 86 mm, and a pitch of 52 mm. The “Q” often designates a specific track design or tread style. These dimensions are critical to ensure proper fit and performance on compatible mini excavators or compact machinery.
What Do the Dimensions 450x86Qx52 Represent?
The breakdown is:
-
450 mm: The track length, measured along the inside surface that contacts undercarriage components.
-
86 mm: The track width, indicating the rubber band’s ground contact width.
-
52 mm: The track pitch, spacing between centers of adjacent track lugs, important for sprocket engagement.
-
Q: Typically a code for tread pattern or reinforcement style.
Correct interpretation ensures proper selection for machinery compatibility.
How Does Track Pitch Affect Rubber Track Compatibility and Performance?
Precision matching the 52 mm pitch with sprocket teeth is vital for smooth power transfer. Mismatched pitch causes slippage, accelerated wear, and potential damage to both track and drive sprocket components. Pitch selection must align exactly with the manufacturer’s specifications.
AFT Parts highlights pitch precision for reliable undercarriage function.
Which Types of Equipment Use 450x86Qx52 Rubber Tracks?
These rubber tracks fit compact excavators, mini skid steers, and similar machinery used in construction, landscaping, and agricultural applications requiring stable, low-impact traction and maneuverability in confined areas.
Brands such as Caterpillar (CAT), Komatsu, and Kubota commonly utilize tracks of this sizing.
Why Is Track Width Important for Machine Stability?
The 86 mm width strikes a balance between ground coverage for flotation and machine stability, versus the need for maneuverability in narrow or delicate areas. Wider tracks increase surface contact for better traction; narrower tracks reduce ground pressure in tight spaces.
Choosing appropriate width optimizes performance and reduces job site damage.
How Is Track Length Measured?
Track length is the inner circumference of the rubber track, defining the fit around the rollers, idlers, and sprockets. A 450 mm length ensures compatibility with the machine’s undercarriage configuration, essential to maintain track tension and prevent derailing.
Accurate measurement is crucial for operational reliability.
| Dimension | Measurement | Purpose |
|---|---|---|
| Track Length | 450 mm | Correct circumference for undercarriage fit |
| Track Width | 86 mm | Determines ground contact area and traction |
| Track Pitch | 52 mm | Matches sprocket teeth spacing for power transfer |
| Tread Pattern (Q) | Specific | Indicates tread design and material reinforcement |
When Should Rubber Tracks of This Size Be Replaced?
Replace tracks showing visible cracking, split lugs, steel cord exposure, or when loosening causes slippage. Timely replacement with exact size prevents secondary undercarriage damage and maintains machine safety and productivity.
Regular inspections optimize replacement timing.
