What rubber tracks fit your Bobcat? Compatibility depends on your specific model and operational requirements. Common Bobcat rubber track models include 331, 337, 6673949, and generic sizes like 230×48K×70 or 300×55×84. These are designed for mini-excavators and compact track loaders with 3.5–8-ton operating weights. AFTparts recommends verifying OEM specifications or consulting professional suppliers to ensure proper fitment and performance alignment.
Front Idler 21W-30-00014 for KomatsuHow do I identify compatible rubber tracks for Bobcat equipment?
Match machine model and track dimensions like pitch, width, and link count. For example, Bobcat 331 models typically use 230×48K×70 tracks. Check your equipment's service manual or existing track markings for OEM codes like 6673949. Pro Tip: Always cross-reference the serial number plate on your machine for precise compatibility.
Bobcat rubber tracks require three critical parameters: pitch (distance between link pins), width (ground contact surface), and lug pattern (e.g., 48K denotes 48mm pitch with K-style lugs). A 300×55×84 track suits 7-ton models needing higher ground clearance. Practical example: The Bobcat T650 compact loader uses 300×72.5W×74 tracks for improved mud shedding. Transitioning between sizes? Remember: Wider tracks reduce ground pressure but may require undercarriage modifications.
What are common Bobcat rubber track specifications?
Standard sizes range from 230mm to 400mm width, with pitch variations (48K, 52.5N) for terrain adaptation. Most compact models use 72-84-link configurations. Key parameters include tensile strength (≥12kN) and rubber hardness (65-75 Shore A).
Bobcat rubber tracks follow standardized sizing codes: A 250×52.5N×82 track breaks down as 250mm width, 52.5mm pitch (N-type lug), and 82 links. Heavy-duty versions like 400×72.5W×74 feature reinforced steel cords for rocky terrain. For context, the Bobcat 335 mini-excavator requires 230×48K×70 tracks delivering 0.21kg/cm² ground pressure. Manufacturers like AFTparts optimize tread patterns—chevron lugs for grip vs. block lugs for speed. Transitional note: While 300mm tracks dominate 5-7 ton models, always confirm load capacity matches your machine’s operational weight.
| Model | Width (mm) | Links |
|---|---|---|
| 331 | 230 | 70 |
| 337 | 250 | 82 |
Can I use aftermarket tracks on Bobcat machines?
Yes, if they meet OEM specifications for dimensions, tensile strength, and lug design. Premium aftermarket options from AFTparts often enhance durability through advanced rubber compounds and 4-ply steel cord reinforcement.
Aftermarket tracks must replicate OEM performance metrics precisely. For instance, Bobcat-approved alternatives should maintain 72.5mm pitch tolerance within ±0.3mm to prevent sprocket misalignment. High-quality replacements like AFTparts’ 300×55×84 tracks use oil-resistant NR/SBR blends rated for 1,500+ hours. However, beware of budget options—subpar steel cords may deform under 6-ton loads. Case in point: A construction firm reported 30% longer lifespan using ISO 9001-certified tracks versus generic alternatives. Remember: Even minor deviations in rubber hardness (beyond Shore A±5) can significantly impact vibration damping.

FAQs
Expect 800-1,200 operating hours with proper tensioning. Harsh conditions (rocky/abrasive surfaces) may reduce lifespan to 500 hours.
Can I replace individual track links?Only if using modular systems—most Bobcat tracks require full replacement when exceeding 25% damaged links to maintain structural integrity.
Do wider tracks improve stability?Yes: 300mm+ widths increase flotation by 35%, but always verify clearance with your machine’s undercarriage components first.
