Rubber tracks directly influence machine stability, ground disturbance, and undercarriage component life. This aftermarket rubber track-excavator 450*81.5*76 sk85 is vulcanised to OEM pitch, lug height, and width dimensions for correct engagement on the 450*81.5*76 drive sprocket and idler — no track tension adjustment issues on install.

Why Choose This Rubber Track-Excavator 450*81.5*76 Sk85
– Lug height maintained to OEM dimension for positive sprocket tooth engagement without sprocket skipping
– Track pitch matches OEM sprocket tooth spacing — no shimming of idler position required
– Full-width profile preserves OEM ground contact area and rated ground pressure

Heavy-Duty Construction
This rubber track-excavator 450*81.5*76 sk85 is manufactured using high-tensile steel cord core: resists elongation under pull loads and maintains pitch under tension. Natural/synthetic rubber blend with carbon-black reinforcement for cut and tear resistance. Steel guide lugs: hardened to resist side-loading wear from turns and lateral ground forces. Designed to withstand vibration, impact loads, and harsh operating environments commonly found in construction, quarry, mining, and earthmoving applications. Precision manufacturing helps ensure correct fitment and long service life.

Applications
Suitable for a wide range of heavy equipment and undercarriage systems including:
– Excavators
– Dozers
– Loaders
– Track roller assemblies
– Earthmoving machinery undercarriage components

Maintenance Recommendations
– Set track tension to OEM sag specification — overtension accelerates cord fatigue
– Avoid prolonged operation on sharp rock without steel core tracks
– Inspect guide lugs for chunking every 250 hrs; early detection prevents derailment
