CAT 300*52.5N*86 rubber track

This rubber track (specification: 300 × 52.5N × 86) is a common undercarriage component for small-to-medium-sized excavators. The "N" designation indicates a specialized anti-derailment design (Narrow/Non-tracking) or a specific guide lug pitch profile. Renowned for its excellent off-road mobility and superior tensile strength, this model is widely used on various compact and medium-sized excavators, ensuring stable operation in challenging working conditions. **Technical Specifications** **Specification Breakdown:** **Width:** 300 mm **Pitch:** 52.5 mm **Number of Links:** 86 **Model Features:** Optimized for frequent turning operations; the anti-derailment guide lug design significantly reduces the risk of the track slipping off when working on slopes or muddy terrain. **Base Material:** Formulated from a blend of high-density natural and synthetic rubber, offering exceptional resistance to wear, tearing, and degradation caused by abrasion or chemical exposure (acids/alkalis). **Internal Structure:** **High-Strength Steel Cord Layers:** Manufactured using continuous, jointless winding technology, which greatly enhances the track's overall tensile strength and prevents stretching or breakage during frequent, heavy-load turning. **Precision-Cast Core Irons:** The core iron structure is optimized for precise meshing with the equipment's drive sprocket, effectively minimizing vibration during power transmission and extending the service life of drive sprockets and travel motors. **Tread Pattern:** Features an asymmetric, deep-traction tread design that delivers superior grip and self-cleaning capabilities, preventing excessive mud buildup between the lugs. **About Us** Guangzhou Jianming Machinery Equipment Co., Ltd. is an expert in the field of mechanical power systems and components, backed by 20 years of solid practical experience.
