CAT 400*72.5N*74 Rubber Track

This rubber track (specification: 400 × 72.5N × 74) represents a well-proven undercarriage configuration for medium-sized construction machinery. Its "N-series" guide lug design optimizes the contact interface between the track, track rollers, and idlers; this significantly enhances stability on rugged terrain and during frequent slewing operations, effectively preventing the track from derailing under harsh working conditions. **Product Technical Specifications** **Specification Breakdown:** **Width:** 400 mm **Pitch:** 72.5 mm **Number of Links:** 74 **Design Features:** N-Series (anti-derailment design); optimized geometry for drive lugs and guide lugs ensures smoother operation of the travel system and reduces wear caused by lateral forces. **Base Material:** High-grade, wear-resistant natural rubber composite formula; offers excellent cut and puncture resistance, maintaining high-performance capabilities on gravel surfaces and amidst construction debris. **Internal Structure:** **Jointless Steel Wire Winding Technology:** Incorporates multiple layers of high-strength steel wire reinforcement, eliminating weak points at the joint and fundamentally solving the issue of track breakage during heavy-load turning. **Forged Core Iron Structure:** Precision-cast, robust core irons effectively increase the contact area with the drive sprocket; this ensures efficient power transmission while significantly extending the service life of travel motors and the undercarriage wheel system. **Tread Pattern:** Deep-traction tread design ensures superior grip on wet clay or loose gravel surfaces; features excellent self-cleaning capabilities to minimize mud and debris accumulation. **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.
