Road Roller Parts

SANY  Road Roller Parts

Sany roller components constitute an original equipment manufacturer (OEM) parts system developed by Sany Heavy Industry, leveraging core technologies in road machinery and global manufacturing capabilities. This system delivers efficient, durable component solutions for comprehensive compaction operations across high-grade highways, airports, mines, and other scenarios. Covering critical systems including power transmission, hydraulics, vibration, and undercarriage, these parts are compatible with the full range of models, including the SSR series single-drum and SR series double-drum rollers. Through technological innovation, they also achieve compatibility and substitution for equipment from international brands.

Core Technology and Product Advantages:

• Key components developed in-house and manufactured through global supply chain collaboration—such as planetary gearboxes—incorporate Schaeffler bearings and proprietary alloy steel treated with carburizing and quenching processes. This achieves industry-leading gear precision and load-bearing capacity. Hydraulic system components (e.g., high-pressure cylinders) are developed in deep collaboration with Rexroth, delivering response times ≤3ms and over 10% increased operating pressure. Vibratory wheels employ oil-cup lubrication technology, tested through 100,000 load cycles with a comprehensive lifespan exceeding 10,000 hours, accommodating multi-frequency compaction demands from 27-32Hz.
• The integrated intelligent compaction system employs high-precision positioning, temperature sensors, and a big data cloud platform to monitor compaction density, pass count, temperature, and other parameters in real time. It generates visual color-graded maps to guide operations, significantly enhancing construction uniformity and quality. For instance, on a Nanjing expressway project, sections using Sany’s intelligent compaction technology achieved 20% lower compaction density variability and 15% improved structural depth uniformity compared to traditional methods. The C10+ series launched in 2025 further upgrades the intelligent core, supporting unmanned cluster operations with compaction accuracy reaching ±0.25%, achieving internationally leading standards.
• Stringent Quality Control and Weather Resistance All genuine components undergo multidimensional testing: material composition analysis, extreme temperature validation (-40°C to 120°C), and 30% slope operation simulation, complying with national standards like GB/T 25684.13-2021. For instance, spray nozzles utilize 304 stainless steel with micro-pore arrangements ensuring uniform atomization. Paired with a multi-layer water filtration system, they intercept over 99% of impurities, significantly reducing nozzle clogging risks. Chassis components like the 350mm large-pitch tracks (China’s largest) employ Hardox wear-resistant steel, delivering over 15,000 hours of service life in rocky conditions.
