This 130201000038 SY215 lower track roller is a leak-proof chassis load-bearing component optimized for medium-sized excavators working long uninterrupted shifts on construction sites. Designed to address the common oil leakage issues of standard single-seal track rollers under continuous vibration, this bottom roller features an upgraded reinforced double floating seal assembly. The dual independent sealing system effectively locks internal lubricating oil while blocking mud, sand, and sewage from invading the inner shaft cavity. It maintains stable sealing performance during 24-hour non-stop site operation, significantly reducing roller failure, unexpected downtime, and maintenance costs for SY215 series excavator undercarriage systems.

Most ordinary aftermarket track rollers only equip a single floating seal ring. Under long-term track vibration, high operating temperatures, and muddy working environments, single seals are prone to aging, deformation, and gap leakage, leading to lubricant loss, shaft dry friction, roller jamming, and premature failure. Our 130201000038 track roller is built with a matched double floating seal structure featuring dual protection layers. Every finished roller undergoes full air tightness pressure testing before delivery to simulate actual continuous working pressure. This strict sealing inspection eliminates unqualified products with hidden leak risks, effectively solving oil leakage issues for round-the-clock site construction.
- Reinforced Double Floating Seal System: Dual-layer sealing shares vibration pressure and high-temperature erosion, avoiding oil leakage caused by single seal fatigue failure during continuous operation.
- Excellent Anti-pollution Performance: Double barrier stops mud, water, and fine dust from entering internal rotating parts, protecting bearings and shafts from corrosion and abrasive wear.
- Longer Service Life With Stable Lubrication: Permanent internal oil storage keeps smooth rotation at all times, reducing roller breakdown rate and maintenance frequency.
- Perfect Direct Replacement Size: Strictly manufactured per standard part dimensions, requiring no modification during on-site undercarriage replacement to save repair time.
This double floating seal anti-leakage track roller is specifically designed for SY215 series excavator continuous site operation and undercarriage routine replacement. All rollers pass individual leakage inspection before packaging, with anti-rust oil coating, waterproof film wrapping, and impact-resistant wooden box packaging for long-distance sea freight. We support air tightness test reports, sample orders, and bulk wholesale, providing low-maintenance, oil-leak-free chassis spare parts for global construction equipment maintenance merchants and fleet owners.
