Precision-machined surface on hydraulic cylinder piston rods that ensures reliable sealing against contaminants and fluid leakage.
The seal surface is a critical precision-ground or polished cylindrical area on a hydraulic piston rod where dynamic seals (such as rod seals, wipers, and scrapers) make contact. This surface must maintain specific roughness, hardness, and geometric tolerances to prevent fluid leakage, exclude contaminants, and ensure smooth rod movement under high pressure and varying temperatures. Its integrity directly affects cylinder efficiency, service life, and system reliability in industrial applications.

这些分值是采购评估维度示例，不代表真实客户评分、具体国家买家反馈或实时询盘。
Common causes include abrasive contamination (scratches), corrosion from harsh environments, improper surface finish (too rough or too smooth), insufficient hardness leading to wear, and misalignment causing uneven seal contact.
Inspect during routine maintenance every 6-12 months or per OEM guidelines. Check for scratches, pitting, corrosion, and measure surface roughness. Immediate inspection is needed if leakage or erratic movement occurs.
Minor damage can be polished out if within tolerance; severe damage requires re-grinding and re-plating or rod replacement. Always verify specifications post-repair to ensure compatibility with seals.
