TY9103 Double Lip Seal Ring used for fan HU25040
Product Overview
The TY9103 Double Lip Seal Ring is a critical, high-wear core spare part specifically engineered for the harsh operating conditions of power plant Induced Draft (ID) Fans (high speed, high temperature, and heavy dust). Manufactured to exact original design specifications, this product perfectly fits mainstream ID fan models such as the HU25040-111G and HU25240-22G. Its primary purpose is to address the common industry pain points of traditional seals: rapid wear, short lifespan, subsequent lubrication oil leakage, and premature bearing failure.
Key Features & Advantages
-
Superior Sealing Performance: Features an innovative Double-Lip (Dual-Barrier) structure. The main sealing lips form multiple barriers, effectively isolating external dust and contaminants while preventing internal lubricating grease leakage. This ensures the bearing chamber remains clean and well-lubricated.
-
Excellent Material Resistance: Combines outstanding high-temperature resistance, oil resistance, and anti-wear capability. It is robustly designed to withstand the thermal stress and chemical corrosion prevalent around the ID fan's bearing housing.
-
Optimized Service Life: Precision mold design and manufacturing ensure a perfect fit between the sealing lips and the shaft journal. This results in low friction, minimal wear rate, significantly extending the seal's service life, and reducing forced shutdown frequency.
-
Simplified Replacement & Maintenance: High dimensional accuracy ensures the best interference fit with standard shaft journals and bores. It is easy to install and allows for rapid replacement during scheduled power plant maintenance outages, dramatically boosting maintenance efficiency.
