What are the reasons for the aging of the reducer skeleton oil seal? 2026-04-21
The main reasons for the aging of the reducer skeleton oil seal include material deterioration, high temperature environment, poor lubrication, shaft surface wear, improper installation, and the intrusion of impurities in the working environment. These factors will act alone or together, causing the oil seal to lose elasticity, crack the lip, reduce sealing performance, and eventually cause oil leakage failure. 1. Natural aging of materials and chemical incompatibilitySkeleton oil seals are mostly made of elastomeric materials such as nitrile rubber (NBR) and fluorine rubber (FKM). After long-term use, natural aging occurs due to oxidation, thermal degradation and other reasons, which is manifested by the rubber becoming hard, cracking, and losing elasticity. If the lubricating oil contains amine additives, it may react chemically with the fluorine element in the fluorine rubber, causing the oil seal material to harden and crack. The use of oil seal materials that are incompatible with the working medium (such as nitrile rubber used in high temperatures or corrosive environments) will also accelerate aging. 2. High temperature environment accelerates aging Long-term operation under high temperature conditions (such as excessive
