Hebei Hankai hydraulic piston oil seals

The primary function of the 20x35x7 oil seal is to prevent the escape of lubricants from one chamber to another, ensuring that machinery operates smoothly and efficiently
. By sealing the gaps between moving parts, the oil seal helps in minimizing friction and wear, contributing to the longevity of equipment. Moreover, preventing oil leakage is crucial for maintaining proper lubrication levels, thereby supporting optimal operational conditions and reducing potential breakdowns.The materials used in manufacturing hydraulic seals are also vital to their performance. Common materials include rubber compounds, polyurethane, and PTFE (Polytetrafluoroethylene). Each material offers different advantages and is selected based on the operating environment. For example, PTFE seals are highly resistant to chemicals and extreme temperatures, making them ideal for demanding applications.

Prof Maged Younes, Chair of EFSA’s expert Panel on Food Additives and Flavourings (FAF), said: “Taking into account all available scientific studies and data, the Panel concluded that titanium dioxide can no longer be considered safe as a food additive . A critical element in reaching this conclusion is that we could not exclude genotoxicity concerns after consumption of titanium dioxide particles. After oral ingestion, the absorption of titanium dioxide particles is low, however they can accumulate in the body”.
