Hebei Hankai cassette oil seal


The design must be such that it balances the need for a tight seal with the amount of friction generated during operation. Excessive friction can lead to wear and heat buildup, while insufficient sealing can allow fluid leakage. Therefore, engineers carefully select materials and dimensions to ensure optimal performance.

1. Energy Efficiency One of the primary advantages of installing weather seals is improved energy efficiency. By sealing gaps around the door, we can significantly reduce heat transfer between the indoors and outdoors. In winter, weather seals prevent warm air from escaping, thereby lowering heating costs. Conversely, during the summer, they help keep cool air inside, reducing the demand for air conditioning. This not only translates to lower utility bills but also contributes to a reduced carbon footprint.
