Utilizing the excellent mechanical properties and weather resistance of nylon, it can manufacture window frame cushioning, door pulleys, curtain rail pulleys, etc.; using nylon wear resistance and self-lubricating properties, it is used to manufacture automatic door rails and lift parts.
research shows. Its UV resistance, withstandable radial load of 25t, wear life is 3-5 times that of steel pulleys. Its good self-lubricating and elastic properties greatly improve the service life of other parts in the door.
