SF-1S


Properties

SF-1S sliding bushings are oil-resistant, acid-resistant, alkali-resistant and salt-water-resistant.

Furthermore, the PTFE surface sliding layer is lead-free, meaning that this type of bushing can be used for applications in the food industry, for alkali-flow measuring devices, in pharmaceutical machinery, printing machinery, in chemical engineering and in the shipping industry.
