The filling mechanism of PTFE is introduced. The possibility of using PTFE instead ofbirch in tail shaft sleeves as a bearing surface in ships is discussed. The main features ofmixtures of different filler proportions are tested and the best dosage of PTFE is chosenfor making abrasion-resistance tail shaft sleeves of ships.
