Babban juriya na zafin jiki - zafin aiki zai iya kaiwa 250 ° C.
Low zafin jiki juriya - yana da kyau inji taurin;ko da zafin jiki ya ragu zuwa -196 ° C, zai iya kula da tsawo na 5%.
Juriya na lalata - rashin ƙarfi ga yawancin sinadarai da kaushi, mai jurewa ga acid mai ƙarfi da alkalis, ruwa da sauran kaushi na halitta.
Jure yanayin yanayi - yana da mafi kyawun rayuwar tsufa tsakanin robobi.
High lubrication - mafi ƙasƙanci coefficient na gogayya tsakanin m kayan.
