PURPOSE:To provide a plastic-coated bearing outstanding in both heat resistance and durability, giving high lubricating effect even at high temperatures and high vacuum, with its sliding surface represented by an organic coating film containing specific fluorine-contg. bound group in the molecular chain. CONSTITUTION:The objective bearing with its sliding surface represented by an organic coating film containing in the molecular chain fluorine-contg. bound group of formula I or II (Rf is fluorine-contg. poly-oxyalkyl; R2 is 2-3C oxyalkylene or subsituted oxyalkylene; R' is H, -CH3 or of formula III; m is integer >=1) (pref. amino group-terminated polyimide coating film on the surface of which fluorine-based compound has been chemically fixed). |
