This amorphous polymer is commonly used for its high shock resistance even at low temperature. It is not a material recommended for mechanical applications, even if its dimensional stability does make it suitable for precision parts.
It has no self-lubricating power and it is attacked by oil and grease, therefore it cannot be considered suitable for lubricated moving mechanical parts.
From the bar graph we can see that the materials with higher operating temperatures are: PES - PEI - PEEK
