Which of the following is not a characteristic of a P/M bearing material?

Which of the following is not a characteristic of a P/M bearing material? Correct Answer Short service life

The important requirements of a P/M bearing materials are: good lubrication characteristics with minimum maintenance and long service life, adequate mechanical strength, good wear characteristics, good heat dissipation capacity, ability to withstand both static and impact loads, and must not weld/seize with the mating parts (e.g. shafts) during service.
