Nylocs working range is up to about 120C IIRC. Use some Loctite Nutlock as well if you want some extra confidence; that has a working temperature that goes up to 150ish C. As Ruairidh says, there must be hundreds if not thousands of motors built with Nyloc nuts retaining big end caps which are still running without issues.
Finding Binx, Philedas, Aerotight, Dotloc or Stenor all metal locknuts in BSF sizes now is likely to be a mission, as they are pretty well certain to be old stock that's been sitting on a shelf somewhere for several decades.
