Roller bearings aren't necessarily superior to sleeve bearings. Harley Davidson used roller bearings for years, and Honda Gold Wings used sleeve bearings. Which is more reliable? Those diesel engines with multi-hundred thousand miles use sleeve bearings. Your lawn mower uses roller bearings. Which lasts longer?
