  • manufacture works with a high degree of accuracy
  • categorized into gear pair with parallel axes when classifying in relation to arrangement of gear shaft
  • tooth trace is straight and parallel to shaft, and distinguished from helical gear which is also cylindrical gear but whose tooth trace is helix
  • does not generate thrust force toward shaft direction when rotating
  • generates larger noise than helical gear
