RS25B
Sprocket Pitch : 6.35 mm
■When the ratio of revolutions between the two axes is absolutely
   accurate and must be transmitted over a long distance, the chain
   drive is most suitable.
■When there is only tight tension in the transmission, the tensio
  of the loose side is almost zero, the effective pulling force is large,
  and the transmission efficiency is high.
