What are some more pros and cons.
High Torgue and moisture and long production runs is the type of operating environment.

    Generally speaking, if the distance between shafts is large, belt drive is preferred. However, it may vary according to application.

    Some disadvantages with chain drive-
    1. Lubrication is very important as unlubricated chains wear 300 times faster than the lubricated chains.
    2. The lubrication attracts dirt which leads to wear.
    3. Accurate alignment is required.
    4. Not suitable for vertical shaft drives.
    5. Noisy
