The chain coupling consists of a shaft coupling assembled from 2 rows of roller chain and 2 sprockets which engage them.
By freely inserting or removing a joint pin, the chain ends can be simply connected or dismantled.
The original KANA structure is such that the case has been split into two perpendicularly to the shaft, and the cases KC3012 to KC8022 have a V-shaped groove on both sides with an O-ring inserted to prevent oil leaks.
