* Bores marked with symbols above are available. ● , ◎ , and ○ indicate adapter type, and ▲ indicate straight type.
* Adapters indicated as ◎ do not have a keyway. Before using with a shaft having a key, first remove the key.
* ○ indicates model that includes an L key, since adapter specifications prevent a parallel key from fitting. Use this L key when mounting.
* Bore diameters for the L key distinguish between the old JIS and new JIS codes. Specify when ordering.
