Use of positioning pins
The SHA series SG type actuator has positioning pin holes in the output rotary unit and flange fixed to
the actuator. The SHA series CG type has positioning pin holes only in the output rotary unit.
Use these pins as necessary. For details, refer to [1-6 External dimensions] (P1-11) or the illustrated
specifications.
*1. Do not drive positioning pins into the output rotary unit, but keep proper fitting clearances to the
actuator parts. Failure to do so may result in lower positional accuracy.
*2. The hollow shaft planetary speed reducer model is not equipped with a positioning pin.
