ROTARY ACTUATOR |
摘要 |
A rotary actuator includes an output shaft, a housing, a piston, and a friction reducer. The housing includes an arcuate bore that extends around the output shaft. The piston is coupled to the output shaft and moved in the arcuate bore. Pressure fluid acts to move the piston. The friction reducer is configured to reduce friction between a peripheral surface of the piston and an inner circumferential surface of the housing forming the arcuate bore. |
