In an automated transfer system, which component is described as a rodless cylinder?

• A. Rodless cylinder
• B. Rod-type cylinder
• C. Rotary actuator
• D. Pneumatic gripper

Answer: (A)

Rodless cylinders are linear actuators where the moving load is attached to a carriage that moves along the outside of the cylinder or via a belt/magnetic linkage, so there is no piston rod protruding from the end. This design gives a slim profile and allows for longer strokes in tight space, which is especially useful in automated transfer systems where parts need to move smoothly along a path without interference from a sticking-out rod. The term describes exactly this kind of actuator, making it the best fit for the described component. In contrast, a rod-type cylinder uses a piston with a visible rod that extends out to connect to the load, creating a different geometric setup. A rotary actuator provides rotation rather than straight-line motion. A pneumatic gripper uses compressed air to open and close a grip, not to extend or retract along a path.
