6. Selection
6-1 Selection
Select the appropriate cylinder based on mass of transferred object and transfer speed (Fig.1).
Example 1: For roller type with transfer speed of 15m/min. and the mass of transferred object of 30kg.
Find the intersection if the speed if 15m/min. on the horizontal axis and the mass of 30kg on
the vertical axis in graph, and select RSQ

RZ that falls in the cylinder operating range.
Example 2: Transfer speed of 15m/min., Mass of transferred obje
ct of 60kg, Friction coefficient μ= 0.1,
Lever type (Lever type with lock mechanism).
Find the intersection if the speed if 15m/min. on the horizontal axis and the mass of 60kg on
the vertical axis in graph, and select RSQ
□
40-
□□
DZ that falls in the cylinder operating range.
6-2 Precautions on Selection
Use for stopping the pallet on the conveyor. For stopping the load directly mounted to the cylinder, the
cylinder pushing force acts as lateral load. Please consult SMC in this case.
6-3.Lateral load and operating pressure
The larger the lateral load, the higher the operating pressure required for the stopper cylinder. Set the
operating pressure using the Fig.2. as a guide.
