About the Airtac TWG Stop Cylinder TWG50X30C
Round rod stopper on the AirTAC TWG50 platform: a double acting, flange mounted cylinder with a Dia 50 mm bore and a 30 mm stroke (tolerance +1.0/0 mm). The adjustable mounting height flange lets you set the rod to the exact pallet line on the machine, and air pressure from 0.15 to 1.0 MPa raises and lowers the stopper; proof pressure is 1.5 MPa (215 psi).
The plain round rod (stopper code C) suits workpieces that present a stable leading edge, and the thicker piston rod of the TWG50 resists impact better than a standard cylinder body. This code carries no magnet, so there is no S option here and no built-in magnetic position sensing; add external switches if feedback is required. It runs on air filtered by a 40 um element, works from -20 to +70 C, uses a bumper cushion and needs no lubrication.

How to choose
Within the TWG50 ordering table this code pairs the longest 30 mm stroke with the simplest stopper, C round rod. Choose it over TWG50X30B when the flat rod is unnecessary, over TWG50X30R when loads do not need to roll onto the stopper, and over TWG50X30K or TWG50X30KF when the lever roller with oil cushion is more than the application needs. Shorter 20 and 25 mm strokes and the S magnet version stay available on the same bore.
Applications
Pallet stop on a conveyor line
Set the flange height once, then use the 30 mm stroke round rod to catch pallets presented edge-on, with air between 0.15 and 1.0 MPa cycling the stopper up and down.
Adjustable stop height at the frame
Where several product heights share one conveyor, the adjustable mounting height flange lets this Dia 50 cylinder be repositioned without changing the PT1/8 air piping.
Workpiece hold before a machining station
The impact-resistant thicker piston rod and bumper cushion make the round rod a simple mechanical gate for parts entering a fixture, with no lubrication needed in service.
FAQ
What are the key figures of the TWG50X30C?
Dia 50 mm bore, 30 mm stroke (+1.0/0 mm tolerance), double acting, round rod stopper (code C), no magnet, PT1/8 port, operating pressure 0.15 to 1.0 MPa with 1.5 MPa (215 psi) proof pressure, temperature -20 to +70 C, bumper cushion, no lubrication required, air filtered by a 40 um element.
Does this version sense stopper position?
No. TWG50X30C omits the S magnet option, so no magnetic position sensing is built in. If you need electronic feedback, either order an S-suffixed TWG50 or plan external limit switches, and confirm exact sensor mounting from the datasheet.
