About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X80S
The SC250X80S is a large-bore double-acting tie-rod cylinder with an 80 mm stroke and a built-in magnet for barrel-mounted sensors. It generates 24544 N of push force and 23562 N of pull force at 0.5 MPa, rising to 44178 N push at the maximum operating pressure of 0.9 MPa. This ISO 6430 class cylinder uses a 50 mm diameter piston rod with an M42x2 knuckle thread and PT1 inch ports.
With a body length A of 294 mm, the total extended length is approximately 374 mm. The adjustable pneumatic cushion at each end is 40 mm long, providing effective end-of-stroke deceleration for heavy payloads. The built-in magnet, indicated by the S suffix, allows CMSG, DMSG, or EMSG sensors to clamp directly onto the barrel for reliable, non-contact position sensing in automated sequences.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X80S Is Used
Heavy Pallet Lifting
Provides the high force needed to lift and lower loaded pallets in material handling stations, with sensor feedback confirming full retraction before the next cycle.
Hydraulic Press Alternatives
Delivers up to 44178 N of clean pneumatic force for pressing, forming, or clamping operations where hydraulic power is undesirable, with magnet sensors for stroke-end confirmation.
Large Gate Actuation
Powers heavy diverter gates or chutes in mining and aggregate handling, using the 40 mm cushion to absorb impact and the magnet for open/closed position verification.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X80S the Right Cylinder?
Select the SC250 bore when your application demands push forces above 20000 N at standard plant pressure. If your load is lighter, stepping down to the SC200 bore reduces push force to 15708 N at 0.5 MPa, which can lower air consumption and cost. For any stroke over 300 mm on this 50 mm rod, evaluate side-load and rod-bearing bending moments—an external guide or a guided cylinder is recommended to protect the rod and seals.
For a correct replacement, match five points: 250 mm bore, 80 mm stroke, PT port thread, the built-in magnet (-S), and the basic mounting configuration. This cylinder is not an ISO 15552 profile unit; it is a tie-rod design that is shorter than an ISO 15552 cylinder, so dimensional interchangeability must be verified against another AirTAC SC250 or an equivalent tie-rod cylinder.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X80S FAQ
At 0.7 MPa operating pressure, the SC250 bore produces 34361 N of push force and 32987 N of pull force. The theoretical maximum force at 1.0 MPa is 5006 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 cylinder. It will only drop-in replace another AirTAC SC250 tie-rod cylinder with matching bore, stroke, PT ports, and magnet option. Always check the body length A (294 mm) against your existing mounting dimensions.
