About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X75S
The SC250X75S is a double-acting tie-rod cylinder delivering 24544 N of push force at 0.5 MPa (44178 N at 0.9 MPa). Its 250 mm bore and 75 mm stroke suit short, high-force clamping or pressing tasks where space along the cylinder axis is limited.
This model includes a built-in magnet (-S suffix), allowing CMSG/DMSG/EMSG reed or solid-state sensors to mount directly on the barrel for rod-position feedback. The rod is 50 mm diameter with M42x2 threads, PT1" ports, and a 40 mm adjustable air cushion. Body length A is 294 mm; total extended length is approximately 369 mm.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X75S Is Used
Heavy-Duty Press Frames
Short-stroke 250 mm bore cylinder provides up to 44178 N for punch-press or bearing-insertion stations, with magnetic sensors confirming ram position.
Automated Welding Clamps
Delivers high clamping force in a compact 75 mm stroke, holding large fabrications steady. The -S magnet enables end-of-stroke detection for weld-sequence control.
Test Rig Actuation
Applies controlled, repeatable force in material-testing fixtures. Adjustable cushioning protects load cells at stroke end, while sensors signal cycle completion.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X75S the Right Cylinder?
For applications needing slightly less force, the 200 mm bore SC200 series provides 15708 N push at 0.5 MPa. If your load requires the full 250 mm bore but a longer working distance, standard strokes up to 1500 mm are available. This 75 mm stroke is well within the standard range and does not require special side-load considerations for the 50 mm rod at this extension.
To ensure a correct replacement, match five points: 250 mm bore, 75 mm stroke, PT1" port thread, the built-in magnet (-S), and your required mounting accessory (this unit is basic, with no bracket). The SC250 is an ISO 6430 class tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC250X75S FAQ
At 0.5 MPa the cylinder pushes with 24544 N and pulls with 23562 N. At the maximum operating pressure of 0.9 MPa, push force reaches 44178 N. The theoretical maximum at 1.0 MPa is 5006 kgf.
Yes. The -S suffix indicates a built-in magnet around the piston, so you can clamp CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel to detect rod position without external brackets.
