About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X250TC
The AirTAC SC200X250TC is a large-bore double-acting tie-rod cylinder delivering 15708 N of push force at 0.5 MPa (28274 N at 0.9 MPa), making it suitable for heavy pressing, clamping, and material-forming applications. This model features a 250 mm stroke with a 40 mm diameter piston rod and an adjustable air cushion (33 mm) to decelerate high-inertia loads smoothly.
Supplied with a centre trunnion (TC) mount and TCM1 bracket (part code F-SC200TC), the cylinder is designed to pivot during operation, absorbing side loads in swinging or articulating machinery. The body length A is 244 mm, giving a total extended length of approximately 494 mm. Operating on filtered air from 0.15 to 1.0 MPa, it uses standard PT ports (PT3/4) and TPU seals for a temperature range of -20 to +70 °C.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X250TC Is Used
Heavy Material Handling
Provides the high push force needed to divert or stop heavy pallets and large packages on industrial conveyor lines.
Press-Fit Assembly
Delivers up to 28274 N of force for pressing bearings, bushings, or pins into large housings with controlled, cushioned deceleration.
Swinging Gate Actuator
The centre trunnion mount allows the cylinder to pivot, making it ideal for opening and closing heavy hopper doors or safety gates.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X250TC the Right Cylinder?
Select the SC200 bore when your application requires a push force between roughly 15708 N and 28274 N. If your load is lighter, stepping down to the SC160 bore (10053 N at 0.5 MPa) can reduce air consumption and physical size. For strokes of 250 mm and above, always assess side-loading: an unsupported 40 mm rod can bend under lateral force. Use an external guide rail or a guided cylinder if the load is not perfectly axial.
When replacing an existing cylinder, match five points: 200 mm bore, 250 mm stroke, PT3/4 port thread, centre trunnion (TC) mounting with the TCM1 bracket, and the absence of a magnet. This SC series is a tie-rod design, shorter than an ISO 15552 cylinder, so dimensional interchangeability is limited to other AirTAC SC or equivalent tie-rod 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 SC200X250TC FAQ
At 0.7 MPa (7 bar) operating pressure, the SC200X250TC generates a theoretical push force of 21991 N. The pull force on the retract stroke is 15080 N at 0.5 MPa due to the area reduction from the 40 mm piston rod.
No. The SC200 is a standard double-acting cylinder and will drift or drop if pressure is lost or the directional valve is centered. For load holding, you must add a pilot-operated check valve or an external mechanical rod brake.
