About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X50TC
The SC200X50TC is a double-acting pneumatic cylinder delivering substantial force from a compact 50 mm stroke. At 0.5 MPa it generates 15708 N pushing and 15080 N pulling, with a maximum theoretical force of 3204 kgf at 1.0 MPa, making it suitable for heavy clamping and pressing tasks.
This model is configured with a TC centre trunnion mount, supplied with the TCM1 bracket (F-SC200TC), allowing the cylinder to pivot during operation. The 40 mm diameter piston rod and 33 mm adjustable air cushion at each end provide robust guidance and smooth deceleration for the 200 mm bore body.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X50TC Is Used
Heavy Material Transfer
Pivoting pusher or diverter on a conveyor line, using the trunnion mount to swing a heavy product into an adjacent lane with 15.7 kN of force.
Weld Fixture Clamping
Provides stable, high-force clamping in a welding jig where the cylinder body must pivot to clear the part during loading and unloading.
Scissor Lift Actuation
Drives the linkage of a heavy-duty scissor lift table, with the centre trunnion absorbing the angular motion as the platform raises and lowers.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X50TC the Right Cylinder?
For applications needing a pivoting heavy-force actuator, the centre trunnion configuration is ideal. If a fixed linear mount is preferred, consider the same bore with an LB foot mount. Stepping down to a 160 mm bore reduces the 0.5 MPa push force to 10053 N.
When replacing an existing cylinder, match five points exactly: 200 mm bore, 50 mm stroke, PT port thread, TC centre trunnion mounting, and the absence of a magnet. The SC200 is a 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 SC200X50TC FAQ
At 0.5 MPa, the push force is 15708 N and the pull force is 15080 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 28274 N. The theoretical maximum at 1.0 MPa is 3204 kgf.
No. The SC200X50TC is a double-acting cylinder and will not hold position if air pressure is exhausted or the directional valve is centred. For load holding without live pressure, you must add an external rod lock or a pilot-operated check valve.
