About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X1200STC
The SC200X1200STC is a large-bore double-acting pneumatic cylinder delivering substantial push force of 15708 N at 0.5 MPa and up to 28274 N at the maximum operating pressure of 0.9 MPa. With a 40 mm diameter piston rod and a 33 mm adjustable air cushion, it is engineered to decelerate heavy loads smoothly at the end of a 1200 mm stroke.
This model comes factory-equipped with a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke or mid-stroke position feedback. The TC suffix denotes a centre trunnion mount, supplied with the TCM1 bracket (part code F-SC200TC), allowing the cylinder body to pivot and absorb angular misalignment in swinging applications.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X1200STC Is Used
Sawmill Log Handling
Provides the high force needed to clamp and position large-diameter logs on a carriage, with the trunnion mount allowing the cylinder to pivot as the log is advanced.
Heavy Agricultural Implement Control
Controls the lift and tilt functions on large tillage or seeding equipment, where the 28274 N max force handles heavy ground-engaging tools and the magnet sensors confirm position.
Balers and Compactors
Drives the main compaction ram in a recycling baler, using its 1200 mm stroke to push material deep into the chamber and its adjustable cushion to quiet the impact at cycle end.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X1200STC the Right Cylinder?
Select this 200 mm bore when your application requires push forces in the 15708 N class at standard plant pressure. For a step down in force, the 160 mm bore delivers 10053 N at 0.5 MPa, while the 250 mm bore provides a significant step up to 24544 N. For this 1200 mm stroke, ensure the rod is protected from side loads; an external guide rail or a guided cylinder is strongly recommended to prevent rod bending and premature bearing wear.
When replacing an existing cylinder, match five key points for a drop-in fit: 200 mm bore, 1200 mm stroke, PT port thread, centre trunnion (TC) mounting with the TCM1 bracket, and the built-in magnet for sensor compatibility. This tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard.
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 SC200X1200STC 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 force at 1.0 MPa is 3204 kgf.
No. The SC200 is a double-acting cylinder and will drift or drop if pressure is exhausted or the directional valve is centered. For load holding without live pressure, you must add a pilot-operated check valve, a rod lock, or an external mechanical brake.
