About the Airtac SC50 Standard Cylinder SC50X1200TC
The AirTAC SC50X1200TC is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa), making it a capable mid-range actuator for long linear movements. With a 50 mm bore, 20 mm piston rod, and a full 1200 mm stroke, this model is built on a robust tie-rod construction that is shorter than an ISO 15552 cylinder, saving space in machine frames.
This specific configuration includes a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC50TC), allowing the cylinder to pivot during operation—ideal for swinging or articulating loads. The standard PT1/4 ports, TPU seals with a -20 to +70 °C range, and 21 mm adjustable air cushion ensure reliable, controlled deceleration at the end of this long stroke.

Where the Airtac SC50 Standard Cylinder SC50X1200TC Is Used
Long-Reach Part Transfer
The 1200 mm stroke and 982 N push force efficiently shift heavy components between distant conveyor stations or pallets in automated assembly lines.
Pivoting Clamp Actuation
The centre trunnion mount allows the cylinder body to pivot, making it perfect for actuating large swing clamps or toggle mechanisms on welding and machining fixtures.
Bin Tipper Actuator
Delivers the long, controlled stroke and mid-range force needed to tilt heavy bins or hoppers for material handling, with the trunnion absorbing the arcing motion.
Is the Airtac SC50 Standard Cylinder SC50X1200TC the Right Cylinder?
Choose the SC50 bore when your application requires between 982 N (push at 0.5 MPa) and 1767 N (push at 0.9 MPa). If your force requirement is lower, stepping down to the SC40 bore (628 N push at 0.5 MPa) can reduce air consumption. For higher forces, the SC63 bore provides 1559 N at the same 0.5 MPa pressure.
At a 1200 mm stroke, the 20 mm rod is susceptible to bending under side loads. Always use an external guide or a guided cylinder assembly to prevent rod bearing damage and ensure linear motion. For direct replacement, match five key points: 50 mm bore, 1200 mm stroke, PT1/4 port thread, centre trunnion (TC) mounting with TCM1 bracket, and the standard non-magnetic piston.

- ✓ 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 SC50 Standard Cylinder SC50X1200TC FAQ
At the standard 0.5 MPa operating pressure, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than a standard ISO 15552 profile cylinder. It is not dimensionally interchangeable with ISO 15552 mounts. It is a direct replacement only for another AirTAC SC50 tie-rod cylinder with matching stroke, port thread, and TC trunnion mount.
