About the Airtac SC50 Standard Cylinder SC50X300TC
The AirTAC SC50X300TC is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa. With a 300 mm stroke and a 20 mm diameter piston rod, this model is well-suited for medium-force linear tasks like pressing, clamping, or material transfer in automated cells.
This specific configuration includes a centre trunnion mount (TC), supplied with the TCM1 bracket, allowing the cylinder to pivot during operation. The body length A is 150 mm, and the total extended length is approximately 450 mm. It features an adjustable pneumatic cushion to decelerate the piston smoothly at stroke ends, reducing impact and noise.

Where the Airtac SC50 Standard Cylinder SC50X300TC Is Used
Pivoting Conveyor Gate
The TC centre trunnion mount allows this cylinder to swing a diverter gate on a conveyor line, sorting packages with a 1374 N push at 0.7 MPa.
Welding Fixture Clamp
Operates a pivoting clamp arm in a welding jig, holding parts securely with 1767 N of force at full 0.9 MPa line pressure.
Agricultural Implement Actuator
Controls the angle of a chute or deflector plate on harvesting equipment, with the trunnion mount absorbing the oscillating motion.
Is the Airtac SC50 Standard Cylinder SC50X300TC the Right Cylinder?
Select the SC50X300TC when your application requires a pivoting motion and a force of roughly 982 N at standard plant pressure. If you need more force, stepping up to the 63 mm bore provides 1559 N at 0.5 MPa. For a fixed, non-pivoting installation, consider the basic SC50X300 or a foot mount (LB).
For this 300 mm stroke, ensure the load is guided externally if significant side forces are present. The 20 mm rod can bend under high side loads when fully extended. For a direct replacement, match the 50 mm bore, 300 mm stroke, PT port thread, centre trunnion (TC) mount, and the absence of a magnet.
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 SC50 Standard Cylinder SC50X300TC FAQ
At the standard operating pressure of 0.7 MPa, the push force is 1374 N and the pull force is 1155 N (calculated from the 825 N pull force at 0.5 MPa). The maximum push force at 0.9 MPa is 1767 N.
This model will directly replace any AirTAC SC50X300 with a centre trunnion (TC) mount and PT ports. For a non-AirTAC tie-rod cylinder, you must match the 50 mm bore, 300 mm stroke, PT port thread, and the pivoting trunnion mount style exactly.
