About the Airtac SC50 Standard Cylinder SC50X30TC
The SC50X30TC is a double-acting pneumatic cylinder with a 50 mm bore and a short 30 mm stroke, delivering a push force of 982 N at 0.5 MPa. Its centre trunnion mount (TC) with the included TCM1 bracket allows the cylinder to pivot, making it ideal for compact clamping and ejecting mechanisms where the actuator must swing through an arc.
This model features a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 ports. The adjustable air cushion at each end decelerates the piston over the final 21 mm of travel, reducing impact noise and vibration in high-cycle applications. The standard TPU seals provide reliable operation from -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X30TC Is Used
Compact Clamping Fixtures
The short 30 mm stroke and pivoting TC mount suit machine-tool clamps where the cylinder must swing clear for part loading and unloading.
Part Ejection Gates
Delivers a rapid 982 N push at 0.5 MPa to divert small parts on a conveyor. The trunnion mount absorbs the arc motion without rod side-loading.
Welding Positioners
Used in compact welding jigs to position tabs or brackets. The adjustable cushion protects the cylinder from impact at the end of its short, fast stroke.
Is the Airtac SC50 Standard Cylinder SC50X30TC the Right Cylinder?
For a 50 mm bore, this cylinder provides 982 N of push force at 0.5 MPa. If your application requires more force, stepping up to a 63 mm bore increases push force to 1559 N at the same pressure. For space-constrained designs, a 40 mm bore offers 628 N. The 30 mm stroke is a standard length for this bore.
To ensure a correct replacement, match five key points: 50 mm bore, 30 mm stroke, PT1/4 port thread, centre trunnion (TC) mounting with the F-SC50TC bracket, and the absence of a built-in magnet. The SC series 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 SC50 Standard Cylinder SC50X30TC FAQ
At the standard 0.5 MPa operating pressure, the push force is 982 N and the pull force is 825 N. At 0.7 MPa, push force increases to 1374 N. The maximum operating force at 0.9 MPa is 1767 N.
Not directly. The SC50X30TC includes a centre trunnion (TC) mount and the TCM1 bracket (part code F-SC50TC), which allows the cylinder body to pivot. A basic cylinder lacks this pivot point. You must match the mounting style to maintain the machine's kinematics.
