About the Airtac SC50 Standard Cylinder SC50X180TC
The SC50X180TC is a double-acting pneumatic cylinder with a 50 mm bore and 180 mm stroke, factory-equipped with a centre trunnion (TC) mount for pivoting applications. At 0.5 MPa it generates 982 N extending thrust and 825 N retracting force, making it a capable mid-range actuator for medium-duty linear tasks.
This model uses a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The adjustable air cushion at each end is 21 mm long, and the body length (dimension A) is 150 mm. Operating pressure spans 0.15–1.0 MPa with a speed range of 30–800 mm/s. The TC mount includes the TCM1 trunnion bracket (order reference F-SC50TC).

Where the Airtac SC50 Standard Cylinder SC50X180TC Is Used
Conveyor Diverter Gate
The SC50X180TC pivots a diverter gate on a packaging line. The centre trunnion mount allows the cylinder body to swing as the gate opens and closes, preventing side loads on the 20 mm rod.
Clamp & Fixture Actuation
Delivers 982 N to operate a welding fixture clamp. The adjustable cushion decelerates the clamp arm smoothly at end-of-stroke, reducing impact on the tooling.
Hopper Door Control
Opens and closes a discharge door on a seed hopper. The trunnion mount absorbs the arc of the linkage, and the TPU seals handle dusty, ambient-temperature conditions reliably.
Is the Airtac SC50 Standard Cylinder SC50X180TC the Right Cylinder?
Choose the SC50 bore when your load requires roughly 1000 N at standard plant pressure; if you need more force, step up to the SC63 which delivers 1559 N at the same 0.5 MPa. For lighter, faster moves the SC40 provides 628 N. This 180 mm stroke is well within the 1200 mm maximum standard stroke for bore 50.
To ensure a straightforward replacement, match five points: 50 mm bore, 180 mm stroke, PT port thread, centre trunnion (TC) mounting, and confirm whether a magnet is needed (this model has no built-in magnet). The TC trunnion allows the cylinder to pivot as the load moves through an arc, reducing rod bending loads.
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 SC50X180TC FAQ
At 0.5 MPa the extending (push) force is 982 N and the retracting (pull) force is 825 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes, provided the existing unit matches the 50 mm bore, 180 mm stroke, PT1/4 ports, and centre trunnion style. The SC50X180TC ships with the TCM1 bracket (part code F-SC50TC). Note that this cylinder does not include a magnet; if your old unit used magnetic sensors, order the -S variant.
