About the Airtac SC50 Standard Cylinder SC50X320TC
The AirTAC SC50X320TC is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). Its 320 mm stroke is paired with a 20 mm diameter piston rod and an adjustable air cushion (21 mm) that decelerates the piston smoothly at end-of-travel.
This model includes a factory-fitted centre trunnion mount (TC) supplied with the TCM1 bracket, allowing the cylinder to pivot as it actuates. The body length A is 150 mm, giving a total extended length of approximately 470 mm. Ports are PT1/4 with an M16x1.5 rod thread.

Where the Airtac SC50 Standard Cylinder SC50X320TC Is Used
Conveyor Diverter Gates
The centre trunnion mount lets the cylinder swing with the gate arc, while 982 N of push force reliably diverts medium-weight packages on sorting conveyors.
Clamping & Welding Fixtures
Pivoting action suits clamp arms on fabrication jigs. The adjustable cushion protects the mechanism from impact shock during fast clamp/unclamp cycles.
Agricultural Machinery Linkages
Operates chute deflectors or hopper doors on harvesters and spreaders. TPU seals handle dusty, damp environments within the standard -20 to +70 °C range.
Is the Airtac SC50 Standard Cylinder SC50X320TC the Right Cylinder?
Choose the SC50 when your application needs roughly 982 N of push force at standard plant air. If you require more force, step up to the SC63 bore (1559 N at 0.5 MPa); for a lighter, more compact solution, the SC40 delivers 628 N. This 320 mm stroke exceeds 300 mm, so evaluate side-loading carefully — a long, unsupported 20 mm rod can bend under lateral force; use an external linear guide or switch to a guided cylinder if the load is not perfectly axial.
For direct replacement, match five points: 50 mm bore, 320 mm stroke, PT1/4 port thread, centre trunnion (TC) mounting with TCM1 bracket, and the standard TPU seal. This cylinder does not include a magnet; if you need position sensing, order the SC50X320STC variant.
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 SC50X320TC FAQ
At 0.5 MPa, push force is 982 N and 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.
No. The SC50X320TC is a double-acting cylinder and will drift or drop if pressure is lost or the directional valve is centred. To hold a load safely without live pressure, you must add a pilot-operated check valve, rod lock, or external mechanical brake.
