About the Airtac SC50 Standard Cylinder SC50X230TC
The SC50X230TC is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa), making it a capable mid-range actuator for industrial automation. Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for the 230 mm stroke, while the PT1/4 port supplies ample flow for speeds up to 800 mm/s.
This model includes a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC50TC), allowing the cylinder to pivot as it strokes—ideal for swinging or articulating loads. The body length A is 150 mm, and the total extended length is approximately 380 mm. It uses standard TPU seals for operation from -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X230TC Is Used
Part Diverter Gate
The 982 N push force and centre trunnion pivot allow the SC50X230TC to swing a diverter gate on a packaging conveyor, routing products without binding.
Clamp & Fixture Actuation
Delivers consistent clamping force for CNC fixtures or welding jigs, with the TC mount absorbing misalignment during the 230 mm stroke.
Hopper or Chute Control
Operates a discharge chute on agricultural processing equipment, where the trunnion mount handles the arcing motion and the TPU seals tolerate dusty conditions.
Is the Airtac SC50 Standard Cylinder SC50X230TC the Right Cylinder?
Choose the SC50 bore when your application needs roughly 1000 N of force at typical plant pressure; stepping down to the SC40 bore delivers 628 N, while stepping up to the SC63 bore provides 1559 N at the same 0.5 MPa. For this 230 mm stroke, the rod bearing is well-supported, but any side load should be handled by an external guide or linear rail—the SC cylinder is a thrust device and rod bending must be avoided.
To replace an existing cylinder, match five points: 50 mm bore, 230 mm stroke, PT1/4 port thread, centre trunnion (TC) mount with TCM1 bracket, and no magnet. This ensures identical fit and function.
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 SC50X230TC FAQ
At 0.5 MPa, push force is 982 N and pull force is 825 N. At 0.7 MPa, push force rises to 1374 N. The maximum operating force at 0.9 MPa is 1767 N push.
No. The SC50X230TC is a double-acting cylinder and will drift or drop if air pressure is lost or the valve is centered. For load holding without live pressure, you must add a pilot-operated check valve or an external mechanical rod lock.
