About the Airtac SC50 Standard Cylinder SC50X480STC
The SC50X480STC delivers 982 N of push force at 0.5 MPa (1767 N at the 0.9 MPa maximum operating pressure), making it a solid mid-range actuator for moderate transfer and clamping tasks. Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide smooth deceleration across the 480 mm stroke, while the built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for reliable end-of-stroke detection.
This model comes factory-configured with a centre trunnion (TC) mount, including the TCM1 bracket, which lets the cylinder pivot during operation—ideal for swinging or articulating loads. The total extended body length is approximately 630 mm (150 mm body length A + 480 mm stroke), and the PT1/4 port supplies ample flow for speeds up to 800 mm/s.

Where the Airtac SC50 Standard Cylinder SC50X480STC Is Used
Part Diverter Gates
The centre trunnion mount allows the cylinder body to pivot, making it perfect for actuating diverter gates on conveyor lines where the 480 mm stroke sorts packages by lane.
Welding Fixture Clamping
With 1767 N of force at 0.9 MPa and magnetic piston sensing, this cylinder confirms clamp engagement in automated welding cells, ensuring parts are held securely before the torch fires.
Material Lift & Tilt Mechanisms
The TC mount absorbs the angular motion in lift-and-tilt tables. The 480 mm stroke provides the linear push, while the trunnion allows the cylinder to follow the table's arc without side-loading the rod.
Is the Airtac SC50 Standard Cylinder SC50X480STC the Right Cylinder?
Choose the SC50 when 982 N at 0.5 MPa fits your load; if you need more force, the SC63 delivers 1559 N at the same pressure. For lighter, faster moves, stepping down to the SC40 (628 N) can reduce air consumption. At 480 mm stroke, ensure the rod is not subjected to side loading—an external guide or a guided cylinder is recommended to prevent rod bearing wear and bending, especially under high cycle rates.
For a direct replacement, match five points: 50 mm bore, 480 mm stroke, PT1/4 port thread, centre trunnion (TC) mounting with the F-SC50TC bracket, and the built-in magnet (-S) for sensor compatibility. This is a genuine AirTAC tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to another SC series unit.
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 SC50X480STC FAQ
At the standard 0.5 MPa operating pressure, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 cylinder, so the mounting dimensions and body length will not match. You must replace it with another AirTAC SC tie-rod cylinder of the same bore, stroke, port thread (PT), and mounting type (TC centre trunnion).
