About the Airtac SC50 Standard Cylinder SC50X170STC
The AirTAC SC50X170STC is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa). Its 170 mm stroke is well within the 1200 mm maximum standard stroke for the 50 mm bore, making it a robust off-the-shelf choice for medium-duty linear actuation.
This model features a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (TC) supplied with the TCM1 bracket (F-SC50TC) to allow the cylinder to pivot during operation. The 20 mm diameter piston rod and 21 mm adjustable air cushion provide smooth deceleration, while the PT1/4 port ensures straightforward pneumatic connection.

Where the Airtac SC50 Standard Cylinder SC50X170STC Is Used
Part Diverter Gates
The centre trunnion mount allows the cylinder body to pivot, making it ideal for actuating diverter gates on conveyor systems where the load path changes angle.
Clamping & Staking Fixtures
With 1767 N of force at 0.9 MPa, this cylinder provides ample power for pneumatic clamping, riveting, or staking operations in assembly jigs.
Packaging Machinery Linkages
The built-in magnet enables end-of-stroke sensing to confirm cycle completion, critical for high-speed packaging equipment where the cylinder drives a pivoting linkage arm.
Is the Airtac SC50 Standard Cylinder SC50X170STC the Right Cylinder?
For applications needing more force, stepping up to the 63 mm bore provides 1559 N of push at 0.5 MPa. If a lighter, more compact solution is acceptable, the 40 mm bore offers 628 N. The centre trunnion mount on this -STC variant is ideal for swinging loads, but ensure the rod is not subjected to excessive side loading, especially at full extension.
To guarantee a correct replacement, match five key points: 50 mm bore, 170 mm stroke, PT1/4 port thread, the centre trunnion (TC) mounting accessory, and the built-in magnet (-S) for sensor compatibility. This ensures the new cylinder fits the existing pivot points and sensor setup without modification.
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 SC50X170STC FAQ
At the standard operating pressure of 0.7 MPa, the push force is 1374 N and the pull force is 1155 N (calculated from the 825 N pull force at 0.5 MPa). The maximum theoretical push force at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is dimensionally shorter than an ISO 15552 profile cylinder. It is not interchangeable with ISO 15552 mounts. It must replace another AirTAC SC tie-rod cylinder with the same bore, stroke, port thread, and TC mounting.
