About the Airtac SC50 Standard Cylinder SC50X225STC
The SC50X225STC is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa), built around a 20 mm diameter piston rod with M16x1.5 male threads. Its 225 mm stroke sits well within the 1200 mm maximum standard stroke for the 50 mm bore, making this a readily available configuration.
This model ships with a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors, and the TC centre trunnion mount (supplied with the TCM1 bracket, accessory code F-SC50TC). The trunnion allows the cylinder body to pivot, accommodating swinging loads without side-loading the rod. Standard TPU seals give an operating range of -20 to +70 °C, and the adjustable air cushion at each end (21 mm cushion length) decelerates the piston for smooth, quiet stopping.

Where the Airtac SC50 Standard Cylinder SC50X225STC Is Used
Part Diverter Gates
The centre trunnion mount lets the cylinder pivot as it extends, ideal for swinging diverter arms on packaging conveyors. Magnetic piston sensors confirm gate position at each end of the 225 mm stroke.
Clamping & Fixturing
With 982 N of clamping force at standard line pressure, this cylinder suits medium-duty CNC fixture clamping. The built-in magnet enables sensor feedback to interlock the machine cycle.
Hopper & Chute Actuation
Operates chute doors or flow gates on agricultural handling equipment. The trunnion mount absorbs the arc motion, and TPU seals handle dusty, ambient-temperature environments reliably.
Is the Airtac SC50 Standard Cylinder SC50X225STC the Right Cylinder?
For applications needing slightly more force, stepping up to the 63 mm bore provides 1559 N push at 0.5 MPa, while the 40 mm bore offers 628 N if space is tighter. The SC50X225STC is a genuine AirTAC tie-rod cylinder; when replacing an existing unit, match all five key points: 50 mm bore, 225 mm stroke, PT port thread, centre trunnion (TC) mounting, and the built-in magnet for sensor compatibility. The 225 mm stroke is moderate, but if the rod sees any side load, consider an external linear guide to protect the rod bearing and seals from premature wear.
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 SC50X225STC FAQ
At 0.5 MPa supply pressure, the cylinder produces 982 N extending (push) and 825 N retracting (pull). At 0.7 MPa, push force rises to 1374 N. The maximum operating pressure is 1.0 MPa, yielding 1767 N push.
Yes. The -S suffix indicates a built-in magnet on the piston, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clamp directly onto the barrel tie-rods to detect end-of-stroke or intermediate positions.
