About the Airtac SC50 Standard Cylinder SC50X220STC
The AirTAC SC50X220STC is a double-acting pneumatic cylinder with a 50 mm bore and 220 mm stroke, delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa). Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration, making it suitable for medium-duty linear tasks.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and ships with a TC centre trunnion mount plus TCM1 bracket (F-SC50TC) for pivoting applications. The standard PT ports and TPU seals suit general industrial environments from -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X220STC Is Used
Part Diverter Gates
The 220 mm stroke and centre trunnion mount allow the cylinder to pivot as it extends, smoothly diverting cartons or components between conveyor lanes.
Clamping & Fixturing
With 982 N of clamping force at 0.5 MPa and magnetic piston sensing, this cylinder confirms clamp engagement in automated welding or assembly fixtures.
Hopper & Chute Actuation
The pivoting TC mount and robust tie-rod construction handle dusty conditions, opening and closing discharge gates on seed or grain hoppers.
Is the Airtac SC50 Standard Cylinder SC50X220STC the Right Cylinder?
Choose the SC50 when your application needs between 500 N and 980 N of push force at standard shop air. If your load is lighter, the SC40 delivers 628 N at 0.5 MPa and may reduce air consumption; for heavier work, the SC63 provides 1559 N at the same pressure. For this 220 mm stroke, the rod bearing is well-supported, but any side load should be managed with an external guide.
To replace an existing cylinder, match five points: 50 mm bore, 220 mm stroke, PT port thread, TC centre trunnion mounting with TCM1 bracket, and the built-in magnet for sensor compatibility.
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 SC50X220STC FAQ
At 0.5 MPa the cylinder provides 982 N extending (push) and 825 N retracting (pull). At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes. The -S suffix denotes a built-in magnet in the piston, allowing AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors to be clamped directly onto the barrel for end-of-stroke or mid-stroke position feedback.
