About the Airtac SC50 Standard Cylinder SC50X225SN
The AirTAC SC50X225SN is a 50 mm bore, 225 mm stroke double-acting tie-rod cylinder 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 for mid-range automation tasks.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors and NBR (nitrile) seals (-N suffix). The PT1/4 port thread and M16x1.5 rod thread match standard pneumatic fittings, making it a straightforward choice for general industrial use.

Where the Airtac SC50 Standard Cylinder SC50X225SN Is Used
Material Transfer
Pushes bins or cartons along a roller conveyor with 982 N at 0.5 MPa. The built-in magnet allows end-of-stroke sensing without external brackets.
Clamping & Fixturing
Applies consistent clamping force in a woodworking jig. NBR seals offer good compatibility with common workshop air supplies.
Press Mechanism
Drives a light assembly press requiring 1374 N at 0.7 MPa. The 225 mm stroke provides ample working clearance for part loading.
Is the Airtac SC50 Standard Cylinder SC50X225SN the Right Cylinder?
For higher force, step up to the 63 mm bore SC63 series which provides 1559 N push at 0.5 MPa. For a shorter, more compact unit, the 40 mm bore offers 628 N. This 225 mm stroke is within the 1200 mm maximum standard stroke for bore 50. When replacing, match bore, stroke, PT port thread, the -S magnet option, and NBR seal material to ensure identical fit and function. For strokes over 300 mm, consider an external guide to protect the rod from side-load bending.
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 SC50X225SN FAQ
At 0.5 MPa, push force is 982 N and pull force is 825 N. At 0.7 MPa, push force increases to 1374 N. The maximum operating pressure is 1.0 MPa, delivering 1767 N of push force.
Yes, the -S suffix indicates a built-in magnet. You can clamp CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the tie-rod barrel to detect piston position.
