About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X50S
The AirTAC SC125X50S is a robust double-acting tie-rod cylinder delivering 6136 N of push force at 0.5 MPa, ideal for short-stroke clamping and pressing tasks. Its 32 mm rod diameter and 28 mm adjustable air cushion provide stable deceleration even under rapid cycling.
This model includes a built-in magnet, allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for reliable end-of-stroke detection. The standard PT port and TPU seals suit general industrial environments from -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X50S Is Used
Short-Stroke Clamping
High force in a compact 50 mm stroke makes it perfect for pneumatic clamping fixtures in machining and welding cells.
Part Ejection
Reliable ejection of heavy parts from conveyor systems or stamping dies, with sensor confirmation of rod position.
Press-Fit Assembly
Delivers controlled 6136 N push for bearing or bushing insertion, with magnetic piston sensing for quality assurance.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X50S the Right Cylinder?
For higher force, step up to the SC160 bore (10053 N push at 0.5 MPa). If a longer stroke is needed, the SC125 standard range extends to 1500 mm. Ensure replacement matches bore, stroke, PT port thread, and the -S magnet option. The 50 mm stroke is a standard length, readily available.
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 AIRTAC SC125-160 Standard Cylinder SC125X50S FAQ
At 0.7 MPa operating pressure, the SC125 bore generates 8590 N of push force. The pull force on the retract stroke is 5734 N due to the 32 mm rod area.
Yes. The -S suffix indicates a built-in magnet, making it compatible with AirTAC CMSG, DMSG, or EMSG sensors that clamp directly onto the tie-rod barrel for non-contact position sensing.
