About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X10
The SC125X10 is a compact-stroke member of the AirTAC SC tie-rod cylinder family, delivering a substantial 6136 N of push force at 0.5 MPa (11045 N at the 0.9 MPa maximum operating pressure). Its 32 mm diameter piston rod and 28 mm adjustable air cushion make it suitable for short, high-force clamping or pressing tasks where space along the cylinder axis is limited.
With a body length A of just 203 mm plus the 10 mm stroke, this double-acting cylinder fits into tight machine envelopes while providing the force of a 125 mm bore. The standard PT ports and TPU seals handle filtered air from -20 to +70 °C, and the adjustable cushion at each end decelerates the piston smoothly to reduce end-of-stroke impact.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X10 Is Used
Short-Stroke Clamping
Delivers over 6000 N of force at 0.5 MPa in a 10 mm stroke, ideal for pneumatic clamping fixtures and workholding on machining centres.
High-Force Pressing
Applies up to 11045 N at 0.9 MPa for short-travel pressing, staking, or riveting operations where a compact cylinder footprint is required.
Die Ejection Assist
Provides a powerful, brief push to assist in ejecting parts from dies or moulds, fitting into tight tooling spaces with its short extended length.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X10 the Right Cylinder?
Choose the SC125X10 when you need high force in a very short linear stroke—its 6136 N at 0.5 MPa is a significant step up from the 3927 N of the SC100 bore. If your stroke needs to grow beyond 25 mm, the same SC125 platform extends to a maximum standard stroke of 1500 mm. For side-loaded applications, even at this short stroke, ensure the load is guided externally; the rod bearing is designed for axial thrust, not bending moments.
To replace an existing cylinder, match five points: 125 mm bore, 10 mm stroke, PT port thread, basic (no accessory) mounting, and no magnet. This model is the base SC125X10 without suffix options—confirm your current cylinder's exact code before ordering.
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 SC125X10 FAQ
At 0.7 MPa operating pressure, the SC125X10 produces 8590 N of push force. The pull force at the same pressure is 5734 N, accounting for the 32 mm rod area.
No. The SC125X10 is a double-acting cylinder and will not hold its position or load if air pressure is exhausted or the directional valve is centred. For load holding without live pressure, you must add a pilot-operated check valve or an external mechanical rod brake.
