About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X300
The AirTAC SC125X300 is a double-acting tie-rod cylinder delivering a substantial 6136 N of push force at 0.5 MPa (11045 N at the maximum 0.9 MPa operating pressure). With a 32 mm piston rod and a 300 mm stroke, this ISO 6430 class cylinder is built for heavy linear actuation tasks where robust force output and structural rigidity are required.
This model features a 28 mm adjustable air cushion at each end to decelerate high inertial loads smoothly, protecting the end caps. The body length A is 203 mm, giving a total extended length of approximately 503 mm. The standard PT1/2 port and M27x2 rod thread ensure secure, high-flow pneumatic connections.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X300 Is Used
Pallet Stop & Lift Gates
The high force output at 0.5-0.7 MPa makes the SC125X300 ideal for raising heavy pallet stops or lift-and-transfer gates in automated conveyor systems, reliably holding position against the weight of loaded pallets.
Heavy Press & Clamping Fixtures
Deploy this cylinder in welding or assembly jigs requiring over a tonne of clamping force. The 300 mm stroke provides ample clearance for part loading, while the adjustable cushion absorbs impact during rapid clamp actuation.
Agricultural Equipment Actuation
Commonly used on large agricultural implements for chute direction or hopper door control, where the robust tie-rod construction withstands dirty, high-vibration environments and the 125 mm bore provides the necessary force.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X300 the Right Cylinder?
Select the SC125 when your application demands between 5000 and 11000 N of force at standard shop air pressures; for lighter loads around 3900 N, stepping down to the SC100 bore can reduce air consumption and physical size. For strokes of 300 mm and above, always evaluate side-load conditions—a 32 mm rod extending 300 mm is susceptible to bending under off-axis forces. Use an external guide rail or a guided cylinder assembly to protect the rod bearing and seals from premature wear and ensure linear motion accuracy.
For direct replacement, match five critical points: 125 mm bore, 300 mm stroke, PT1/2 port thread, your specific mounting accessory (this is a basic body, order mounts like F-SC125LB or F-SC125TC separately), and the absence of a built-in magnet. This ensures identical form, fit, and function with your existing AirTAC SC tie-rod cylinder.

- ✓ 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 SC125X300 FAQ
At 0.7 MPa operating pressure, the theoretical push force is 8590 N and the pull force is 5734 N. The maximum push force at 0.9 MPa is 11045 N. These values assume a static condition; for dynamic applications, factor in a load ratio of 50-70%.
This specific model code SC125X300 does not include the '-S' magnet option, so the piston does not have a built-in magnetic ring. To use CMSG/DMSG/EMSG sensors for position feedback, you would need to order the SC125X300-S variant, which includes the magnet and allows sensors to be clamped directly onto the tie-rod barrel.
