About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X300
The SC160X300 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a substantial push force of 10053 N at 0.5 MPa and up to 18095 N at the maximum operating pressure of 0.9 MPa. Its 300 mm stroke is well within the 1500 mm maximum standard stroke for this bore, making it a readily available configuration for medium-travel, high-force linear actuation.
This model features a robust 40 mm diameter piston rod with an M36x2 male thread for secure tooling attachment, and a 29 mm adjustable air cushion at each end to decelerate heavy loads smoothly. The body length A is 239 mm, giving a total extended length of approximately 539 mm. Standard PT3/8 ports supply the filtered air, and the TPU seals provide reliable operation in ambient temperatures from -20 to +70 C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X300 Is Used
Heavy Press & Clamping
Generates up to 18095 N of force at 0.9 MPa, ideal for powering heavy-duty pneumatic presses, assembly fixtures, and material clamping systems that require a short, powerful stroke.
Pallet & Product Transfer
The 300 mm stroke and high force output reliably push heavy pallets or large products onto conveyor lines, transfer stations, or packaging machinery without stalling under load.
Industrial Gate & Damper Actuation
Provides the muscle to open and close heavy hopper gates, diverter chutes, or large ventilation dampers in processing plants, leveraging the cylinder's durable tie-rod construction.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X300 the Right Cylinder?
Select the SC160 bore when your application requires a push force between roughly 10053 N and 18095 N. If your load is lighter, stepping down to an SC125 bore reduces air consumption while still providing 6136 N of push force at 0.5 MPa. For strokes of 300 mm and above, always evaluate side-loading conditions; an unsupported 40 mm rod extending this far can be damaged by bending moments. Use an external guide rail or a guided cylinder assembly if side forces are present.
For a direct replacement, match five critical specifications: a 160 mm bore, a 300 mm stroke, a PT3/8 port thread, the specific mounting accessory (this is a basic model with no brackets), and the absence of a built-in magnet. This ensures dimensional and performance interchangeability with an existing AirTAC SC160X300 unit.
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 SC160X300 FAQ
At the standard 0.5 MPa operating pressure, the push force is 10053 N and the pull force is 9425 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 18095 N. The theoretical maximum force at 1.0 MPa is 2050 kgf.
No, this specific model code (SC160X300) does not include the -S suffix for a built-in magnet. To use CMSG/DMSG/EMSG reed or solid-state sensors for piston position detection, you must order the SC160X300-S variant, which has a magnet installed in the piston.
