About the Airtac SC125-160 Standard Cylinder SC160X1250S
The AirTAC SC160X1250S is a double-acting single-rod pneumatic cylinder delivering substantial force for heavy-duty linear actuation. With a 160 mm bore and 1250 mm stroke, this model generates 10053 N of push force at 0.5 MPa and reaches 18095 N at the maximum operating pressure of 0.9 MPa, driven by a 40 mm diameter piston rod.
This -S variant includes a built-in magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the tie-rod barrel for precise, non-contact position sensing. The cylinder features an adjustable air cushion (29 mm length) at both ends to decelerate the piston smoothly, and uses PT1/4 ports with an M36x2 rod thread. Its body length A is 239 mm, giving a total extended length of approximately 1489 mm.

Where the Airtac SC125-160 Standard Cylinder SC160X1250S Is Used
Sawmill & Log Handling
Positions and clamps large timber sections during cutting and debarking operations. The 18095 N push force and long 1250 mm stroke handle heavy wood billets, with the built-in magnet enabling sensor feedback for automated saw lines.
Heavy Agricultural Machinery
Actuates chute deflectors, hopper doors, and boom adjustments on harvesters and spreaders. The tie-rod construction withstands dusty, high-vibration environments, and the magnetic piston allows end-of-stroke confirmation in automated sequences.
Hydraulic Press Unloading
Ejects large formed parts or pushes heavy tooling sleds out of stamping and forming presses. The adjustable cushion decelerates the 40 mm rod smoothly under high inertial loads, protecting the press tooling from impact damage.
Is the Airtac SC125-160 Standard Cylinder SC160X1250S the Right Cylinder?
For applications requiring slightly less force, the 125 mm bore SC125 series provides 11045 N push at 0.9 MPa. If greater force is needed, step up to the 200 mm bore SC200 series, which delivers 28274 N at 0.9 MPa. This SC160X1250S is a tie-rod cylinder, shorter than an ISO 15552 profile, and is not dimensionally interchangeable with ISO 15552 units.
At 1250 mm stroke, the unsupported rod length is significant. Any side loading, even minor, can cause rod deflection, bearing wear, and seal failure. Always guide the load externally with linear rails or rods, or consider a guided cylinder if the application cannot guarantee purely axial force. For direct replacement, match bore (160 mm), stroke (1250 mm), PT port thread, the built-in magnet (-S), and the basic mounting configuration.
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 SC125-160 Standard Cylinder SC160X1250S FAQ
At 0.7 MPa (approximately 100 psi), the cylinder generates 14074 N of push force. At the maximum operating pressure of 0.9 MPa, it produces 18095 N. The theoretical maximum at 1.0 MPa is 2050 kgf.
Yes. The -S suffix in SC160X1250S designates a built-in magnet in the piston. This allows AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors to be mounted externally on the tie-rod barrel for detecting piston position without additional brackets.
