About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1300S
The SC125X1300S is a double-acting pneumatic cylinder delivering 6136 N push force at 0.5 MPa (11045 N at the 0.9 MPa maximum operating pressure). Its 125 mm bore and 1300 mm stroke suit long linear movements where substantial force is needed, while the built-in magnet lets CMSG/DMSG/EMSG sensors clamp directly to the tie-rod barrel for rod-position feedback.
This model is part of the ISO 6430 class tie-rod family, featuring a 32 mm piston rod with M27×2 male knuckle thread and PT1/2 ports. The adjustable air cushion (28 mm length) decelerates the piston smoothly, and the body length A is 203 mm. Operating temperature is -20 to +70 °C with the standard TPU/NBR seals.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1300S Is Used
Pallet & Container Handling
Long-stroke pusher for transferring heavy pallets or containers onto conveyor lines, using the full 1300 mm reach and 11045 N peak push force.
Heavy-Gauge Material Feed
Indexing thick steel sheets or large wooden panels into a press or saw station, with magnetic sensors confirming the extended and retracted positions.
Agricultural Equipment Actuation
Operating large gates, chutes, or bale handling arms on farming machinery, where the tie-rod design withstands dusty environments and the magnet enables position interlocking.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1300S the Right Cylinder?
Select the SC125 bore when your application needs between roughly 5734 N (pull at 0.5 MPa) and 11045 N (push at 0.9 MPa). If you can accept lower force, stepping down to the SC100 bore saves space (3927 N push at 0.5 MPa); for higher demand, the SC160 bore provides 10053 N push at 0.5 MPa. The 1300 mm stroke is within the 1500 mm maximum standard stroke for bore 125.
For strokes of this length, side loads become a critical design factor—an unsupported 32 mm rod can bend under off-axis force. Always use an external guide or linear rail to absorb transverse loads, or consider a guided cylinder. When replacing, match five points: 125 mm bore, 1300 mm stroke, PT1/2 port thread, the built-in magnet (-S suffix), and your required mounting accessory (this unit is basic, no bracket).
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 SC125X1300S FAQ
At 0.5 MPa air pressure it produces 6136 N pushing and 5734 N pulling. At the maximum operating pressure of 0.9 MPa, push force rises to 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
Yes. The -S suffix means a magnet is built into the piston, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors can be clamped onto the tie-rod barrel to detect rod position without external brackets.
