About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1100S
The AirTAC SC125X1100S is a double-acting single-rod pneumatic cylinder delivering 6136 N push force at 0.5 MPa and up to 11045 N at 0.9 MPa. With a 125 mm bore and 1100 mm stroke, this ISO 6430 class tie-rod actuator uses a 32 mm diameter piston rod and M27x2 rod thread for robust linear motion.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for contactless position feedback. The adjustable air cushion (28 mm length) decelerates the piston at stroke ends, protecting the end caps during high-speed operation within the 30-500 mm/s speed range.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1100S Is Used
Pallet Lift & Transfer
The 1100 mm stroke and 6136 N push force at 0.5 MPa handle pallet lifting and horizontal transfer stations in logistics hubs, with sensor feedback confirming end-of-travel.
Heavy Part Rejection
In mining or aggregate conveying, the SC125X1100S pushes oversized rocks or defective heavy parts off the belt. The built-in magnet enables mid-stroke sensing for precise timing.
Press Feed & Extraction
Feeding large sheet metal blanks into stamping presses demands a long, forceful stroke. The adjustable cushion absorbs impact at retract, while sensors verify the gripper position before the press cycles.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1100S the Right Cylinder?
Select the SC125 bore when your application requires between 6136 N (push at 0.5 MPa) and 11045 N (push at 0.9 MPa). For lower force needs, step down to the SC100 bore (3927 N at 0.5 MPa); for higher thrust, move up to the SC160 (10053 N at 0.5 MPa). This 1100 mm stroke is within the 1500 mm maximum standard stroke for bore 125.
At 1100 mm stroke, side-load management is critical—the 32 mm rod can bend under off-axis forces. Always guide the load externally with linear rails or rods, or consider a guided cylinder configuration. For replacement, match five points: 125 mm bore, 1100 mm stroke, PT1/2 port thread, the built-in magnet (-S), and the basic (no bracket) 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 AIRTAC SC125-160 Standard Cylinder SC125X1100S FAQ
At 0.5 MPa air pressure, the push force is 6136 N and the pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, push force reaches 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
Yes. The -S suffix in SC125X1100S indicates a built-in magnetic piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the tie-rod barrel to detect piston position without additional brackets.
