About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X100LB
The AirTAC SC125X100LB is a double-acting pneumatic cylinder delivering 6136 N of push force at 0.5 MPa (11045 N at the 0.9 MPa maximum operating pressure). With a 100 mm stroke and a 32 mm diameter piston rod, it handles medium-force clamping and pressing tasks where a compact installed length is beneficial.
This model is configured with LB axial foot mounts (part code F-SC125LB) for secure surface mounting. The tie-rod construction keeps the cylinder serviceable, and the adjustable air cushion at each end decelerates the 32 mm rod smoothly. As an ISO 6430 class cylinder, it operates in the 30-500 mm/s speed range on standard PT1/2 ports.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X100LB Is Used
Pallet Stop & Lift
The 6136 N push force at 0.5 MPa and foot mounting make this cylinder ideal for raising or stopping heavy pallets on a conveyor line.
Heavy Clamping Fixture
Use the SC125X100LB to power a weldment clamp or assembly press. The LB feet bolt directly to a machine table for a rigid, fixed alignment.
Forming & Bending
Delivers up to 11045 N at 0.9 MPa for sheet-metal forming or tube-bending dies, with the adjustable cushion protecting tooling at the end of the 100 mm stroke.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X100LB the Right Cylinder?
Choose the SC125 bore when your application needs roughly 6000 N of force at standard plant pressure. If you can accept a smaller actuator, stepping down to the SC100 bore provides 3927 N at 0.5 MPa. For higher force, the SC160 bore offers 10053 N at the same pressure.
This 100 mm stroke is well within the 1500 mm maximum standard stroke for the 125 bore, so no special side-load derating is required for the stroke length alone. To ensure a reliable replacement, match five points: 125 mm bore, 100 mm stroke, PT1/2 port thread, LB foot mounting, and the non-magnet specification (no -S suffix).
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 SC125X100LB FAQ
At 0.5 MPa, the push force is 6136 N and the pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
No. The AirTAC SC series is a tie-rod cylinder, not an ISO 15552 profile cylinder. Its body length is shorter than an ISO 15552 unit of the same bore and stroke, so it is not dimensionally interchangeable. Replace it with another AirTAC SC125 tie-rod cylinder matching the 100 mm stroke, PT1/2 ports, and LB foot mount.
