About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1200TC
The AirTAC SC125X1200TC is a large-bore double-acting pneumatic cylinder delivering a substantial 6136 N of push force at 0.5 MPa (11045 N at the 0.9 MPa maximum operating pressure). With a 1200 mm stroke and a 32 mm diameter piston rod, this ISO 6430 class tie-rod actuator is built for heavy linear tasks requiring significant reach.
This model features a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC125TC), allowing the cylinder to pivot as it strokes—ideal for swinging or articulating loads. The adjustable air cushion (28 mm length) decelerates the piston smoothly at end-of-stroke, protecting the end caps from impact at the standard speed range of 30-500 mm/s.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1200TC Is Used
Material Handling Pushers
The 1200 mm stroke and 6136 N force at 0.5 MPa make this cylinder suitable for pushing heavy pallets or large components off a conveyor line, where the centre trunnion mount allows the cylinder to pivot freely.
Heavy-Duty Clamping
Delivers up to 11045 N of clamping force at 0.9 MPa for large-scale welding fixtures or assembly jigs, holding massive workpieces securely during fabrication processes.
Diverter Gates
Ideal for actuating large diverter gates in chutes or hoppers. The TC mount accommodates the arc of motion, while the 32 mm rod withstands the inertial loads of heavy bulk materials.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1200TC the Right Cylinder?
Select the SC125 when your application demands forces in the 6136-11045 N range. If your load is lighter, stepping down to an SC100 bore reduces push force to 3927 N at 0.5 MPa, saving space and air consumption. For higher forces, the SC160 bore provides 10053 N at the same pressure.
This 1200 mm stroke is long; ensure the rod is not subjected to side loads, which can cause bending or uneven bearing wear. For unsupported loads, use an external linear guide or a guided cylinder. For a direct replacement, match the 125 mm bore, 1200 mm stroke, PT port thread, centre trunnion (TC) mount, and ensure the replacement cylinder does not have a magnet unless your sensors require it.
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 SC125X1200TC 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, push force increases to 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is shorter in overall length than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC tie-rod cylinder or an equivalent tie-rod design with matching bore, stroke, port thread (PT), and centre trunnion mount.
