About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X1000STC
The AirTAC SC160X1000STC is a double-acting tie-rod cylinder delivering 10053 N of push force at just 0.5 MPa, scaling up to a powerful 18095 N at the maximum operating pressure of 0.9 MPa. With a 40 mm diameter piston rod and an M36x2 knuckle thread, this 160 mm bore actuator is built for heavy linear work over a full 1000 mm stroke, supported by a 29 mm adjustable air cushion at each end to decelerate high-inertia loads smoothly.
This specific model ships with a built-in magnet (suffix S) so CMSG, DMSG, or EMSG reed and solid-state sensors clamp directly onto the tie-rod barrel for non-contact position sensing. The TC suffix indicates a centre trunnion mount, supplied complete with the TCM1 bracket (part code F-SC160TC), allowing the cylinder body to pivot as the rod extends and retracts—ideal for swinging or articulating load paths. With a body length A of 239 mm, the total retracted length is compact for its stroke class, and the standard PT1/2 port thread ensures straightforward pneumatic plumbing.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X1000STC Is Used
Pallet & Heavy Conveyor Diverters
The 1000 mm stroke and 10 kN push force at 0.5 MPa allow this cylinder to shift fully loaded pallets or heavy totes across right-angle transfer stations. The centre trunnion mount lets the body pivot, following the diverter arm through its arc without binding.
Large Press & Clamping Fixtures
Delivering up to 18095 N at 0.9 MPa, the SC160X1000STC suits large weldment clamping or laminating press frames. The built-in magnet enables end-of-stroke confirmation via CMSG/DMSG sensors, ensuring the clamp is fully engaged before the cycle proceeds.
Timber & Sawmill Log Positioning
In sawmill infeed systems, this cylinder pushes logs onto the carriage chain over a 1-metre travel. The 40 mm rod and adjustable cushion handle the impact of a heavy log stopping at end-of-stroke, while the trunnion mount absorbs misalignment as the log stack height changes.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X1000STC the Right Cylinder?
Choose the SC160 when your application needs force in the 10 kN range at typical plant pressure; the next step down is the SC125 bore, which provides 6136 N push at 0.5 MPa, while stepping up to the SC200 bore delivers 15708 N at the same pressure. For this 1000 mm stroke, side-load management is critical—never allow the rod to take direct lateral force at full extension, as the 40 mm rod can bend under off-axis loads. Always guide the load externally with linear rails or rods, or consider a guided cylinder if the stroke exceeds 300 mm and side forces are unavoidable.
When replacing an existing cylinder, match five points exactly: 160 mm bore, 1000 mm stroke, PT port thread, centre trunnion (TC) mounting with the TCM1 bracket, and the built-in magnet for sensor compatibility. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders; it must replace another AirTAC SC or an equivalent tie-rod design of the same bore, stroke, and port configuration.

- ✓ 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 SC160X1000STC FAQ
The theoretical push force at 0.5 MPa (5 bar) is 10053 N, and the pull force on the retract stroke is 9425 N. At the maximum operating pressure of 0.9 MPa, the push force rises to 18095 N. These values assume clean, filtered air at 40 µm and a stable supply pressure; real-world force may be slightly lower due to friction and pressure drop in the lines.
This specific model (SC160X1000STC) is supplied with the centre trunnion (TC) mount and TCM1 bracket. The trunnion is the intended pivot point for swinging loads. If your design requires rigid end mounting, you would need a basic model (no mounting suffix) and then order the appropriate foot (LB) or flange (FA/FB) accessory separately using the F-SC160 part code series. The built-in magnet and PT ports remain the same.
