About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X600STC
The AirTAC SC125X600STC is a robust double-acting pneumatic cylinder delivering 6136 N of push force at 0.5 MPa and up to 11045 N at the maximum operating pressure of 0.9 MPa. With a 600 mm stroke, this model is built for heavy industrial linear actuation, featuring a 32 mm diameter piston rod and an M27x2 knuckle thread for secure tooling attachment.
This variant includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and is supplied with a centre trunnion (TC) mount including the TCM1 bracket, allowing the cylinder to pivot during operation. The body length A is 203 mm, and the adjustable cushion is 28 mm, providing effective end-of-stroke deceleration for high-cycle applications.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X600STC Is Used
Heavy Part Clamping
Provides over 1.1 tonnes of clamping force at 0.9 MPa for securing large weldments or castings in machining centres.
Conveyor Diverting
The trunnion mount allows the cylinder to pivot, making it suitable for actuating heavy diverters on wide conveyor systems.
Press Tool Actuation
Delivers the high force needed for forming or punching operations, with sensor feedback confirming each cycle.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X600STC the Right Cylinder?
Select the SC125X600STC when your application requires a pivoting mount and sensor feedback. The centre trunnion (F-SC125TC with TCM1 bracket) is ideal for swinging loads, while the built-in magnet enables precise position sensing without external flags. If your force requirement is lower, consider stepping down to the SC100 bore, which provides 3927 N at 0.5 MPa.
For this 600 mm stroke, ensure the load is guided externally if significant side forces are present, as the 32 mm rod can be subject to bending moments. For a direct replacement, match the 125 mm bore, 600 mm stroke, PT port thread, TC mount, and magnet option exactly. This cylinder is an ISO 6430 class tie-rod design, not interchangeable with ISO 15552 profiles.

- ✓ 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.
