About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1550TC
The AirTAC SC125X1550TC is a 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 1550 mm stroke, this non-standard length extends the 125 mm bore beyond the typical 1500 mm maximum, making it suitable for long linear movements in material handling and heavy equipment. The 32 mm diameter piston rod and 28 mm adjustable air cushion ensure robust, decelerated end-of-stroke performance.
This model is configured with a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC125TC), allowing the cylinder to pivot during operation to accommodate swinging or arcing loads. The tie-rod construction keeps the overall length compact compared to ISO 15552 profiles, and the PT1/2 port threads provide a reliable connection for filtered compressed air systems.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1550TC Is Used
Long-Stroke Material Transfer
The 1550 mm stroke pushes or pulls heavy pallets and components across wide conveyor gaps or transfer stations, with the trunnion mount allowing the cylinder body to pivot freely.
Heavy-Duty Clamping & Forming
Generates up to 11045 N of force for pressing, bending, or clamping large metal or composite parts in jigs and fixtures, where a pivoting cylinder body is required.
Gate & Diverter Actuation
Operates large diverters or gates in bulk handling systems. The centre trunnion mount handles the arcing motion, while the adjustable cushion softens the impact at the stroke ends.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1550TC the Right Cylinder?
For applications requiring slightly less force, consider stepping down to the SC100 bore, which provides 3927 N of push at 0.5 MPa. If your load demands a larger rod diameter for enhanced buckling resistance on this 1550 mm stroke, the SC160 bore with its 40 mm rod may be a better fit. Given the extended stroke length, carefully evaluate side loading; an unsupported 32 mm rod at full extension is susceptible to bending. Use an external guide rail or a guided cylinder configuration to protect the rod bearings and ensure linear motion integrity.
To replace an existing cylinder, match five key points: the 125 mm bore, the 1550 mm stroke, the PT1/2 port thread, the TC centre trunnion mounting accessory, and the absence of a built-in magnet. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to another AirTAC SC series unit with identical specifications.
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 SC125X1550TC FAQ
The theoretical push force at 0.5 MPa is 6136 N, and the pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, the 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 than an ISO 15552 profile. The 125 mm bore is an ISO 6430 class cylinder, but it is not dimensionally interchangeable with ISO 15552 cylinders. It is a direct replacement only for another AirTAC SC125 cylinder with matching stroke, port thread, and mounting.
