About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X90S
The SC125X90S is a double-acting pneumatic cylinder delivering 6136 N of push force at 0.5 MPa, rising to 11045 N at the maximum operating pressure of 0.9 MPa. Its 125 mm bore and 90 mm stroke suit medium-travel, high-force clamping and pressing tasks. The built-in magnet (denoted by the -S suffix) allows direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for reliable end-of-stroke detection.
This model features a 32 mm piston rod with an M27x2 knuckle thread and PT1/2 ports. The adjustable air cushion (28 mm length) decelerates the piston smoothly, protecting end caps during high-cycle operation. As an ISO 6430 class tie-rod cylinder, the SC125X90S provides robust, serviceable performance for demanding industrial automation.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X90S Is Used
Pallet Stop & Lift Gates
The 6136 N push force at 0.5 MPa easily raises heavy pallet stops or lift gates in material handling lines, with the magnetic piston enabling precise position confirmation via barrel-mounted sensors.
Heavy-Duty Clamping Fixtures
Delivers stable, high-force clamping for welding jigs and machining fixtures. The adjustable cushion absorbs impact at the end of the 90 mm stroke, reducing vibration on the workpiece.
Press & Forming Assist
Ideal as an assist cylinder in small hydraulic or pneumatic presses, providing up to 11045 N of force at 0.9 MPa for forming, riveting, or stamping operations in short-cycle automated cells.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X90S the Right Cylinder?
For applications needing slightly less force, stepping down to an SC100 bore reduces push force to 3927 N at 0.5 MPa, while an SC160 bore increases it to 10053 N. The 90 mm stroke is well within the 1500 mm maximum standard stroke for this bore, ensuring standard availability. When replacing an existing cylinder, match five key points: 125 mm bore, 90 mm stroke, PT port thread, the basic mounting style, and the integrated magnet (-S) for sensor compatibility. This tie-rod design is shorter than an ISO 15552 profile cylinder and is not dimensionally interchangeable with that standard.
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 SC125X90S FAQ
At the standard operating pressure of 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 force at 1.0 MPa is 1251 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder of the same bore and stroke. It is not dimensionally interchangeable with ISO 15552. For a direct replacement, match another AirTAC SC tie-rod cylinder with the same bore, stroke, port type, and magnet option.
