About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X90
The SC125X90 is a double-acting tie-rod cylinder delivering 6136 N of push force at 0.5 MPa (11045 N at the 0.9 MPa maximum operating pressure). Its 90 mm stroke suits compact clamping, pressing, and short-transfer tasks where high force is needed in a limited linear envelope.
This 125 mm bore model uses a 32 mm diameter piston rod with M27×2 male threads and PT1/2 ports. The body length A is 203 mm, giving a total extended length of approximately 293 mm. An adjustable air cushion (28 mm cushion length) decelerates the piston at end-of-stroke to reduce impact. The SC125X90 is a genuine AirTAC cylinder built for reliable industrial service.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X90 Is Used
Heavy-Duty Clamping
The 6136 N push force at 0.5 MPa and short 90 mm stroke make this cylinder ideal for pneumatic clamping fixtures on welding or machining cells, holding large workpieces securely during processing.
Short-Transfer Pushers
Use the SC125X90 to push heavy pallets or castings across a roller conveyor. The adjustable cushion protects the cylinder and load at the end of each fast transfer cycle.
Press-Fit Assembly
Delivers up to 11045 N at 0.9 MPa for pressing bearings, bushings, or pins into housings. The tie-rod construction handles high cycle counts in automated assembly lines.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X90 the Right Cylinder?
Choose the SC125 bore when your application needs between roughly 6100 N and 11000 N of push force from standard plant air. If your load is lighter—around 3900 N at 0.5 MPa—the SC100 bore saves space and air consumption. For heavier loads, step up to the SC160 bore (10053 N push at 0.5 MPa).
When replacing an existing cylinder, match five points: bore (125 mm), stroke (90 mm), port thread (PT), mounting accessory (basic, no bracket), and magnet option (none). The SC series is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders. For strokes above 300 mm or any side-loaded application, add an external guide or switch to a guided cylinder to protect the rod bearing from bending loads.
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 SC125X90 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 reaches 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
No. The SC series is a tie-rod cylinder and is shorter than an equivalent ISO 15552 cylinder. It is not dimensionally interchangeable. Replace only with another AirTAC SC tie-rod cylinder matching bore, stroke, port thread, mounting, and magnet option.
