About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X210TC
The SC125X210TC is a heavy-duty double-acting pneumatic cylinder delivering 6136 N of push force at 0.5 MPa and up to 11045 N at 0.9 MPa. Its 125 mm bore and 210 mm stroke suit demanding industrial automation tasks, while the 32 mm piston rod and 28 mm adjustable air cushion provide robust, controlled motion.
This model features a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC125TC), allowing the cylinder to pivot during operation—ideal for swinging or articulating loads. As a genuine AirTAC tie-rod cylinder, it offers reliable performance with a body length of 203 mm and an extended length of 413 mm.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X210TC Is Used
Heavy Material Handling
Provides the high force needed for lifting, pushing, or positioning heavy workpieces on conveyors and assembly lines, especially where the load path requires the cylinder to pivot.
Clamping & Pressing
Delivers up to 11045 N of clamping force for welding jigs, forming presses, and machining fixtures, with the trunnion mount allowing flexible alignment.
Agricultural Machinery
Operates reliably in dusty conditions to actuate chutes, gates, and linkages on heavy equipment, with the pivoting TC mount accommodating the arc of motion.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X210TC the Right Cylinder?
Select the SC125 when your application requires a force class between the SC100 (3927 N at 0.5 MPa) and the SC160 (10053 N at 0.5 MPa). The 210 mm stroke is well within the 1500 mm maximum standard stroke for this bore, ensuring standard lead times. For replacement, match the 125 mm bore, 210 mm stroke, PT port thread, TC centre trunnion mount, and the absence of a magnet.
For strokes over 300 mm, consider an external guide or guided cylinder to protect the 32 mm rod from bending under side loads. This ISO 6430 class cylinder is shorter than an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC tie-rod units.
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 SC125X210TC FAQ
At the standard operating pressure of 0.7 MPa, this cylinder provides 8590 N of push force and 5734 N of pull force. The maximum push force at 0.9 MPa is 11045 N.
No. The SC125 is a double-acting cylinder and will not hold position when pressure is exhausted. The air cushion only decelerates the piston at the end of stroke. For load holding without live pressure, you must add a pilot-operated check valve or an external rod brake.
