About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X130TC
The AirTAC SC125X130TC is a double-acting tie-rod cylinder delivering a robust push force of 6136 N at 0.5 MPa (11045 N at 0.9 MPa). With a 125 mm bore and 130 mm stroke, this model features a 32 mm piston rod and an adjustable air cushion of 28 mm to decelerate the piston smoothly at end-of-travel.
This variant is factory-configured with a centre trunnion (TC) mount, supplied with the TCM1 bracket (part code F-SC125TC), allowing the cylinder to pivot for swinging or articulated loads. The body length A is 203 mm, giving a compact footprint for its force class. It operates on 40 µm filtered air at 0.15-1.0 MPa and uses standard TPU seals for a temperature range of -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X130TC Is Used
Conveyor Diverter Gates
The 6136 N push force at 0.5 MPa easily actuates heavy diverter gates on wide conveyor lines, while the centre trunnion mount allows the cylinder to pivot as the gate swings through its arc.
Press Clamping Fixtures
Delivers 11045 N of clamping force at 0.9 MPa for holding large weldments or castings during machining. The adjustable cushion protects the fixture from impact shock on retract.
Heavy-Duty Toggle Linkages
Ideal for driving toggle mechanisms in balers or compactors. The TC centre trunnion absorbs the linkage's angular movement, preventing side-load damage to the 32 mm rod and bearings.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X130TC the Right Cylinder?
Choose the SC125 bore when your application needs between 6136 N (push at 0.5 MPa) and 11045 N (push at 0.9 MPa). If you need less force, step down to the SC100 bore (3927 N push at 0.5 MPa); for more force, move up to the SC160 bore (10053 N push at 0.5 MPa). The 130 mm stroke is well within the 1500 mm maximum standard stroke for this bore.
For a direct replacement, match five points: 125 mm bore, 130 mm stroke, PT port thread, centre trunnion (TC) mounting with TCM1 bracket, and the absence of a magnet. This SC series is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders. Big bores 125-250 are ISO 6430 class.

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 SC125X130TC 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, the push force reaches 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
No. The SC125X130TC is a double-acting cylinder and does not hold position when pressure is exhausted or the valve is centered. The adjustable air cushion only decelerates the piston at stroke end; it is not a locking or holding device. For load holding, add a pilot-operated check valve or an external rod brake.
