About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X150TC
The SC125X150TC 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 125 mm bore and a 150 mm standard stroke, it features a 32 mm piston rod with an M27x2 knuckle thread for robust mechanical connections.
This configuration includes the factory-fitted TC centre trunnion mount, supplied with the TCM1 bracket (order code F-SC125TC), allowing the cylinder to pivot during its stroke. The body length A is 203 mm, giving a total extended length of approximately 353 mm, and the adjustable air cushion is 28 mm to decelerate the piston smoothly.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X150TC Is Used
Heavy Material Transfer
The 6136 N push force at 0.5 MPa easily shifts pallets or heavy components across a conveyor junction, with the trunnion mount allowing the cylinder to swing freely.
Clamping & Pressing
Ideal for high-force clamping fixtures in machining centres, using the full 11045 N at 0.9 MPa to secure large workpieces during milling or drilling operations.
Agricultural Machinery Actuation
Operates chute deflectors or hopper gates on harvesters and spreaders, where the pivoting TC mount accommodates the arcing motion of the linkage.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X150TC the Right Cylinder?
For higher force, step up to the 160 mm bore which provides 10053 N at 0.5 MPa. If 6136 N is more than required, the 100 mm bore offers 3927 N. The 150 mm stroke is well within the 1500 mm maximum standard stroke for this ISO 6430 class bore.
To ensure a direct replacement, match five key points: 125 mm bore, 150 mm stroke, PT port thread, TC centre trunnion mounting, and the absence of a magnet. Due to the heavy 32 mm rod, side-load bending is less of a concern at this stroke, but for guided motion, consider an external linear guide.
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 SC125X150TC FAQ
At the standard 0.5 MPa operating pressure, 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 increases to 11045 N.
The TC mount is a factory-fitted, non-removable centre trunnion. It is supplied with the TCM1 bracket and is designed to be positioned along the barrel body. The complete assembly pivots to prevent bending stress on the piston rod.
