About the Airtac SC125-160 Standard Cylinder SC160X125TC
The AirTAC SC160X125TC is a double-acting pneumatic cylinder delivering substantial force in a compact tie-rod body. At 0.5 MPa it generates 10053 N pushing and 9425 N pulling, rising to 18095 N at the maximum operating pressure of 0.9 MPa, making it suitable for heavy pressing and clamping tasks.
This model features a 160 mm bore, 125 mm standard stroke, and a 40 mm diameter piston rod with M36x2 male threads. The TC suffix denotes a factory-fitted centre trunnion pivot mount, supplied with the TCM1 bracket (part code F-SC160TC), allowing the cylinder to swing during operation. Body length A is 239 mm, and the adjustable air cushion is 29 mm.

Where the Airtac SC125-160 Standard Cylinder SC160X125TC Is Used
Heavy Press Tool Actuation
The 18095 N thrust at 0.9 MPa drives punch and forming tools in metal fabrication presses, where the trunnion mount allows the cylinder body to align with the tooling arc.
Forestry & Agricultural Machinery
Operates log splitters, baler tensioners, and heavy chute diverters. The pivoting TC mount absorbs misalignment on rugged equipment, and the 40 mm rod withstands shock loads.
Tyre & Rubber Vulcanisation Presses
Provides the high clamping force needed to keep moulds closed during the vulcanisation cycle. The adjustable cushion decelerates the large mass smoothly, protecting the mould edges.
Is the Airtac SC125-160 Standard Cylinder SC160X125TC the Right Cylinder?
Select the SC160 for force requirements between roughly 6000 N and 18000 N. If your load is lighter, stepping down to an SC125 bore reduces the push force to 6136 N at 0.5 MPa, saving air consumption. For heavier loads, the SC200 bore offers 15708 N at the same pressure. The centre trunnion mount is ideal for pivoting applications; ensure the pivot axis is perpendicular to the cylinder centreline. When replacing, match bore, stroke, PT port thread, TC trunnion mounting, and confirm the magnet option if sensors are used.
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 SC125-160 Standard Cylinder SC160X125TC FAQ
At the standard 0.5 MPa operating pressure, the cylinder produces 10053 N extending and 9425 N retracting. At the maximum operating pressure of 0.9 MPa, the extending force increases to 18095 N. The theoretical maximum force at 1.0 MPa is 2050 kgf.
Verify the 160 mm bore and 125 mm stroke match your current unit. This model uses PT3/4 ports and an M36x2 rod thread. The TC mount includes the TCM1 bracket (F-SC160TC); ensure the trunnion pin diameter and distance from the head match your fixture. The SC is a tie-rod cylinder, not an ISO 15552 profile, so check the 239 mm body length A for fit.
