About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X25TC
The SC160X25TC is a double-acting tie-rod cylinder delivering a substantial 10053 N of push force at 0.5 MPa (18095 N at the 0.9 MPa maximum operating pressure). With a 25 mm stroke and a 40 mm diameter piston rod, it is built for short, high-force clamping, pressing, or positioning tasks where a compact extended length is critical.
This model is equipped with a TC centre trunnion mount (supplied with the TCM1 bracket, part code F-SC160TC), allowing the cylinder body to pivot during operation. The adjustable air cushion (29 mm length) decelerates the piston smoothly at both ends, protecting the end caps in high-cycle applications. Ports are PT3/4.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X25TC Is Used
Heavy-Duty Clamping
Short 25 mm stroke and 10053 N force at 0.5 MPa make it ideal for powerful, repeatable workpiece clamping in machining centres and welding fixtures.
Die Cushion Actuation
Delivers controlled, high-force movement for short-travel die cushion pins or stripper plates in metal stamping presses, with adjustable end-of-stroke cushioning.
Pivoting Conveyor Gate
The TC centre trunnion mount allows the cylinder to swing, perfect for actuating a heavy diverter gate or chute on a conveyor line with a short, decisive throw.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X25TC the Right Cylinder?
For short-stroke, high-force applications, the SC160 provides 10053 N at 0.5 MPa. If your force requirement is lower, stepping down to the SC125 bore reduces push force to 6136 N at the same pressure. For even higher forces, the SC200 bore offers 15708 N.
When replacing an existing cylinder, match five points: 160 mm bore, 25 mm stroke, PT3/4 port thread, centre trunnion (TC) mounting, and the absence of a magnet. The SC series is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC160X25TC FAQ
At 0.7 MPa (7 bar) operating pressure, the theoretical push force is 14074 N. The maximum operating force at 0.9 MPa is 18095 N. Always design with a safety margin for dynamic loads.
No. The SC160X25TC is a double-acting cylinder and will not hold its position if air pressure is exhausted or lost. The piston can drift or drop. For load holding without live pressure, you must add an external rod lock, brake, or a pilot-operated check valve.
