About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X65
The AirTAC SC160X65 is a double-acting tie-rod cylinder delivering substantial force in a compact 65 mm stroke format. At 0.5 MPa it generates 10053 N pushing and 9425 N pulling, while at the maximum operating pressure of 0.9 MPa the thrust reaches 18095 N—ideal for heavy pressing, clamping, or lifting tasks that require a short, powerful linear motion.
Built with a 40 mm diameter piston rod and a PT3/4 port, this cylinder features a 29 mm adjustable air cushion to decelerate the piston smoothly at end of stroke. The body length A is 239 mm, giving a total extended length of approximately 304 mm. Operating temperature range is -20 to +70 °C with the standard TPU/NBR seals.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X65 Is Used
Heavy-Duty Clamping
Short-stroke 10053 N clamping force securely holds large weldments or castings during machining, with the 40 mm rod resisting deflection under high load.
Pallet Lift & Transfer
Provides a powerful 65 mm lift stroke for pallet corner lifts or transfer stations, easily handling multi-ton loads when properly guided.
Press-Fit Assembly
Delivers up to 18095 N at 0.9 MPa for pressing bearings, bushings, or pins into heavy housings, with the adjustable cushion protecting tooling from impact.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X65 the Right Cylinder?
For applications needing slightly less force, stepping down to a 125 mm bore reduces push force to 6136 N at 0.5 MPa, while a 200 mm bore increases it to 15708 N. When replacing an existing cylinder, match all five key points: 160 mm bore, 65 mm stroke, PT3/4 port thread, basic (no bracket) mounting, and the absence of a magnet. The SC 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 SC160X65 FAQ
At 0.5 MPa the push force is 10053 N and the pull force is 9425 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 18095 N. The theoretical maximum force at 1.0 MPa is 2050 kgf.
No. The SC160X65 is a double-acting pneumatic cylinder and does not hold position when air pressure is exhausted or the directional valve is centered. For load-holding applications, you must add an external rod brake, a pilot-operated check valve, or a mechanical lock.
