About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X160
The AirTAC SC125X160 is a double-acting tie-rod 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 160 mm stroke, this ISO 6430 class cylinder features a robust 32 mm diameter piston rod and an M27x2 knuckle thread for secure tooling attachment.
Its adjustable pneumatic cushion (28 mm length) decelerates the piston smoothly at stroke end, protecting end caps from impact. The body length A is 203 mm, resulting in a compact total extended length of approximately 363 mm. The standard PT1/2 port supplies ample flow for the 30-500 mm/s speed range typical of this bore class.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X160 Is Used
Pallet Handling & Stops
The 6136 N push force at 0.5 MPa provides ample power for lifting and stopping heavy pallets on conveyor lines, ensuring reliable material flow in distribution centers.
Heavy-Duty Clamping
Ideal for welding jigs and machining fixtures, the SC125X160 applies consistent, high clamping force to secure large fabrications during automated processing.
Press & Forming Assist
Use this cylinder for auxiliary pressing, bending, or punching operations in metal forming, where its 11045 N maximum force at 0.9 MPa delivers a decisive power stroke.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X160 the Right Cylinder?
For applications needing more force, stepping up to the SC160 bore provides 10053 N at 0.5 MPa. If a shorter, lighter cylinder is acceptable, the SC100 bore offers 3927 N. When matching this SC125X160 for replacement, verify five points: 125 mm bore, 160 mm stroke, PT1/2 port thread, basic mounting (no bracket), and the absence of a built-in magnet. The 160 mm stroke is well-supported, but for strokes of 300 mm or more, consider an external guide to protect the 32 mm rod from bending under side load.
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 SC125X160 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 reaches 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than a typical ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It should only replace another AirTAC SC tie-rod cylinder with matching bore, stroke, port thread, and mounting. The SC125-250 bores are classified as ISO 6430 class.
