About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X700S
The AirTAC SC125X700S 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 125 mm bore and a 700 mm stroke, this model includes a built-in magnet (suffix -S) that allows CMSG, DMSG, or EMSG sensors to be mounted directly on the barrel for contactless position sensing.
This ISO 6430 class cylinder uses a 32 mm diameter piston rod with an M27x2 knuckle thread and PT1/2 ports. The adjustable air cushion (28 mm length) decelerates the piston smoothly at stroke ends, protecting the end caps during high-speed operation. The body length A is 203 mm, making the total extended length approximately 903 mm.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X700S Is Used
Heavy Material Handling
The 6136 N push force at 0.5 MPa makes this cylinder ideal for lifting and transferring heavy pallets or steel components in industrial logistics systems.
Automated Press Fits
Delivering up to 11045 N at 0.9 MPa, the SC125X700S provides the high insertion force needed for bearing press-fit stations or bushing assembly machines.
Agricultural Machinery Actuation
With its robust tie-rod construction and built-in magnet for position feedback, this cylinder reliably controls chutes, gates, and booms on farming equipment.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X700S the Right Cylinder?
For applications requiring more force, stepping up to the 160 mm bore SC160 series provides 10053 N of push force at 0.5 MPa. If a shorter, more compact actuator is sufficient, the 100 mm bore SC100 series offers 3927 N at the same pressure. At a 700 mm stroke, ensure the rod is protected from side loading; an external linear guide or a guided cylinder configuration is recommended to prevent rod bearing wear and bending.
To replace an existing unit, match five key points: 125 mm bore, 700 mm stroke, PT1/2 port thread, the built-in magnet for sensor compatibility, and the basic mounting style. This cylinder is a direct replacement for another AirTAC SC125 tie-rod cylinder with the same specifications.
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 SC125X700S FAQ
At the standard operating pressure of 0.5 MPa, the push force is 6136 N and the pull force is 5734 N. At 0.7 MPa, push force increases to 8590 N, and at the maximum operating pressure of 0.9 MPa, it reaches 11045 N.
Yes, the -S suffix in the model code SC125X700S indicates a built-in magnet is installed on the piston. This allows you to clamp compatible CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder barrel to detect piston position without additional brackets.
