About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X810S
The AirTAC SC125X810S is a double-acting single-rod tie-rod cylinder delivering 6136 N of push force at 0.5 MPa and up to 11045 N at the 0.9 MPa maximum operating pressure. With an 810 mm stroke and a 32 mm diameter piston rod, this model is built for heavy linear actuation tasks where consistent thrust and sensor feedback are both required.
The integrated magnet (-S suffix) allows CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for precise end-of-stroke or mid-stroke position detection. The adjustable air cushion (28 mm length) decelerates the piston smoothly, protecting end caps during high-cycle operation. This ISO 6430 class cylinder uses a PT1/2 port and has a body length A of 203 mm.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X810S Is Used
Pallet Transfer & Stops
The 6136 N push force at 0.5 MPa easily lifts and transfers heavy pallets on conveyor junctions. The built-in magnet provides sensor feedback for precise pallet positioning at the 810 mm stroke end.
Heavy Press & Clamping
Delivers up to 11045 N of clamping force at 0.9 MPa for holding large weldments or composite layups. The 28 mm adjustable cushion absorbs impact energy during high-speed clamp cycling.
Material Handling Pushers
Pushes heavy bins or engine blocks off a production line. The long 810 mm stroke clears the conveyor width, while magnetic sensors confirm full retraction before the next cycle starts.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X810S the Right Cylinder?
Select the SC125 when your application needs the force class between the SC100 (3927 N at 0.5 MPa) and the SC160 (10053 N at 0.5 MPa). For this 810 mm stroke, side-load management is essential—an unsupported 32 mm rod at full extension is vulnerable to bending under radial forces. Always use an external guide rail or rod-alignment coupler to protect the rod bearing and seal. For replacement, match five points: 125 mm bore, 810 mm stroke, PT1/2 port thread, the built-in magnet (-S), and your existing mounting accessory. The SC is a tie-rod cylinder 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 SC125X810S FAQ
At the standard 0.5 MPa operating pressure, the cylinder provides 6136 N pushing and 5734 N pulling force. At the maximum operating pressure of 0.9 MPa, the push force increases to 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
Yes. The -S suffix indicates a built-in magnet in the piston. You can clamp CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the tie-rod barrel to detect piston position without additional brackets.
