About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1000SH
The SC125X1000SH is a large-bore double-acting pneumatic cylinder delivering 6136 N of push force at 0.5 MPa and up to 11045 N at 0.9 MPa. Its 1000 mm stroke is within the standard range for the 125 mm bore, making it a workhorse for heavy linear actuation tasks.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and Viton (FKM) seals (-H suffix) that shift the operating temperature range to 0 to +150°C. The 32 mm piston rod and 28 mm adjustable air cushion provide robust end-of-stroke deceleration for high-cycle applications.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1000SH Is Used
Heavy Press & Clamping
Generates over 11000 N of force at 0.9 MPa for holding, pressing, or clamping large workpieces in metal fabrication and woodworking fixtures.
Material Handling Gates
The 1000 mm stroke controls large diverter gates or chutes on heavy-duty conveyors, with Viton seals handling dusty, high-temperature environments.
High-Temperature Actuation
Viton seals allow reliable operation in autoclaves, ovens, or foundry equipment up to 150°C, where standard seals would degrade.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1000SH the Right Cylinder?
For applications needing more force, stepping up to the 160 mm bore provides 10053 N at 0.5 MPa. If a shorter, more compact cylinder is acceptable, the 100 mm bore offers 3927 N. At 1000 mm stroke, side-load management is critical—always use an external guide or linear bearing to protect the 32 mm rod from bending moments.
To ensure a correct replacement, match five key points: 125 mm bore, 1000 mm stroke, PT port thread, the integrated magnet (-S), and the Viton seal material. This is an ISO 6430 class tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to equivalent tie-rod designs.
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 SC125X1000SH FAQ
At 0.5 MPa, 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 increases to 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
No. The SC125X1000SH is a double-acting cylinder and will drift or drop if pressure is exhausted. For load-holding in a power-off state, you must add an external rod lock, brake, or a pilot-operated check valve.
