About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X500SH
The SC125X500SH is a heavy-duty double-acting pneumatic 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. Its 32 mm diameter piston rod and 28 mm adjustable air cushion are built to manage high-inertia loads, making this 500 mm stroke actuator a workhorse for demanding industrial sequences.
Equipped with a built-in magnet (-S suffix), this model accepts CMSG, DMSG, and EMSG sensors for direct barrel-mounted position feedback. The -H suffix specifies Viton (FKM) seals, shifting the operating temperature range to 0 to +150 °C, which makes it suitable for hot environments where standard seals would degrade.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X500SH Is Used
Pallet Stop & Lift
With 11045 N of force at 0.9 MPa, this cylinder easily lifts and stops heavy pallets on conveyor lines, providing robust zero-pressure accumulation control.
Press & Clamping Fixtures
Delivers consistent, high clamping force for welding fixtures and assembly presses. The Viton seals allow operation near heat sources without seal failure.
Material Handling Pusher
Ideal for pushing heavy components onto machining centres. The built-in magnet enables end-of-stroke sensing to confirm part transfer in automated cells.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X500SH the Right Cylinder?
For applications needing less force, the 100 mm bore SC100 series provides 3927 N at 0.5 MPa, while stepping up to the 160 mm bore SC160 series offers 10053 N. At a 500 mm stroke, ensure the 32 mm rod is not subjected to significant side loading; if the load path is not perfectly axial, use an external guide rail or a guided cylinder to prevent rod bending and premature bearing wear. To replace an existing unit, match the 125 mm bore, 500 mm stroke, PT port thread, basic mounting configuration, and the -S magnet option for sensor compatibility.
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 SC125X500SH FAQ
At 0.7 MPa, the push force is 8590 N, and the pull force is 5734 N. The maximum push force at the 0.9 MPa operating limit is 11045 N.
No. The SC125X500SH is a double-acting cylinder and will not hold its position if air pressure is lost or the valve is centred. The adjustable air cushion only decelerates the piston at the end of stroke. For load holding without live pressure, you must add an external rod lock or a pilot-operated check valve.
