About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X800SH
The SC160X800SH is a large-bore double-acting tie-rod cylinder delivering 10053 N of push force at 0.5 MPa and up to 18095 N at the maximum operating pressure of 0.9 MPa. With an 800 mm stroke, this model is well-suited for heavy industrial actuation where high force and moderate travel are required, such as pressing, clamping, or lifting large assemblies.
This specific variant includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke detection without external brackets. The -H suffix upgrades the seals to Viton (FKM), shifting the operating temperature range to 0 to +150 °C, making it ideal for autoclaves, foundries, or engine test stands. The 40 mm diameter piston rod and 29 mm adjustable air cushion at each end ensure robust guidance and smooth deceleration of heavy payloads.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X800SH Is Used
Hot Press & Molding
The Viton seals withstand 150°C, making this cylinder suitable for hydraulic-free hot press actuation in composite molding, rubber curing, or laminating processes.
Heavy Part Ejection
With 18095 N of force at 0.9 MPa, it reliably ejects large castings or molded parts from dies in foundry or metal-forming environments where ambient heat is high.
Pallet Lift & Transfer
The 800 mm stroke and 10053 N push at standard line pressure handle heavy pallet lifting and horizontal transfer stations in automated warehouses.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X800SH the Right Cylinder?
For applications requiring slightly less force, consider stepping down to the SC125 bore, which provides 6136 N at 0.5 MPa. If your load demands even higher thrust, the SC200 bore offers 15708 N at the same pressure. At an 800 mm stroke, the 40 mm rod provides substantial column strength, but any significant side load should be managed with an external linear guide or rod support to prevent bearing wear and rod deflection. To ensure a correct replacement, match five key attributes: 160 mm bore, 800 mm stroke, PT port thread, the built-in magnet (-S) for sensor compatibility, and the Viton seal material for high-temperature operation.
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 SC160X800SH FAQ
The -H suffix denotes Viton (FKM) seals, giving this cylinder an operating temperature range of 0 to +150 °C, significantly higher than the standard -20 to +70 °C TPU seal version.
Yes. The -S in the model code indicates a built-in magnet on the piston. This allows AirTAC CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the tie-rod barrel for contactless position sensing.
