About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X980SH
The AirTAC SC125X980SH is a double-acting single-rod pneumatic cylinder with a 125 mm bore and 980 mm stroke, built for heavy-duty industrial tasks. It generates a substantial 11045 N of push force at the maximum operating pressure of 0.9 MPa, making it suitable for pressing, clamping, and lifting applications. The 32 mm diameter piston rod and M27x2 male knuckle thread provide robust connection to the load.
This model features a built-in magnet (suffix -S) for direct mounting of CMSG/DMSG/EMSG sensors, and Viton (FKM) seals (suffix -H) that extend the operating temperature range to 0–150 °C. The adjustable pneumatic cushion at both ends, with a 28 mm cushion length, effectively decelerates the piston to reduce end-of-stroke impact. As an ISO 6430 class tie-rod cylinder, it offers a compact alternative to larger profile designs.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X980SH Is Used
High-Temperature Pressing
With Viton seals rated for 150 °C, this cylinder is ideal for heated platen presses in laminating or composite curing processes where standard seals would degrade.
Heavy Parts Clamping
Delivering over 11000 N of force, it securely clamps large weldments or castings for machining, with sensor confirmation of the clamped state via the built-in magnet.
Foundry Pusher Actuator
The 980 mm stroke and high force push heavy molds or castings along a cooling line, while the Viton seals resist the radiant heat common in foundry environments.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X980SH the Right Cylinder?
Select the SC125X980SH when your application demands high force in a high-temperature environment. If 6136 N of push force at 0.5 MPa is insufficient, consider this 125 mm bore; if it exceeds your requirement, the SC100 bore provides 3927 N. For this 980 mm stroke, ensure the rod is adequately supported against side loads—external guides or a guided cylinder are recommended to prevent rod bearing wear and bending. For a direct replacement, match the 125 mm bore, 980 mm stroke, PT port thread, built-in magnet, and Viton seal material.

- ✓ 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 SC125X980SH FAQ
At 0.5 MPa, it provides 6136 N pushing and 5734 N pulling. 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 AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable with ISO 15552 types. Only replace with another AirTAC SC tie-rod cylinder matching the same bore, stroke, mounting, and port thread.
