About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X300SH
The AirTAC SC125X300SH is a double-acting tie-rod cylinder engineered for high-temperature automation, delivering a substantial push force of 6136 N at 0.5 MPa and up to 11045 N at 0.9 MPa. Its 32 mm diameter piston rod and 28 mm adjustable air cushion manage heavy loads smoothly through a 300 mm stroke, with a compact body length A of 203 mm.
Equipped with Viton (FKM) seals, this model operates reliably in ambient temperatures from 0 to +150 °C, making it suitable for ovens, autoclaves, or foundry equipment where standard seals would degrade. The PT1/2 port and M27x2 rod thread provide robust fluid and mechanical connections for demanding industrial tasks.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X300SH Is Used
High-Temperature Material Handling
The Viton seals allow this cylinder to operate inside curing ovens and kiln loaders at up to 150°C, pushing heavy trays or activating damper doors with 11045 N of force.
Heavy-Duty Clamping & Pressing
Apply consistent, high-force clamping in hot molding presses or autoclave lid closures. The 28 mm cushion decelerates the 32 mm rod smoothly, protecting tooling from impact damage.
Foundry & Metalworking Actuation
Operate sand rammers or casting knock-out stations near molten metal. The FKM seals resist heat and aggressive airborne contaminants, ensuring long service life in harsh foundry environments.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X300SH the Right Cylinder?
Select the SC125 for force requirements between 6136 N and 11045 N at standard plant pressures. For a lighter load, the SC100 bore offers 3927 N at 0.5 MPa, potentially reducing air consumption. At a 300 mm stroke on a 32 mm rod, ensure the load is guided and free from side forces; an external guide rail or rod-alignment coupler is recommended to prevent bearing wear and rod bending.
For a direct replacement, match five key points: 125 mm bore, 300 mm stroke, PT port thread, basic (no mounting accessory), and no magnet. This model uses Viton seals—verify the temperature requirement matches the original application's 0 to +150 °C range.
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 SC125X300SH FAQ
At 0.7 MPa operating pressure, this cylinder produces a pushing force of 8590 N and a pulling force of 5734 N on the retract stroke. The maximum pushing force at 0.9 MPa is 11045 N.
No. The SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder (body length A is 203 mm). It is not dimensionally interchangeable. Use it to replace another AirTAC SC125 tie-rod cylinder with matching port, stroke, and mounting specifications.
