About the Airtac SC32 Standard Cylinder SC32X300H
The SC32X300H is a double-acting tie-rod cylinder with a 32 mm bore and 300 mm stroke, equipped with Viton (FKM) seals for reliable operation in high-temperature environments from 0 to +150 °C. It delivers a push force of 402 N at 0.5 MPa and up to 724 N at the maximum operating pressure of 0.9 MPa, driven by a 12 mm diameter piston rod.
With a compact body length of 140 mm and a 21 mm adjustable air cushion at each end, this cylinder decelerates the piston smoothly to reduce end-of-stroke impact. The PT1/8 port and M10x1.25 rod thread are standard, and the cylinder is designed for filtered air service within a 0.15-1.0 MPa pressure range.

Where the Airtac SC32 Standard Cylinder SC32X300H Is Used
Hot-Zone Actuation
With Viton seals rated to +150 °C, this cylinder is suited for autoclave door mechanisms, drying oven actuators, and foundry tooling where standard seals would degrade.
Small-Part Ejection
The 32 mm bore and 300 mm stroke provide the reach and moderate force needed to eject small plastic or metal parts from moulds and stamping dies in automated cells.
High-Temp Diverter Gates
Operates diverter paddles on conveyors moving hot materials, such as baked goods or warm castings, maintaining consistent speed and cushioning at 30-800 mm/s.
Is the Airtac SC32 Standard Cylinder SC32X300H the Right Cylinder?
For applications needing more force, stepping up to the 40 mm bore SC40 series provides 628 N of push at 0.5 MPa. At a 300 mm stroke, ensure the load is guided and free of side forces; an unsupported 12 mm rod can deflect under lateral loads, so use an external guide or rod alignment coupler for long-stroke applications.
When replacing an existing cylinder, match five key points: 32 mm bore, 300 mm stroke, PT port thread, basic (no bracket) mounting, and the absence of a built-in magnet. This model uses Viton seals, so confirm the temperature requirement matches the 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 SC32 Standard Cylinder SC32X300H FAQ
At 0.7 MPa operating pressure, the SC32X300H generates a theoretical push force of 563 N. The pull force on the retract stroke is 345 N at 0.5 MPa, due to the reduced piston area on the rod side.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder. For example, the SC32 body is 140 mm long. It is not dimensionally interchangeable with ISO 15552 cylinders. Only replace with another AirTAC SC32 tie-rod cylinder matching the same bore, stroke, port, and mounting.
