About the Airtac SC40 Standard Cylinder SC40X1000H
The AirTAC SC40X1000H is a double-acting tie-rod cylinder engineered for long-stroke applications in elevated-temperature environments. With a 40 mm bore and 1000 mm stroke, it provides 628 N of push force at 0.5 MPa and 1130 N at 0.9 MPa, driven by a 16 mm diameter piston rod with M12x1.25 male threads.
Equipped with Viton (FKM) seals, this model operates reliably from 0 to +150 °C, making it suitable for autoclaves, drying ovens, and foundry equipment. The adjustable air cushion (21 mm length) decelerates the piston smoothly at end-of-stroke, while the PT1/4 port supplies filtered air at 0.15–1.0 MPa. Total extended body length is approximately 1142 mm.

Where the Airtac SC40 Standard Cylinder SC40X1000H Is Used
Autoclave & Sterilizer Actuation
Viton seals withstand 150 °C steam cycles, making the SC40X1000H ideal for opening and closing autoclave doors or positioning medical sterilizer trays.
Drying Oven Pusher
Delivers 1130 N at 0.9 MPa to push product carts through hot-air drying tunnels where standard seals would degrade.
Foundry Mould Clamping
Operates reliably near molten metal handling equipment, using the 1000 mm stroke for long-reach mould closure in high-ambient-temperature foundry cells.
Is the Airtac SC40 Standard Cylinder SC40X1000H the Right Cylinder?
Choose the SC40 bore when your application needs around 628 N at 0.5 MPa—stepping up to SC50 delivers 982 N, while SC32 provides 402 N for lighter loads. For this 1000 mm stroke, side-load management is critical: support the rod externally or use a guided cylinder if lateral forces are present, as the 16 mm rod can bend under unsupported side loads. When replacing an existing unit, match bore, stroke, PT thread, and note that this model has Viton seals and no magnet—add -S if sensor mounting is required.
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 SC40 Standard Cylinder SC40X1000H FAQ
At 0.5 MPa the cylinder delivers 628 N extending and 528 N retracting. At 0.7 MPa these values rise to 879 N push and 739 N pull (calculated proportionally from the 0.5 MPa data).
No. The SC series is a tie-rod cylinder with a shorter body length than ISO 15552 profile cylinders—mounting dimensions and overall length differ. Only replace with another AirTAC SC cylinder matching bore, stroke, PT port, and Viton seal specification.
