About the Airtac SC40 Standard Cylinder SC40X100H
The SC40X100H is a double-acting tie-rod cylinder with a 40 mm bore and 100 mm stroke, factory-fitted with Viton (FKM) seals for reliable operation in high-temperature environments from 0 to +150 °C. At 0.5 MPa it delivers 628 N push force and 528 N pull force, rising to 1130 N push at the maximum operating pressure of 0.9 MPa.
Its 16 mm diameter piston rod and M12×1.25 rod thread suit moderate clamping and pressing tasks. The body length A is 142 mm, giving a compact extended length of approximately 242 mm. An adjustable air cushion (21 mm cushion length) decelerates the piston at stroke end to reduce impact noise.

Where the Airtac SC40 Standard Cylinder SC40X100H Is Used
Hot Press & Mould Clamping
Viton seals allow the SC40X100H to operate continuously at 150 °C, making it suitable for heated platen presses, tyre mould actuation, and composite curing fixtures where standard seals would degrade.
Autoclave & Sterilisation Equipment
With FKM seals resistant to steam and aggressive cleaning agents, this 100 mm stroke cylinder handles door actuation and tray transfer inside medical autoclaves and laboratory sterilisation chambers.
High-Temperature Diverter Gates
Deploy the SC40X100H on conveyor diverter flaps in baking, drying, or paint-curing lines. The 628 N push force reliably shifts product flow while the Viton seals withstand radiant heat from the process.
Is the Airtac SC40 Standard Cylinder SC40X100H the Right Cylinder?
Choose the SC40X100H when 628 N at 0.5 MPa meets your load requirement and the ambient temperature exceeds the standard 70 °C ceiling. If you need more force, the SC50 series provides 982 N push at the same pressure. For lower force and a smaller footprint, the SC32 delivers 402 N.
When replacing an existing cylinder, match five points: 40 mm bore, 100 mm stroke, PT1/4 port thread, basic (no bracket) mounting, and the Viton seal designation. The SC is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC40X100H FAQ
At 0.5 MPa the cylinder produces 628 N pushing and 528 N pulling. At 0.7 MPa push force is 879 N, and at the maximum operating pressure of 0.9 MPa it reaches 1130 N push. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The SC series is a tie-rod cylinder with a shorter body length than ISO 15552 profile cylinders (body length A is 142 mm for the 40 mm bore). It is not dimensionally interchangeable with ISO 15552. Replace only with another AirTAC SC tie-rod cylinder matching bore, stroke, PT port thread, basic mounting, and Viton seal.
