About the Airtac SC100 Standard Cylinder SC100X30H
The SC100X30H is a short-stroke double-acting cylinder from the AirTAC SC tie-rod series, factory-equipped with Viton (FKM) seals for reliable operation in high-temperature environments up to 150°C. With a 100 mm bore, it generates 3927 N of push force at 0.5 MPa and up to 7068 N at the maximum operating pressure of 0.9 MPa, making it a compact powerhouse for hot-duty clamping and ejecting.
This model features a 30 mm stroke, a 25 mm diameter piston rod with M20x1.5 threads, and a PT1/2 port. The adjustable air cushion (29 mm length) decelerates the piston smoothly at end-of-travel, protecting the end cap. The body length A is 188 mm, giving a total extended length of approximately 218 mm.

Where the Airtac SC100 Standard Cylinder SC100X30H Is Used
Hot Press Clamping
Viton seals enable direct mounting on heated platen presses, laminators, and thermoforming tools where ambient temperatures regularly exceed 70°C, providing 3927 N of clamping force at standard line pressure.
Foundry & Kiln Actuation
Operates reliably in foundry shakeout gates, kiln door lifts, and glass moulding equipment. The 0-150°C seal rating handles radiant heat that would degrade standard TPU seals.
Hot Melt Ejection
Delivers a sharp 30 mm eject stroke in hot-runner injection moulds and die-cast trim tools. The short stroke and high force cycle quickly without excessive air consumption.
Is the Airtac SC100 Standard Cylinder SC100X30H the Right Cylinder?
For applications needing more force at the same 30 mm stroke, stepping up to the SC125 bore increases push force to 6136 N at 0.5 MPa. If a lower force profile is acceptable, the SC80 bore provides 2513 N at the same pressure. The short 30 mm stroke inherently limits side-load moments, but for any off-axis loading, an external linear guide is still recommended to protect the rod bearing.
When replacing an existing cylinder, match five key points: 100 mm bore, 30 mm stroke, PT1/2 port thread, basic (no) mounting accessory, and the H suffix for Viton seals. This SC model 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 SC100 Standard Cylinder SC100X30H FAQ
At 0.7 MPa operating pressure, the theoretical push force is 5497 N and the pull force is 3681 N. These values are based on the 100 mm bore and 25 mm rod diameter. Always apply a safety factor for real-world dynamic loads.
No. The SC100X30H is factory-built with Viton (FKM) seals and is validated for 0 to +150°C. Retrofitting seals on a standard TPU cylinder voids the warranty and may not achieve the full temperature rating due to grease and end-cap compatibility. Always order the H suffix model for high-temperature service.
