About the Airtac SC100 Standard Cylinder SC100X990SH
The SC100X990SH is a double-acting pneumatic cylinder delivering 3927 N push force at 0.5 MPa and up to 7068 N at 0.9 MPa operating pressure. With a 100 mm bore and a 990 mm stroke, this tie-rod actuator is built for long linear movements requiring substantial force, such as material transfer or heavy-duty clamping. The 25 mm diameter piston rod and 29 mm adjustable air cushion provide smooth deceleration at each end of travel.
This model carries the -S suffix for a built-in magnet, allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors for precise position feedback. The -H suffix specifies Viton (FKM) seals, shifting the operating temperature range to 0–150 °C—ideal for hot environments, autoclaves, or applications with aggressive media where standard TPU seals would degrade.

Where the Airtac SC100 Standard Cylinder SC100X990SH Is Used
Hot Press & Molding
The Viton seals withstand 0–150°C, making this cylinder suitable for heated platen presses, composite molding, and thermoforming equipment where standard seals would fail.
Long-Stroke Material Transfer
With 990 mm of travel and 3927 N of push force, it moves heavy pallets, panels, or castings between conveyor lines or into machining centers with reliable sensor feedback.
Autoclave & Sterilization
The FKM seals and magnetic piston allow position monitoring inside autoclaves and sterilizers, handling high-temperature steam cycles without seal degradation.
Is the Airtac SC100 Standard Cylinder SC100X990SH the Right Cylinder?
For applications needing slightly less force, stepping down to an 80 mm bore (2513 N at 0.5 MPa) can reduce air consumption and footprint. For higher force demands, the 125 mm bore provides 6136 N at the same pressure. This 990 mm stroke is within the 1500 mm max standard stroke for the 100 mm bore, so it is a standard configuration. At this stroke length, ensure the rod is externally guided or the load is purely axial; a long unsupported 25 mm rod can bend under side load, causing premature bearing and seal wear.
When replacing an existing cylinder, match five points precisely: 100 mm bore, 990 mm stroke, PT port thread, the built-in magnet for sensor compatibility, and the Viton seal material for high-temperature operation. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.

- ✓ 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 SC100X990SH FAQ
At 0.7 MPa operating pressure, the theoretical push force is 5497 N. The pull force on the retract stroke is 3681 N at 0.5 MPa, accounting for the 25 mm rod area. Maximum operating force at 0.9 MPa is 7068 N.
No. The SC100X990SH is a double-acting cylinder and will drift or drop if air pressure is lost or the directional valve is centered. The adjustable air cushion only decelerates the piston at stroke end—it does not lock or hold position. For load holding without live pressure, add a pilot-operated check valve or an external rod brake.
