About the Airtac SC100 Standard Cylinder SC100X550SH
The SC100X550SH is a double-acting pneumatic cylinder with a 100 mm bore and 550 mm stroke, delivering a substantial push force of 3927 N at 0.5 MPa and up to 7068 N at the maximum operating pressure of 0.9 MPa. This model is equipped with a built-in magnet (-S suffix), allowing direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors on the tie-rod barrel for precise, non-contact position feedback.
Engineered for high-temperature environments, the -H suffix designates Viton (FKM) seals, shifting the operating temperature range from the standard -20 to +70 °C up to 0 to +150 °C. The 25 mm diameter piston rod with M20x1.5 threads provides robust linear guidance, while the 29 mm adjustable air cushion at each end decelerates the piston smoothly, protecting the end caps during high-cycle operation. The body length A is 188 mm, giving a total extended length of approximately 738 mm.

Where the Airtac SC100 Standard Cylinder SC100X550SH Is Used
High-Temperature Automation
With Viton seals rated for continuous operation up to 150°C, this cylinder is ideal for actuating dampers, gates, or clamps inside autoclaves, industrial ovens, and foundry equipment.
Heavy Pallet Transfer
The 7068 N push force at 0.9 MPa easily drives heavy pallet stops, transfer lifts, and right-angle pushers on conveyor lines, with the 550 mm stroke covering wide transfer distances.
Sensor-Monitored Pressing
The built-in magnet allows CMSG/DMSG sensors to confirm full extension and retraction, making this cylinder a reliable actuator for heat-assisted pressing, forming, or bonding fixtures.
Is the Airtac SC100 Standard Cylinder SC100X550SH the Right Cylinder?
For applications requiring slightly less force, stepping down to an 80 mm bore (SC80) reduces the push force to 2513 N at 0.5 MPa, which may allow for a smaller, more cost-effective valve and footprint. Conversely, if the 3927 N at 0.5 MPa is marginal for the load, moving up to a 125 mm bore provides a significant jump to 6136 N.
At a 550 mm stroke, the 25 mm rod is well-supported for purely axial loads, but any significant side loading will create a bending moment on the rod bearing. For non-axial loads, an external linear guide or a guided cylinder is strongly recommended to prevent premature seal and bearing wear. For a direct replacement, match the 100 mm bore, 550 mm stroke, PT port thread, built-in magnet (-S), and the basic mounting configuration.
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 SC100X550SH FAQ
At the standard 0.5 MPa operating pressure, the push force is 3927 N and the pull force on the retract stroke is 3681 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 7068 N.
No. This is a standard double-acting cylinder that will drift or drop if air pressure is lost or the directional valve is centered. To safely hold a load or maintain a position without live pressure, you must add an external rod lock, a pilot-operated check valve, or use a mechanical brake.
