About the Airtac SC100 Standard Cylinder SC100X820
The AirTAC SC100X820 is a double-acting tie-rod cylinder delivering a push force of 3927 N at 0.5 MPa and up to 7068 N at the maximum operating pressure of 0.9 MPa. With a 100 mm bore and an 820 mm stroke, this model uses a 25 mm diameter piston rod with an M20×1.5 male thread and PT1/2 port connections.
Designed for filtered air (40 µm), it operates reliably between -20 and +70 °C with standard TPU/NBR seals. The 29 mm adjustable air cushion at each end decelerates the piston smoothly, while the body length A of 188 mm keeps the overall envelope compact for a tie-rod cylinder of this force class.

Where the Airtac SC100 Standard Cylinder SC100X820 Is Used
Pallet Transfer
The 820 mm stroke moves pallets or heavy totes across a transfer station, with the 3927 N push force at 0.5 MPa easily handling loaded carriers on roller beds.
Press-Fit Assembly
Delivers up to 7068 N at 0.9 MPa for pressing bushings or bearings into housings. The adjustable cushion softens the end-of-stroke impact, protecting tooling and part alignment.
Baler Door Actuation
Operates a heavy vertical gate or baler door. The 25 mm rod and tie-rod construction withstand the repetitive, high-force cycling common in waste handling and recycling equipment.
Is the Airtac SC100 Standard Cylinder SC100X820 the Right Cylinder?
The SC100X820 sits in the 3927 N push class at 0.5 MPa. If your load requires more force, step up to the SC125 bore (6136 N at 0.5 MPa); for a lighter, more compact solution, the SC80 bore provides 2513 N at the same pressure. At an 820 mm stroke, the extended rod length demands attention to side loading—any off-axis force can bend the 25 mm rod or wear the bearing. Use an external linear guide or a guided cylinder configuration to protect the rod and seals.
When replacing an existing cylinder, match five points exactly: 100 mm bore, 820 mm stroke, PT1/2 port thread, basic (no accessory) mounting, and the absence of a magnet. This 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 SC100 Standard Cylinder SC100X820 FAQ
At 0.5 MPa the push force is 3927 N and the pull force is 3681 N. At 0.7 MPa push rises to 5497 N, and at the maximum operating pressure of 0.9 MPa it reaches 7068 N. The theoretical maximum force at 1.0 MPa is 801 kgf.
No. The SC100X820 is a double-acting cylinder and will drift or drop if pressure is exhausted or the directional valve is centered. For load holding without live pressure, you must add a pilot-operated check valve, an external rod lock, or a mechanical brake.
