About the Airtac SC80 Standard Cylinder SC80X557
The AirTAC SC80X557 is a double-acting, single-rod pneumatic cylinder with an 80 mm bore and a non-standard 557 mm stroke. Operating on filtered air at 0.15-1.0 MPa, it generates a push force of 2513 N at 0.5 MPa and up to 4523 N at 0.9 MPa, making it a robust choice for medium-to-heavy linear actuation tasks.
This model features a 25 mm diameter piston rod with an M20x1.5 male thread and PT3/8 port connections. The cylinder body length (A) is 182 mm, giving an approximate extended length of 739 mm. It includes an adjustable air cushion (28 mm length) to decelerate the piston smoothly at stroke ends, reducing impact and noise within its 30-800 mm/s speed range.

Where the Airtac SC80 Standard Cylinder SC80X557 Is Used
Material Transfer
Pushes heavy totes or pallets off a main conveyor line onto a gravity spur, using its 2513 N push force at standard plant pressure to handle dense loads reliably.
Press-Fit Assembly
Provides the controlled 4523 N thrust at 0.9 MPa to press bearings or bushings into housings in a semi-automated assembly station, with the adjustable cushion protecting the part from impact damage.
Bin Diverter Gate
Actuates a diverter chute in a gravity-fed sorting system, directing bulk product flow between two destinations. The long 557 mm stroke allows for a wide, sweeping gate movement.
Is the Airtac SC80 Standard Cylinder SC80X557 the Right Cylinder?
Select the SC80X557 when your application requires a force class between the SC63 (1559 N push at 0.5 MPa) and the SC100 (3927 N push at 0.5 MPa). For this non-standard 557 mm stroke, which exceeds the 1500 mm maximum standard for the 80 bore, confirm lead time as it is a made-to-order item. For strokes over 300 mm, be cautious of side loads; the 25 mm rod may require an external linear guide to prevent bending and premature bearing wear.
For direct replacement, match the 80 mm bore, 557 mm stroke, PT3/8 port thread, basic (no bracket) mounting, and the absence of a magnet. This cylinder 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 SC80 Standard Cylinder SC80X557 FAQ
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is shorter in overall length than a comparable ISO 15552 profile cylinder. It is not dimensionally interchangeable. For replacement, you must match another AirTAC SC80 cylinder with the same stroke, port, and mounting.
