About the Airtac SC80 Standard Cylinder SC80X825S
The AirTAC SC80X825S is a double-acting single-rod pneumatic cylinder delivering a push force of 2513 N at 0.5 MPa and up to 4523 N at 0.9 MPa operating pressure. With an 80 mm bore and 825 mm stroke, this model features a 25 mm diameter piston rod and PT3/8 port threads, making it a robust choice for medium-to-heavy linear actuation tasks.
The built-in magnet (denoted by the -S suffix) allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the tie-rod barrel for precise, non-contact position sensing. Its 28 mm adjustable air cushion decelerates the piston smoothly at stroke ends, and the total extended body length is approximately 1007 mm (182 mm body length A + 825 mm stroke).

Where the Airtac SC80 Standard Cylinder SC80X825S Is Used
Material Transfer Gates
The 825 mm stroke and 2500 N push force effectively actuate diverter gates on wide conveyor lines, sorting packages or bulk materials with sensor-confirmed end-of-stroke positions.
Heavy-Duty Clamping
Ideal for welding or assembly jigs requiring a long retraction distance for part loading. The built-in magnet enables sensor feedback to interlock the clamp position with the machine cycle.
Pallet Push-Off Stations
Provides the long reach needed to push full pallets off a stretch-wrapper turntable onto an exit conveyor, with the adjustable cushion absorbing the impact of the moving mass.
Is the Airtac SC80 Standard Cylinder SC80X825S the Right Cylinder?
Choose the SC80X825S when your application requires a force class around 2500 N at standard plant pressure. If you need more force, stepping up to the SC100 bore provides 3927 N push at 0.5 MPa; for a lighter, more compact solution, the SC63 bore delivers 1559 N. Always match replacement cylinders on five key points: bore (80 mm), stroke (825 mm), PT port thread, the built-in magnet (-S) for sensor compatibility, and the basic mounting style.
For this 825 mm stroke, be mindful of side loads. Long, unsupported piston rods are susceptible to bending under lateral force. If your load is not guided externally, consider adding an external linear guide or switching to a guided cylinder assembly to protect the rod bearings and ensure reliable service life.
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 SC80X825S 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 reaches 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
Yes. The -S suffix indicates a built-in magnet in the piston, making it fully compatible with AirTAC CMSG (reed) and DMSG/EMSG (solid-state) sensors. These sensors clamp directly onto the cylinder's tie-rods without needing additional brackets.
