About the Airtac SC80 Standard Cylinder SC80X690S
The AirTAC SC80X690S is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa and up to 4523 N at 0.9 MPa. With an 80 mm bore and a 25 mm diameter piston rod, this model provides a 690 mm stroke and features an adjustable air cushion (28 mm length) to decelerate end-of-stroke impact, protecting your equipment.
The integrated magnet (suffix -S) allows direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors on the tie-rod barrel for reliable, non-contact position sensing. Its PT3/8 port threads and M20x1.5 rod thread are standard, and the total body length is 182 mm plus stroke, making it a compact choice for automation tasks requiring mid-range force and feedback.

Where the Airtac SC80 Standard Cylinder SC80X690S Is Used
Material Handling Pushers
The 2513 N push force at 0.5 MPa easily moves boxes or totes off a conveyor line, with the 690 mm stroke providing ample reach across wide belt sections.
Automated Clamping Fixtures
Use the built-in magnet and CMSG sensors to confirm clamp position in CNC welding jigs, ensuring the part is secured before the cycle starts.
Palletizing Lift Gates
Controls a vertical stop gate at the end of a gravity roller conveyor. The adjustable cushion provides a soft stop, preventing pallet damage during high-cycle operation.
Is the Airtac SC80 Standard Cylinder SC80X690S the Right Cylinder?
For applications requiring slightly less force, the 63 mm bore SC63 series provides 1559 N at 0.5 MPa. If you need higher thrust, step up to the 100 mm bore SC100 series, which offers 3927 N at the same pressure. This 80 mm bore model is a balanced mid-range actuator for general automation.
At 690 mm of stroke, the unsupported piston rod is subject to bending under side loads. Always guide the load externally with a linear rail or rod guide to prevent premature bearing wear and seal failure. When replacing an existing cylinder, match five key points: 80 mm bore, 690 mm stroke, PT3/8 port thread, the built-in magnet (-S) for sensor compatibility, and the basic mounting style.
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 SC80X690S FAQ
At the standard operating pressure of 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 at 1.0 MPa is 513 kgf.
Yes. The -S suffix in the model code SC80X690S indicates a built-in magnet on the piston. This allows you to clamp AirTAC CMSG, DMSG, or EMSG sensors directly onto the cylinder's tie-rod barrel to detect piston position without additional brackets.
