About the Airtac SC80 Standard Cylinder SC80X650SLB
The SC80X650SLB delivers a robust 2513 N of push force at 0.5 MPa, scaling to 4523 N at 0.9 MPa, making it a strong mid-range actuator for industrial linear motion. With a 25 mm diameter rod and a 28 mm air cushion, this double-acting cylinder is built to handle substantial loads while providing smooth, adjustable end-of-stroke deceleration.
This model features a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for precise, contactless position feedback. The LB foot mount (F-SC80LB) provides a stable, surface-mounted installation, ideal for linear transfer and pressing applications where the cylinder body needs rigid axial support.

Where the Airtac SC80 Standard Cylinder SC80X650SLB Is Used
Part Transfer
The 650 mm stroke and 2513 N push force efficiently shuttle components between conveyor lines or workstations in automated assembly cells.
Clamping & Pressing
With 4523 N of force at 0.9 MPa, this cylinder is well-suited for pneumatic clamping fixtures and light-duty press-fit operations requiring a long travel.
Material Handling
The LB foot mount and magnetic piston enable reliable pallet stops or diverter gates in logistics systems, with sensor feedback confirming position.
Is the Airtac SC80 Standard Cylinder SC80X650SLB the Right Cylinder?
The SC80 sits between the SC63 (1559 N push at 0.5 MPa) and the SC100 (3927 N push at 0.5 MPa). If your load requires more than 2513 N of force, stepping up to the 100 mm bore provides a significant power increase. For this 650 mm stroke, ensure the load is guided externally or use a guided cylinder if significant side forces are present, as the extended 25 mm rod can be vulnerable to bending under lateral loads.
For a direct replacement, match these five points: 80 mm bore, 650 mm stroke, PT port thread, LB foot mounting, and the -S magnet for sensor compatibility. This is a genuine AirTAC tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to another AirTAC SC80 with the same 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 SC80 Standard Cylinder SC80X650SLB FAQ
At the standard operating pressure of 0.7 MPa, the push force is 3518 N and the pull force is 3175 N. The maximum push force at 0.9 MPa is 4523 N. Always apply a safety factor for dynamic loads.
Yes. The -S suffix indicates a built-in magnet on the piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder's tie-rod barrel to detect piston position without additional brackets.
