About the Airtac SC80 Standard Cylinder SC80X620SLB
The AirTAC SC80X620SLB is an 80 mm bore, 620 mm stroke double-acting tie-rod cylinder delivering 2513 N push force at 0.5 MPa (4523 N at 0.9 MPa). Its 25 mm diameter piston rod and 28 mm adjustable air cushion provide smooth deceleration for mid-to-heavy linear motion tasks.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, plus an LB axial foot mount (F-SC80LB) for secure surface installation. The body length A is 182 mm, making the total extended length approximately 802 mm, well within the 1500 mm max standard stroke for bore 80.

Where the Airtac SC80 Standard Cylinder SC80X620SLB Is Used
Material Handling Pusher
The 620 mm stroke and 2513 N force at 0.5 MPa efficiently push boxes or totes off a conveyor line. The LB foot mount provides a rigid, fixed base for repetitive linear transfer.
Clamping & Assembly Fixtures
Delivers up to 4523 N of clamping force at 0.9 MPa for holding parts during welding or assembly. The built-in magnet allows sensors to confirm full extension and retraction for interlocked machine cycles.
Palletizing Lift Gate
Operates a lift gate or diverter arm in palletizing systems. The 28 mm adjustable cushion absorbs impact energy at the end of the 620 mm stroke, protecting the actuator and load.
Is the Airtac SC80 Standard Cylinder SC80X620SLB the Right Cylinder?
Choose the SC80 for its 2513 N push at 0.5 MPa—a significant step up from the 1559 N of a 63 mm bore. If your load exceeds 3500 N at 0.5 MPa, consider stepping up to the 100 mm bore (3927 N). For this 620 mm stroke, ensure side loads are minimal or use an external guide; the 25 mm rod can experience bending under unsupported lateral forces at long extensions.
For replacement, match five points: 80 mm bore, 620 mm stroke, PT1/4 port thread, LB foot mount (F-SC80LB), and the -S magnet for sensor compatibility. This SC tie-rod cylinder is not dimensionally interchangeable with ISO 15552 profiles.
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 SC80X620SLB FAQ
At 0.5 MPa, the push force is 2513 N and pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length (A=182 mm) than a typical ISO 15552 profile cylinder. It is not dimensionally interchangeable. Replace only with another AirTAC SC80 matching the stroke, PT port, LB mount, and -S magnet.
