About the Airtac SC80 Standard Cylinder SC80X850SLB
The AirTAC SC80X850SLB is a double-acting single-rod pneumatic cylinder with an 80 mm bore and an 850 mm stroke, delivering a push force of 2513 N at 0.5 MPa (4523 N at the maximum operating pressure of 0.9 MPa). The piston rod is 25 mm in diameter with an M20x1.5 male thread, and the cylinder features a 28 mm adjustable air cushion at each end to decelerate the piston smoothly, reducing impact noise and vibration.
This model includes a built-in magnet (-S suffix), allowing easy mounting of CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the tie-rod barrel for non-contact position sensing. The LB suffix indicates it is supplied with F-SC80LB axial foot mounts for secure surface installation. With a body length of 182 mm, the total extended length is approximately 1032 mm.

Where the Airtac SC80 Standard Cylinder SC80X850SLB Is Used
Material Transfer Gates
The 850 mm stroke and 2513 N push force at 0.5 MPa efficiently actuate diverter gates on wide conveyor lines, with the LB foot mount providing a stable base and the built-in magnet enabling end-of-stroke confirmation.
Sawmill Log Stops
Delivering up to 4523 N of force at 0.9 MPa, this cylinder reliably stops and positions heavy logs on processing decks. The adjustable cushion absorbs the high kinetic energy of the moving load for a controlled, soft stop.
Automated Welding Fixtures
The long 850 mm stroke clamps large fabricated assemblies. Magnetic sensors on the tie-rod barrel provide precise open/closed position feedback to the PLC, ensuring the fixture is fully engaged before the welding cycle starts.
Is the Airtac SC80 Standard Cylinder SC80X850SLB the Right Cylinder?
Select the SC80 bore when your application requires a push force between 2513 N and 4523 N. If your force requirement is lower, stepping down to a 63 mm bore reduces the push force to 1559 N at 0.5 MPa, saving energy and space. For higher demands, the 100 mm bore provides 3927 N at the same pressure. For this 850 mm stroke, ensure the load is guided externally if side forces are present; the long unsupported 25 mm rod can bend under lateral loads, causing premature seal and bearing wear.
To replace an existing cylinder, match five key points: the 80 mm bore, the 850 mm stroke, the PT1/8 port thread, the LB foot mounting accessory, and the built-in magnet for sensor compatibility. This tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard.
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 SC80X850SLB FAQ
At the standard 0.5 MPa operating pressure, 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 with a shorter overall body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC80 tie-rod cylinder with matching stroke, PT ports, LB foot mount, and a built-in magnet.
