About the Airtac SC80 Standard Cylinder SC80X300LB
The SC80X300LB is an 80 mm bore, 300 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. It produces a push force of 2513 N at 0.5 MPa and can reach 4523 N at the maximum operating pressure of 0.9 MPa, making it a strong mid-range actuator for industrial linear motion.
This model is configured with an LB foot mount (accessory F-SC80LB) for secure surface installation. It features a 25 mm diameter piston rod, PT3/8 ports, and a 28 mm adjustable air cushion at each end to decelerate the piston smoothly. The standard TPU seals provide reliable operation from -20 to +70 C.

Where the Airtac SC80 Standard Cylinder SC80X300LB Is Used
Conveyor Diverter Gates
The 2513 N push force at 0.5 MPa and LB foot mount make this cylinder ideal for securely mounting beside a conveyor to actuate a heavy diverter gate or sorting paddle.
Industrial Press Feeders
With a 300 mm stroke and a robust 25 mm rod, it reliably pushes sheet metal or workpieces into a stamping press, with the adjustable cushion protecting tooling from impact damage.
Palletizing Lift Assist
Use the SC80X300LB in a low-level pallet dispenser or lift table. Its 4523 N maximum thrust at 0.9 MPa provides ample power for raising heavy pallet stacks in a fixed, foot-mounted position.
Is the Airtac SC80 Standard Cylinder SC80X300LB the Right Cylinder?
Choose the SC80 when the SC63's 1559 N push at 0.5 MPa is insufficient for the working load. If your application needs a higher force reserve, consider stepping up to the SC100 bore, which delivers 3927 N at the same pressure. Always match the bore, 300 mm stroke, PT3/8 port thread, LB foot mounting, and non-magnet configuration for a direct replacement.
For this 300 mm stroke, be mindful of side loads. An unsupported 25 mm rod extending 300 mm can bend under lateral force. Mitigate this risk by ensuring the load is guided on external rails or by using a rod-alignment coupler to prevent bearing wear and seal failure.
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 SC80X300LB 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.
It can replace another tie-rod cylinder only if all five key points match: 80 mm bore, 300 mm stroke, PT3/8 pneumatic ports, an LB-style foot mounting, and no magnet. The SC series is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
