About the Airtac SC80 Standard Cylinder SC80X850LB
The SC80X850LB is an 80 mm bore double-acting pneumatic cylinder with an 850 mm stroke, delivering a push force of 2513 N at 0.5 MPa (up to 4523 N at 0.9 MPa). The 25 mm diameter piston rod and 28 mm adjustable air cushion provide smooth deceleration for mid-to-long stroke linear moves.
This model is configured with LB axial foot mounts (F-SC80LB) for rigid surface mounting along the barrel. It uses standard PT ports, TPU seals for a -20 to +70 °C operating range, and accepts the full range of SC mounting accessories.

Where the Airtac SC80 Standard Cylinder SC80X850LB Is Used
Conveyor Gate Actuation
The 850 mm stroke and 2513 N push force at 0.5 MPa operate diverter gates or stops on wide conveyor lines, with the LB foot mount providing stable, fixed-position anchoring.
Pallet Transfer Systems
Moves pallets between roller beds in automated warehouses. The 80 mm bore supplies ample force to shift heavy loads, while the adjustable cushion protects the cylinder at end-of-stroke.
Press-Feed Ejectors
Ejects formed parts from stamping or injection-molding stations. The long 850 mm reach clears large tooling, and the foot mount withstands repetitive impact forces when properly aligned.
Is the Airtac SC80 Standard Cylinder SC80X850LB the Right Cylinder?
Choose the SC80 for its 2513 N push force at 0.5 MPa—a step up from the SC63 (1559 N) for heavier tooling, and below the SC100 (3927 N) for space-constrained designs. For this 850 mm stroke, ensure the rod is guided externally if side loads are present; long unsupported rods are susceptible to bending under lateral force.
For a direct replacement, match bore (80 mm), stroke (850 mm), port thread (PT), mounting accessory (LB foot), and magnet option (none). The SC series is a tie-rod cylinder, shorter than ISO 15552 profiles, so interchangeability is limited to another AirTAC SC80 of identical 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 SC80X850LB FAQ
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At 0.7 MPa, push force increases to 3518 N. The maximum operating push force at 0.9 MPa is 4523 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length (A=182 mm for bore 80) than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. Use it to replace another AirTAC SC80 with matching bore, stroke, port thread, and LB foot mount.
