About the Airtac SE80 Standard Cylinder SE80X250CB
The AirTAC SE80X250CB is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatics. It generates 2513 N of push force at 0.5 MPa and 3518 N at 0.7 MPa, utilizing an 80 mm bore and a 250 mm stroke. The CB mounting code equips this unit with a rear double clevis, allowing pivoting articulation to accommodate lateral movement during the drive cycle.
Its extruded aluminum barrel omits external tie rods, yielding a square, corrosion-resistant profile that mounts flush while exposing sensor grooves on three sides. Though this specific SKU lacks a position magnet, the end caps feature field-adjustable air cushioning at both ends, letting technicians dial in the exact needle setting to soften hard end stops at high velocities.

Where the Airtac SE80 Standard Cylinder SE80X250CB Is Used
Pallet Chain Diversion
Executes 250 mm extend strokes to push heavy timber pallets onto a perpendicular chain conveyor, utilizing the 2513 N push force to overcome sliding friction.
Corrugated Box Flap Folding
Drives a pivoting arm via the CB double clevis to fold large corrugated flaps on case erectors, absorbing high kinetic energy through the adjustable cushions.
Injection Mold Ejection
Provides the robust 3518 N extend force at 0.7 MPa required to knock out dense plastic injection molded parts from deep cavity molds.
Is the Airtac SE80 Standard Cylinder SE80X250CB the Right Cylinder?
If 2513 N of push at 0.5 MPa is excessive, dropping to the 63 mm bore yields 1559 N. Conversely, scaling up to the 100 mm bore provides 3927 N. This CB double-clevis mount is ideal for pivoting mechanisms, but remember that a plain SE cylinder drifts when air is exhausted or a valve centers; it cannot hold a load without live pressure, requiring a BSE rod lock for fail-safe holding. The 250 mm stroke operates at 30-800 mm/s, but long unsupported strokes increase rod-bearing bending; use an external guide to prevent side-load wear.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for CMSE/DMSE 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 (LB/FA/FB/CA/CB/CR/TC/FTC/TCM1/TCM2).
- check Installation by qualified personnel per AirTAC docs.
