About the Airtac SAI80 Standard Air Cylinder SAI80X135
The AirTAC SAI80X135 is a double-acting ISO 15552 profile cylinder featuring an 80mm bore and a 135mm stroke. It delivers a robust 2513N of push force and 2268N of pull force at 0.5 MPa, making it well-suited for medium-to-heavy duty actuation where substantial thrust is required over a compact mid-range distance.
This model features a standard carbon steel piston rod and utilizes a PT tapered port thread. The extruded aluminum barrel includes integrated sensor grooves on both sides, allowing for direct mounting of CMSE or DMSE series switches if position feedback is required in your automation cell.

Where the Airtac SAI80 Standard Air Cylinder SAI80X135 Is Used
Heavy-Duty Clamping
Provides 2513N of thrust at 0.5 MPa to securely hold heavy metal workpieces during machining or welding operations.
Material Diverting
Actuates robust routing gates on high-throughput conveyor lines, moving heavy packaged goods or automotive parts.
Press Fit Assembly
Delivers the precise force needed to press bearings or pins into housings over a compact 135mm travel distance.
Is the Airtac SAI80 Standard Air Cylinder SAI80X135 the Right Cylinder?
Select this 80mm bore when an application demands roughly 2500N of thrust at 0.5 MPa, bridging the gap between the 63mm bore (1559N push) and the 100mm bore (3927N push). Its 135mm stroke is a custom intermediate length, ideal for assemblies needing exact travel without the extra length of a standard 150mm stroke.
As an ISO 15552 profile cylinder, it serves as a dimensionally interchangeable drop-in replacement for other standard cylinders in existing machine designs. Because this is a double-acting cylinder, it relies entirely on continuous air pressure for movement; it will not hold a load if air pressure is lost or exhausted. For position holding without live pressure, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants.
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 SAI80 Standard Air Cylinder SAI80X135 FAQ
At 0.5 MPa, the SAI80X135 cylinder provides 2513N of push force and 2268N of pull force. At the maximum operating pressure of 1.0 MPa, it can deliver up to 513 kgf of theoretical force.
Yes, the SAI80X135 is a genuine ISO 15552 profile cylinder. Its standardized mounting dimensions make it a drop-in replacement for other ISO 15552 cylinders, provided you match the 80mm bore, 135mm stroke, and mounting accessories.
