About the Airtac SAI63 Standard Cylinder SAI63X1150STC
The AirTAC SAI63X1150-S is a double-acting ISO 15552 profile cylinder engineered for long-distance linear actuation. Delivering a push force of 1559 N at 0.5 MPa, this unit pairs a 63 mm bore with a 1150 mm stroke to bridge the gap between standard reach and extended travel requirements.
This configuration includes a built-in magnet for seamless integration with CMSE and DMSE sensor switches, which seat directly into the dual grooves on the extruded aluminum barrel. The piston rod utilizes standard carbon steel for high tensile strength, while the adjustable air cushions at both ends absorb kinetic energy to protect the end caps.

Where the Airtac SAI63 Standard Cylinder SAI63X1150STC Is Used
Long-Stroke Material Push
Pushes workpieces or pallets along extended conveyor sections where a 1150 mm reach is required to bridge machine gaps.
High-Bay Ejection
Ejects packaged goods from elevated storage tiers, utilizing the 1559 N push force to overcome friction over a long linear path.
Transfer Arm Actuation
Drives horizontal transfer arms in automated assembly lines, relying on external guides to maintain rod alignment over the 1.15 meter travel.
Is the Airtac SAI63 Standard Cylinder SAI63X1150STC the Right Cylinder?
Because this 1150 mm stroke approaches the 1500 mm maximum standard limit for the 63 mm bore, side load management is critical. An unsupported rod of this length is highly susceptible to bending under lateral stress; always pair this cylinder with external linear guides or a guided cylinder carriage to prevent premature rod-bearing wear.
If your application requires less reach, stepping down to a 50 mm bore offers a 982 N push force at 0.5 MPa, while upgrading to an 80 mm bore yields 2513 N. This TC trunnion-mounted variant with PT tapered ports provides direct dimensional interchangeability with other ISO 15552 cylinders. Remember that standard air cushions only decelerate the piston; they cannot hold a load vertically if air pressure drops. For dead-load holding, specify an external pilot check valve or the SAIL locking variant.
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 SAI63 Standard Cylinder SAI63X1150STC FAQ
