About the Airtac SAI50 Standard Cylinder SAI50X950
The AirTAC SAI50X950 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and a 950mm stroke. Because 950mm exceeds the standard maximum stroke of 1200mm for this bore, it is configured as a non-standard, made-to-order unit. It delivers a robust 982N of thrust at 0.5 MPa, making it well-suited for long-travel material handling and positioning tasks.
This model incorporates a standard carbon steel piston rod for structural rigidity and utilizes PT tapered port threads for a secure pneumatic connection. For environments requiring elevated thermal resistance, the seal stack can be upgraded from standard TPU to Viton (H) or NBR (N). The extruded aluminum barrel includes dual-side sensor grooves for straightforward position feedback integration.

Where the Airtac SAI50 Standard Cylinder SAI50X950 Is Used
Extended-Reach Transfer
Drives long-travel pallet shuttles and conveyor transfers where 950mm of smooth motion is required to bridge adjacent machinery.
Automated Warehousing
Positions lifting forks or pusher arms in high-bay storage systems, utilizing the 50mm bore's 982N force to displace goods reliably.
Long-Stroke Assembly
Actuates multi-stage tooling carriages over a broad working area, ensuring components are mated correctly over extended distances.
Is the Airtac SAI50 Standard Cylinder SAI50X950 the Right Cylinder?
Selecting the SAI50X950 is ideal when an application demands the 982N thrust class at 0.5 MPa but requires an extended 950mm travel distance. If your load requirements are lighter, stepping down to a 40mm bore yields 628N of push force, whereas upgrading to a 63mm bore provides 1559N for heavier payloads. Because this is a 950mm stroke, the unsupported rod is highly susceptible to bending under side loads; always utilize an external guide rail or a guided cylinder mechanism to prevent premature rod-bearing wear.
This cylinder mounts seamlessly via ISO 15552 interface dimensions, allowing direct interchangeability with other ISO 15552 profile cylinders. It uses a G1/4 port, an M16x1.5 rod thread, and can be paired with FA/FB flange or TC trunnion accessories. Note that a standard SAI does not sustain loads upon air loss; if your process requires 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 SAI50 Standard Cylinder SAI50X950 FAQ
The SAI50X950 provides a push force of 982N and a pull force of 825N at 0.5 MPa. At 0.7 MPa, the push force increases to 1374N.
Yes, the SAI50X950 is dimensionally interchangeable per ISO 15552 profile standards. You can drop it in to replace other ISO 15552 cylinders by matching the 50mm bore, 950mm stroke, and G1/4 port size.
