About the Airtac SAI50 Standard Cylinder SAI50BX1000
The AirTAC SAI50X1000 is a double-acting ISO 15552 profile cylinder engineered for long-distance linear actuation. It provides a push force of 982 N and a pull force of 825 N at 0.5 MPa, making it well-suited for moving moderate loads over its 1000 mm stroke. The extruded aluminum barrel design omits tie-rods, presenting a clean exterior that drops directly into standard ISO 15552 mounting interfaces.
Built to exacting specifications, this unit incorporates a SUS304 stainless steel rod for superior corrosion resistance in humid or washdown environments. Fluid supply is routed through PT tapered ports. While this specific configuration lacks a magnet for position sensing, the barrel retains dual-side sensor grooves, allowing future integration of CMSE or DMSE switches if a magnetic piston is later required.

Where the Airtac SAI50 Standard Cylinder SAI50BX1000 Is Used
Long-Stroke Material Transfer
Pushes products or pallets between distant workstations on a 1000 mm linear path, utilizing the 982 N push force to overcome friction over extended guide rails.
High-Bay Shuttle Extraction
Extracts totes or cartons from deep storage lanes where a full meter of actuation is required, benefiting from the SUS304 rod in varying humidity levels.
Automated Door Actuation
Opens and closes large industrial partition doors or safety gates, relying on the adjustable air cushions to soften the impact at the fully open and closed positions.
Is the Airtac SAI50 Standard Cylinder SAI50BX1000 the Right Cylinder?
Selecting this 50 mm bore over a smaller 40 mm option increases your 0.5 MPa push thrust from 628 N to 982 N, providing extra power for longer travel demands. Conversely, stepping up to a 63 mm bore yields 1559 N if your payload exceeds the 50 mm capacity. Because this model features a 1000 mm stroke, the extended rod is highly susceptible to bending under side loads; always utilize an external linear guide or a guided cylinder carriage to prevent premature rod-bearing wear.
This profile cylinder is dimensionally interchangeable per ISO 15552, ensuring seamless replacement compatibility with other standard cylinders sharing the same 50 mm bore, 1000 mm stroke, and PT port footprint. Note that the adjustable air cushions only decelerate the piston at stroke ends; they do not lock the load. If your application requires position holding upon loss of air pressure, consider the SAIL variant with an air-released lock or an external pilot-operated check valve.
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 SAI50BX1000 FAQ
At an operating pressure of 0.5 MPa, this 50 mm bore cylinder generates a push force of 982 N and a pull force of 825 N. If pressure is increased to 0.7 MPa, the push force reaches 1374 N.
Yes, the SAI50X1000 is a true ISO 15552 profile cylinder. Its standardized mounting dimensions, 50 mm bore, 1000 mm stroke, and PT port locations make it dimensionally interchangeable with other ISO 15552 standard cylinders.
