About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX950-10S
The AirTAC SAIJ80X950-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 940-950 mm usable travel window, letting you dial back the 950 mm nominal stroke by up to 10 mm during commissioning. In the 80 mm bore class, it generates 2513 N of pull force at 0.5 MPa, giving it strong push and pull capacity for heavy positioning tasks.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a piston magnet for position sensing. It is compatible with AirTAC CMSE reed switches and DMSE solid-state sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the PT tapered port threads ensure a reliable pneumatic connection.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX950-10S Is Used
Machine Setup Tuning
Fine-tune the 940-950 mm retract end-stop during initial machine commissioning to dial in exact positioning without machining custom spacers.
Product Changeover
Quickly adjust the stroke by up to 10 mm on a packaging line when switching to a different product size, minimizing downtime.
Heavy Material Handling
Leverage the 2513 N pull force at 0.5 MPa to push or position heavy pallets and fixtures along a guided linear path.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX950-10S the Right Cylinder?
Choose this 80 mm bore when you need more force than a 63 mm cylinder (which provides 1402 N pull at 0.5 MPa) but want to avoid the larger footprint of a 100 mm unit. The adjustable stroke is ideal for product changeovers, allowing you to fine-tune the retract end position without swapping the cylinder or adding external stops. At 950 mm, this stroke length requires careful handling of side loads; an external guide is recommended to prevent rod binding and premature seal wear.
The rear adjuster acts solely as a mechanical stop and does not hold the load without live air pressure. If your application requires fail-safe load holding, select an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder instead. For ISO 15552 interchangeability, match the 80 mm bore, 950 mm stroke, 10 mm adjuster, PT port, and -S magnet, choosing from Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts.
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 SAIJ80 Adjustable Cylinder SAIJ80BX950-10S FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke by up to 10 mm, providing a 940-950 mm travel window. It only sets the travel end and does not lock or hold the load without continuous air pressure.
At 0.5 MPa, this 80 mm bore cylinder provides 2513 N of pull force and 3518 N of push force. It operates at speeds between 30-800 mm/s.
