About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX950-10S
The AirTAC SAIJ80X950-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers a robust 2513N push force at 0.5 MPa, equipped with a 25mm SUS420J2 stainless steel rod and a PT G3/8 port. The integrated magnet enables precise position detection using AirTAC CMSE reed or DMSE solid-state sensors.
This model provides a usable travel window of 940-950mm, allowing you to dial back the nominal 950mm stroke by up to 10mm during commissioning without adding external stops. It retains the standard extruded aluminum barrel with dual sensor grooves and utilizes a reduced mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2) compared to fixed-stroke variants.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX950-10S Is Used
Long-Stroke Component Pushing
Drives actuators across a 940-950mm window, allowing 10mm end-position tuning to accommodate varying workpiece sizes without mechanical rebuilds.
Transfer Line Diverter
Handles long linear diversion tasks on wide conveyors, using the adjustable stop to perfectly time the retract position for varying product widths.
Machine Commissioning Setup
Allows maintenance teams to fine-tune the exact end-of-stroke stopping point during initial setup, compensating for mechanical tolerance stack-ups over long travel distances.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX950-10S the Right Cylinder?
Choose this 80mm bore when an application requires higher thrust than a 63mm cylinder (1559N at 0.5 MPa) but less than a 100mm bore (3927N). The adjustable stroke is ideal for fine-tuning end positions on product changeovers, avoiding the need to physically swap cylinders. Because the 950mm stroke is long, the 25mm rod and M20x1.5 thread handle significant side loads, but an external guide is strongly recommended to prevent rod binding.
For drop-in replacements, match the 80mm bore, 950mm stroke, 10mm adjustment, PT G3/8 port, and SUS420J2 rod material. The -S magnet supports CMSE and DMSE switches. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider the SAIL or BSAI series instead.
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 SAIJ80AX950-10S FAQ
At 0.5 MPa it provides 2513N push and 2268N pull force. Operating speed ranges from 30 to 800 mm/s, supported by 36mm cushions at both ends.
The rear adjuster screw lets you shorten the effective travel from 950mm down to 940mm. It functions as a mechanical stop for end-position tuning, but it is not a lock and cannot hold the load without continuous air pressure.
