About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X190-10S
The AirTAC SAIJ80X190-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 2513N of push force at 0.5MPa and features a 10mm adjustment range, creating a 180-190mm usable travel window for precise end-position tuning. The carbon steel rod uses an M20x1.5 thread, and the -S variant includes a magnet for CMSE reed and DMSE electronic sensors.
This extruded aluminum barrel design omits the FB, CA, CB, and CR mounts, utilizing a focused mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2. The rear screw acts as a travel stop to dial in the retract position during commissioning without adding external stops, though it does not lock the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X190-10S Is Used
Machine Setup Calibration
Dial in the exact 180-190mm retract position during initial commissioning to perfectly align a gripping jaw without machining external spacers.
Product Size Changeover
Quickly adapt the end-stop for a new part length on a packaging line by turning the rear screw, saving minutes of retooling time per shift.
Variable End Positioning
Fine-tune the final resting point of a heavy 2513N push assembly, ensuring precise mechanical contact without overtraveling the stroke.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X190-10S the Right Cylinder?
Choose this 80mm bore when a 50mm bore (982N push at 0.5MPa) lacks the power for heavier payloads, but a 100mm bore (3927N at 0.5MPa) is physically oversized. The 10mm adjustment window is ideal for product changeovers requiring slight retract position shifts, avoiding the need to swap out a fixed-stroke SAI cylinder. For load-holding without live air, select an SAIL or BSAI cylinder instead, as this adjuster is strictly a stop.
This model uses a PT tapered port and operates at 30-800mm/s. Because the 190mm stroke is under 300mm, side-load stress is moderate, but the 25mm rod and M20x1.5 thread still provide robust resistance to deflection. It is dimensionally interchangeable per ISO 15552 standards.
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 SAIJ80X190-10S FAQ
At 0.5MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. It can reach up to 4523N push at 0.9MPa.
The rear adjuster screw lets you shorten the 190mm nominal stroke by up to 10mm, providing a 180-190mm travel window. It functions as a mechanical stop for end-position tuning and requires live air to hold the load.
