About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X90-20
The AirTAC SAIJ80X90-20 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features an 80mm bore generating 2513N of push force at 0.5MPa, paired with a 90mm nominal stroke that can be precisely dialed back by up to 20mm. This yields a 70-90mm usable travel window, allowing you to fine-tune the retract end position during commissioning without adding external stops.
The extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch mounting. It uses a G3/8 port and a robust 25mm carbon steel rod with an M20x1.5 thread, providing excellent resistance to side loads. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR configurations.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X90-20 Is Used
End-Position Tuning
Dial in the exact 70-90mm retract distance during machine setup to perfect product seating without machining custom spacers.
Product Changeovers
Quickly adjust the stroke by up to 20mm on a packaging line to accommodate different carton sizes on the fly.
Assembly Clamping
Leverage the 2513N push force at 0.5MPa to secure heavy components, using the adjuster to prevent over-travel.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X90-20 the Right Cylinder?
Choose this 80mm bore if your application requires roughly 2513N push force at 0.5MPa, stepping up from a 63mm bore (1559N) or down from a 100mm bore (3927N). The adjustable 70-90mm travel window is ideal for product-size changeovers on a packaging line, replacing the need to swap out a fixed-stroke SAI cylinder. The 25mm rod and M20x1.5 thread handle high mechanical stress well.
Remember that the rear adjuster functions strictly as a travel stop, not a locking device; the cylinder cannot hold a load without live air pressure. For fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder. When replacing an ISO 15552 unit, match the 80mm bore, 90mm stroke, 20mm adjustment, PT port thread, and mounting style. This unit omits the -S magnet, so it requires external sensors if position detection is needed.
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 SAIJ80X90-20 FAQ
At 0.5MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. It can reach a maximum push force of 4523N at 0.9MPa.
The rear adjuster acts as a mechanical stop that shortens the 90mm nominal stroke by up to 20mm, creating a 70-90mm usable travel window. It only sets the end position and does not lock the load without air pressure.
