About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X180-30
The AirTAC SAIJ80X180-30 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 180 mm travel that can be dialed back by up to 30 mm, creating a precise 150-180 mm usable window for commissioning without external stops. In this bore size, it generates 2513 N of push force and 2268 N of pull force at 0.5 MPa.
The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. The carbon steel rod uses an M20x1.5 thread, and the cylinder accepts PT tapered ports. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options found on some other series.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X180-30 Is Used
Machine Changeover
Dial in the 150-180 mm travel window during product size changes to set new end positions rapidly without machining new external stop blocks.
End-Position Tuning
Fine-tune the retract stroke by up to 30 mm at commissioning to dial in exact clamping or pressing distances on the production line.
Assembly Station Setup
Use the 2513 N push force to seat components, relying on the rear screw to adjust the final resting position for different assembly heights.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X180-30 the Right Cylinder?
Choose this 80 mm bore when your application requires over 2200 N of pull force at 0.5 MPa but less than the 3927 N push force of a 100 mm bore. The adjustable stroke is ideal for machine changeovers, letting you fine-tune the retract end position without swapping cylinders. For holding loads without live air pressure, select a SAIL or BSAI series cylinder instead, as the rear adjuster here is a stop, not a lock. When matching ISO 15552 replacements, confirm the 180 mm stroke, 30 mm adjustment, PT port thread, and mounting style.
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 SAIJ80X180-30 FAQ
At 0.5 MPa, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. It operates at speeds between 30 and 800 mm/s.
The rear adjuster screw acts as a mechanical stop that shortens the 180 mm nominal stroke by up to 30 mm, giving a usable travel window of 150 to 180 mm. It only sets the end position and does not lock the load without live air.
