About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX300-75
The AirTAC SAIJ80X300-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 225 to 300 mm, allowing you to dial back the nominal 300 mm stroke by up to 75 mm during commissioning. This bore delivers substantial thrust, offering 2513 N pull and 3518 N push at 0.7 MPa.
The piston rod is equipped with a 25 mm diameter and an M20x1.5 thread, machined from SUS420J2 stainless steel for robust corrosion resistance. It uses PT tapered ports sized G3/8 and achieves variable air cushioning over 36 mm at both ends. The extruded aluminum barrel includes dual-side sensor grooves, ready for flush mounting of CMSE or DMSE switches if a magnet is added later.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX300-75 Is Used
Variable End-Stop Tuning
Perfect for automated lines where the retract position must be shifted by up to 75 mm to accommodate different material thicknesses without swapping cylinders.
Machine Changeover
Speeds up product family changeovers by letting operators dial in the 225 to 300 mm travel window directly at the rear adjustment screw.
Heavy Payload Positioning
Handles robust clamping or lifting tasks requiring up to 2513 N of pull force, using the adjuster to fine-tune the final resting position.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX300-75 the Right Cylinder?
Select this 80 mm bore when your application requires high force but exact end-positioning varies by product size. If you need less force, stepping down to a 63 mm bore yields 1402 N pull at 0.5 MPa, whereas a 100 mm bore offers 3681 N pull if your payload grows. Choose this adjustable SAIJ over a fixed-stroke SAI to fine-tune the retract stop without adding external physical spacers. Since the stroke is 300 mm, ensure you use an external guide to prevent rod side-loading and premature seal wear.
For ISO 15552 dimensional interchangeability, match the 80 mm bore, 300 mm nominal stroke, 75 mm adjustment range, PT G3/8 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that this cylinder does not hold position without live air; the rear screw is a travel stop, not a lock. For fail-safe load holding, consider an AirTAC SAIL or BSAI series.

- ✓ 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 SAIJ80AX300-75 FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from 300 mm down to 225 mm. It trims the retract end-position at commissioning without requiring external stops, though it does not lock the load without live air pressure.
At 0.5 MPa it provides 2513 N pull and 2268 N push. At 0.7 MPa the push force increases to 3518 N. The cylinder operates at speeds of 30 to 800 mm/s.
