Airtac SAIJ40 Adjustable Cylinder SAIJ40AX60-30
The AirTAC SAIJ40 Adjustable Cylinder SAIJ40AX60-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 60mm stroke, G1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ40 Adjustable Cylinder SAIJ40AX60-30
The AirTAC SAIJ40X60-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down from a 60 mm nominal stroke to a 30 mm minimum. This creates a highly flexible 30-60 mm usable window, ideal for dialing in exact end positions during machine commissioning without swapping hardware.
Built with a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance, this model uses PT tapered ports and operates at speeds between 30 and 800 mm/s. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to add CMSE reed or DMSE electronic switches later if position feedback becomes necessary.

Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 528 N | 528 N |
| 0.7 MPa | 739 N | — |
| Max (@1.0 MPa) | 108 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ40 Adjustable Cylinder SAIJ40AX60-30 Is Used
Machine Commissioning
Dial in the exact clamping reach on a new fixture by trimming the stroke from 60 mm down to 45 mm, avoiding the need to machine custom spacers.
Product Changeover
Quickly adapt a packaging line to different carton depths by adjusting the rear stopper within the 30-60 mm window during shift transitions.
Prototype Tooling
Validate pick-and-place kinematics on a 40 mm bore actuator when the final part dimensions are still under development.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40AX60-30 the Right Cylinder?
Selecting this 40 mm bore over a smaller 32 mm variant steps your thrust up from 402 N to 628 N at 0.5 MPa, whereas stepping up to a 50 mm bore would yield 982 N. The 30 mm adjustment range is exceptionally wide for a 60 mm stroke, giving you half the total travel to trim back via the rear stopper screw. This is perfect for prototyping or product-size changeovers where the exact reach is unknown.
Because this is a standard SAIJ and not a locking variant, the rear adjuster functions purely as a mechanical travel stop and cannot hold a load without continuous live air pressure. For dead-load holding, consider the SAIL or BSAI series. When replacing an ISO 15552 cylinder, match the 40 mm bore, 60 mm stroke, PT port thread, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), which omits FB, CA, CB, and CR brackets.
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 SAIJ40 Adjustable Cylinder SAIJ40AX60-30 FAQ
If you increase pressure to 0.7 MPa, the push force rises to 879 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from its 60 mm nominal stroke down to as little as 30 mm. It only sets the end position and does not lock the load without live air pressure.
