Airtac SAIJ40 Adjustable Cylinder SAIJ40AX95-10
The AirTAC Airtac SAIJ40 Adjustable Cylinder SAIJ40AX95-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 95mm stroke, G1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ40 Adjustable Cylinder SAIJ40AX95-10
The AirTAC SAIJ40X95-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 628N push force at 0.5 MPa and uses a 16mm SUS420J2 stainless steel rod with an M12x1.25 thread. By turning the rear screw, you can trim the effective travel back by up to 10mm, creating an 85-95mm usable window for precise end-position tuning.
This bore size features a G1/4 port and achieves speeds of 30-800mm/s. The extruded aluminum barrel includes sensor grooves on both sides. Because this configuration lacks the -S magnet option, it requires external mounting of CMSE reed or DMSE electronic switches rather than integrated slot sensing. The adjuster acts purely as a travel stop and does not lock the load without live air pressure.

Where the Airtac SAIJ40 Adjustable Cylinder SAIJ40AX95-10 Is Used
End-Stop Tuning
Dial in the exact 85-95mm retract position during machine commissioning to perfect a pick-and-place motion without adding external hard stops.
Product Changeover
Quickly adjust the stroke by up to 10mm on a packaging line when switching to a slightly different carton size, minimizing downtime.
Fixture Alignment
Micro-adjust the clamping reach on a machining fixture to accommodate part tolerances, relying on the 628N force to secure the workpiece.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40AX95-10 the Right Cylinder?
Choose this 40mm bore when an application demands 628N of push force at 0.5 MPa, stepping up from a 32mm bore (402N) or down from a 63mm bore (1559N). The 10mm adjustable window is ideal for fine-tuning retract positions during commissioning or product changeover without swapping cylinders. For fixed-position tasks without variation, a standard SAI cylinder is sufficient. To replace this unit, match the 40mm bore, 95mm stroke, PT tapered port thread, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).

- ✓ 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 SAIJ40AX95-10 FAQ
At 0.5 MPa, this 40mm bore cylinder provides 628N of push force and 528N of pull force. If operated at 0.7 MPa, the push force increases to 879N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 95mm nominal stroke by up to 10mm. This creates an 85-95mm travel window for fine-tuning, though it does not lock the load without continuous air pressure.
