The AirTAC SAIJ40 Adjustable Cylinder SAIJ40AX45-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 45mm 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.
The AirTAC SAIJ40X45-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 35-45 mm, allowing you to dial back the 45 mm nominal stroke by up to 10 mm during machine setup.
This variant uses a SUS420J2 stainless steel rod for superior corrosion resistance and features PT tapered port threading. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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.

Dial in the exact 35 to 45 mm travel distance during commissioning to perfect a delicate pressing or forming operation without mechanical rework.
Quickly adapt the cylinder's stroke limit on a packaging line when switching to a different carton size, saving valuable setup time.
Use the 10 mm adjustment range to set precise contact points for delicate component placement, preventing overtravel damage.
The adjustable stroke is ideal for product changeovers, letting you fine-tune the end position without swapping cylinders or adding external stops. Because the rear adjuster acts only as a travel stop and not a lock, you must maintain live air to hold a load; for fail-safe holding, consider the SAIL or BSAI series. To match ISO 15552 interchangeability, verify the 45 mm stroke, 10 mm adjustment, PT G1/4 port, and specific mounting accessories.
Quick checklist
At the maximum 1.0 MPa pressure, it can generate up to 128 kgf.
The rear adjuster screw acts as a mechanical stop that shortens the effective travel from the 45 mm nominal stroke down to as little as 35 mm. It allows fine-tuning of the retract end position without replacing the cylinder.
