About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX200-40S
The AirTAC SAIJ32X200-40-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, designed to fine-tune the end position at commissioning without swapping hardware. It features a 12mm carbon steel rod and a PT tapered G1/8 port, delivering 402N of push force at 0.5 MPa. With a 200mm nominal stroke and a 40mm adjustment range, the usable travel window is 160-200mm.
This variant includes an -S magnet for position sensing with AirTAC CMSE (reed) or DMSE (solid-state) switches, fitting directly into the dual-side sensor grooves on the extruded aluminum barrel. The rod is constructed from SUS420J2 stainless steel (code A), offering enhanced corrosion resistance. The rear adjuster acts purely as a travel stop and cannot hold a load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX200-40S Is Used
Product Changeovers
Dial in the 160-200mm travel window during format changes on packaging lines, avoiding physical cylinder swaps.
End-Stop Tuning
Fine-tune the retract end-position at commissioning to dial out mechanical play without adding external stops.
Sorting Diverters
Adjust the actuation distance on the fly to handle varying package sizes on a single sorting conveyor line.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX200-40S the Right Cylinder?
Choose this 32mm bore when an application requires 402N of push force at 0.5 MPa, or step up to the 40mm bore if you need 628N. The adjustable stroke is selected over a fixed SAI cylinder when machine setups require variable end-stops or product-size changeovers, allowing 160-200mm of travel tuning. For holding loads without live air, use a SAIL or BSAI cylinder instead, as the SAIJ adjuster is only a stop.
For ISO 15552 replacement matching, specify: 32mm bore, 200mm stroke, 40mm adjustment, PT port threads, SUS420J2 rod material, and a magnet for CMSE/DMSE sensors. Since the 200mm stroke is relatively long for the 12mm rod, an external guide is recommended to prevent excessive side-loading. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 Adjustable Cylinder SAIJ32 SAIJ32AX200-40S FAQ
The rear adjuster screw lets you shorten the 200mm nominal stroke by up to 40mm, providing a usable travel window of 160-200mm to fine-tune the retract end position.
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At 0.7 MPa, the push force increases to 563N.
