About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX700-50S
The AirTAC SAIJ32X700-50-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 402N push force at 0.5 MPa and uses a 12mm SUS420J2 stainless steel rod. The built-in rear stopper allows you to dial back the 700mm nominal stroke by up to 50mm, creating a precise 650-700mm usable travel window for fine-tuning end positions during commissioning.
This unit includes a magnet for position sensing, working seamlessly with AirTAC CMSE reed and DMSE electronic sensors. It features PT tapered ports sized G1/8 and a 27mm air cushion at both ends. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting options cover Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX700-50S Is Used
End-Position Tuning
Dial in the exact 650-700mm travel distance during machine setup without machining hard stops.
Product Changeover
Quickly adjust the retract end-stop on a packaging line when running different package lengths.
Automated Assembly
Provides precise extend positioning for lightweight 32mm bore automation tasks.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX700-50S the Right Cylinder?
Choose this adjustable SAIJ model over a fixed-stroke SAI cylinder when your application requires variable end-stops or frequent product changeovers without physically swapping the cylinder. The 32mm bore delivers 402N of push force at 0.5 MPa; stepping up to a 40mm bore increases that to 628N if your payload requires more thrust. Because this cylinder lacks a lock mechanism, it cannot hold position without live air—the rear adjuster is strictly a travel stop, not a brake. For load-holding without pressure, consider a SAIL or BSAI cylinder.
At 700mm of stroke, the 12mm rod is highly susceptible to side-loading and buckling; an external guide rail is strongly recommended to prevent premature seal wear. To replace an ISO 15552 cylinder, match the 32mm bore, 700mm stroke, 50mm adjustment, G1/8 PT ports, and the -S magnet.
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 Adjustable Cylinder SAIJ32 SAIJ32AX700-50S FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. The maximum thrust is 82 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that shortens the 700mm nominal stroke by up to 50mm, giving a usable travel window of 650-700mm. It only sets the end position and does not lock or hold the load without air pressure.
