About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX600-50S
The AirTAC SAIJ32X600-50-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 600 mm nominal stroke that can be fine-tuned backward by up to 50 mm, yielding a usable travel window of 550 to 600 mm. Delivering 402 Newtons of push force at 0.5 MPa, it is built with a SUS420J2 stainless steel rod and includes a magnet for position sensing.
This model uses PT tapered port threads (G1/8) and operates at speeds between 30 and 800 mm/s. The rear adjuster acts purely as a mechanical stop to dial in end positions during commissioning. For load-holding without live air pressure, an external rod lock or a related SAIL pneumatic lock cylinder is required, as the adjuster itself does not function as a brake.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX600-50S Is Used
Machine Changeover
Dial in the 550-600 mm stroke window during product size changes without adding external stopper blocks to the machine frame.
End-Position Tuning
Fine-tune the retract end position at commissioning to achieve precise mechanical alignment using the rear adjustment screw.
Variable End Stops
Accommodate varying product lengths on a conveyor line by adjusting the effective stroke up to 50 mm on the fly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX600-50S the Right Cylinder?
Choose this 32 mm bore when an application requires precise end-position tuning without swapping cylinders, offering a 550-600 mm adjustable travel window. If your setup needs greater thrust, stepping up to the 40 mm bore increases push force to 628 Newtons at 0.5 MPa. Because this cylinder features a 600 mm stroke, the 12 mm rod diameter requires external guidance to prevent excessive side-loading and premature seal wear.
This adjustable-stroke variant is selected over a fixed SAI cylinder when machine changeovers demand variable end-stops. To match this exact ISO 15552 replacement, verify the 32 mm bore, 600 mm stroke, 50 mm adjustment range, PT G1/8 port, and the -S magnet for CMSE or DMSE sensors. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR.

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 SAIJ32AX600-50S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 Newtons of push force and 345 Newtons of pull force. At a maximum 1.0 MPa pressure, it delivers up to 82 kgf.
The rear adjuster acts as a mechanical stop that allows you to shorten the 600 mm nominal stroke by up to 50 mm, creating a 550-600 mm usable travel window. It only sets the travel end and does not hold the load without live air.
