About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX650-100
The AirTAC SAIJ32X650-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 100 mm. This creates a usable 550-650 mm adjustment window, letting you fine-tune the retract end position during commissioning without swapping out the barrel or adding bulky external stops. It delivers 402 N of push force at 0.5 MPa and 724 N at 0.9 MPa, making it well-suited for lighter-duty positioning tasks.
This SKU is configured with an SUS420J2 stainless steel rod (material code A) for improved corrosion resistance over standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides, though this specific model is built without a magnet, so it will not trigger position switches. It uses PT tapered port threads (G1/8) and supports a speed range of 30-800 mm/s. The rear adjuster acts purely as a mechanical stop to set the travel limit and does not hold the load if air pressure drops.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX650-100 Is Used
Machine Changeover
Dial in the retract position precisely when switching between product sizes on a packaging line, using the 100 mm travel window to avoid re-machining hard stops.
Assembly Calibration
Fine-tune the end-of-stroke position during initial commissioning to perfect part seating or clamping depth without physically swapping the actuator.
Light Positioning
Move lightweight diverters or gates with 402 N of push force at 0.5 MPa, relying on the rear stopper to set the exact resting distance.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX650-100 the Right Cylinder?
Choose this 32 mm bore when your application requires the 402 N push force at 0.5 MPa rather than stepping up to a 40 mm bore that provides 628 N. The 100 mm adjustment range is particularly useful for product size changeovers on a line, allowing operators to dial in the exact retract position without machining new hard stops. If you need to hold a load in place without live air pressure, a plain SAIJ cannot perform this function; you would need to specify an SAIL pneumatic lock cylinder or an external rod lock instead.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 650 mm stroke, PT G1/8 port, and the 100 mm adjustment code. Mounting options are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because the 650 mm stroke is long relative to the 12 mm rod diameter, it is highly recommended to use an external guide to prevent excessive side-loading and rod deflection during travel.

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 SAIJ32AX650-100 FAQ
It features a rear adjusting screw that acts as a mechanical stop, allowing you to shorten the nominal 650 mm stroke by up to 100 mm. This provides an effective travel window of 550 to 650 mm, which can be fine-tuned during setup without changing the cylinder.
At a 0.5 MPa operating pressure, this 32 mm bore cylinder generates 402 N of push force and 345 N of pull force. At 0.9 MPa, the push force increases to 724 N.
