About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX600-20
The AirTAC SAIJ32X600-20 is a double-acting ISO 15552 profile cylinder featuring a 32mm bore and a 600mm stroke, equipped with a rear adjuster that creates a 580-600mm usable travel window. Delivering 402N of push force at 0.5MPa, it uses a PT G1/8 port and an SUS420J2 stainless steel rod (code A) for superior corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to add CMSE reed or DMSE electronic switches later if positioning feedback becomes necessary.
Instead of machining external stop blocks to fine-tune end positions during product changeovers, the integrated rear screw lets you trim up to 20mm of travel directly at commissioning. This adjustable-stroke design uses a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. The variable air cushions at both ends decelerate the load, but remember the adjuster acts only as a travel stop and does not hold the load without live air.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX600-20 Is Used
Product Changeover Tuning
Dial in the exact 580-600mm end-stop during format size changes on a packaging line without machining new external stopper blocks.
Long-Stroke Diverting
Actuate a diverter gate over a 600mm reach, using the rear adjuster to fine-tune the resting position to match varying conveyor widths.
Commissioning Calibration
Trim the final 20mm of travel during machine setup to perfectly seat a lightweight component without over-traveling and damaging the tooling.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX600-20 the Right Cylinder?
Select this 32mm bore model when an application demands precise end-position tuning within a 580-600mm travel window, avoiding the need to physically swap cylinders for minor product size changes. If your setup requires less force, stepping down is not an option below 32mm in this series, but if you need substantially more thrust, a 40mm bore provides 628N at 0.5MPa. Because the 600mm stroke is quite long relative to the 12mm rod diameter, an external guide is strongly recommended to prevent excessive side-loading and premature seal wear.
For a direct ISO 15552 replacement, match the 32mm bore, 600mm stroke, 20mm adjustment, PT G1/8 port, and your desired mounting bracket. This SKU uses an SUS420J2 rod and lacks a magnet. If the machine ever requires load-holding without continuous air pressure, a plain SAIJ will not suffice; you must transition to an external rod lock, a pilot-operated check valve, or AirTAC SAIL and BSAI locking cylinders.

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 SAIJ32AX600-20 FAQ
At 0.5MPa operating pressure, this 32mm bore cylinder generates 402N of push force and 345N of pull force. The standard operating speed range for this bore size is 30-800mm/s.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective retract stroke by up to 20mm. This creates a usable travel window of 580-600mm for fine-tuning end positions without replacing the cylinder.
