About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX600-40
The AirTAC SAIJ32X600-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 560-600mm usable travel window. Delivering 402N of push force at 0.5 MPa, it allows operators to dial in the exact retract position without adding external stops. This 32mm bore unit uses a PT tapered port and a SUS304 stainless steel rod for superior corrosion resistance.
Because the adjuster functions strictly as a mechanical stop and not a lock, it cannot hold a load without live air pressure. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE or DMSE switches if a magnet is added later. It supports a speed range of 30-800 mm/s and uses adjustable air cushions at both ends to manage deceleration.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX600-40 Is Used
Machine Changeover
Dial in the 560-600mm retract position during product size changes without swapping out the entire cylinder or repositioning hard stops.
End-Position Tuning
Fine-tune the final retract point at commissioning to absorb mechanical tolerances in long-stroke assemblies.
Variable End Stops
Adjust the stroke on the fly for sorting or diverter mechanisms that require slightly different travel distances per SKU.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX600-40 the Right Cylinder?
Choose this 32mm bore when you need precise retract fine-tuning during machine commissioning or product changeovers, stepping up from smaller units if you need slightly more force than a compact cylinder offers. If your application requires higher thrust, a 40mm bore provides 628N at 0.5 MPa. For load-holding without continuous air pressure, consider the SAIL or BSAI series instead of relying on the SAIJ adjuster.
At 600mm of stroke, the 12mm rod is susceptible to side-loading; an external guide rail is recommended to prevent binding. To match this ISO 15552 interchangeable cylinder exactly, specify: 32mm bore, 600mm stroke, 40mm adjustment, PT ports, SUS304 rod, and no magnet. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ32BX600-40 FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke by up to 40mm, creating a 560-600mm travel window. It only sets the end position and does not lock the load without live air pressure.
At 0.5 MPa operating pressure, it provides 402N of push force and 345N of pull force. At 0.7 MPa, the push force increases to 563N.
