About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX200-75S
The AirTAC SAIJ32X200-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 125-200mm usable travel window. Delivering 402N of push force at 0.5 MPa, it utilizes a 12mm SUS420J2 stainless steel rod and PT tapered ports for reliable performance in compact setups.
Equipped with a magnet (-S), it supports CMSE reed and DMSE electronic sensors housed within the dual-side extruded aluminum barrel grooves. The rear stopper allows precise end-position tuning during commissioning without adding external stops, while the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) omits FB, CA, CB, and CR options.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX200-75S Is Used
Product Changeovers
Dial in the exact end position for varying part sizes on a packaging line using the 75mm rear adjustment window, avoiding physical cylinder swaps.
Machine Commissioning
Fine-tune the retract stroke during initial setup to perfectly time machine sequences without fabricating external mechanical stops.
Variable End Stops
Provide adjustable positioning for light-duty pick-and-place tasks, utilizing the 402N thrust and CMSE/DMSE sensor feedback.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX200-75S the Right Cylinder?
Choose this 32mm bore when an application requires fine-tuning of the retract end within a 125-200mm range, stepping up from a smaller unit or down from a 40mm bore that yields 628N push force at 0.5 MPa. The generous 75mm adjustment window is ideal for product changeovers, allowing operators to dial in the exact stroke without swapping the cylinder.
For this 200mm stroke, the 12mm rod handles moderate side loads, but an external guide is recommended for heavy off-center loads. Because the rear adjuster acts only as a travel stop and the air cushion provides deceleration, neither will hold a load without live air; for true load-holding, consider an external rod lock or the SAIL lock variant. This dimensionally interchangeable ISO 15552 cylinder uses PT ports and a -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 SAIJ32AX200-75S FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At 0.7 MPa, the push force increases to 563N.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective travel from the nominal 200mm down to 125mm. It sets the end position but does not lock the load without live air pressure.
