About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX300-100S
The AirTAC SAIJ32X300-100-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 200 to 300 mm, allowing you to dial back the nominal 300 mm stroke by up to 100 mm during commissioning. This bore size delivers 402 N of push force at 0.5 MPa and utilizes a PT G1/8 port.
Built with a SUS304 stainless steel rod (option B), this unit handles demanding environments while resisting corrosion. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed and DMSE electronic switches. The rear adjuster acts purely as a mechanical stop to fine-tune the end position without adding external stops.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX300-100S Is Used
Product Changeover Tuning
Quickly adjust the retract end-position by up to 100 mm when switching between packaging formats or product lengths on a single line.
Variable End Stops
Set precise push-off distances for varying package widths without physically swapping the cylinder or adding bulky external stopper blocks.
Machine Commissioning Setup
Fine-tune the final resting position during initial machine build to perfectly align tooling, avoiding the need to machine custom spacer rings.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX300-100S the Right Cylinder?
Select this 32 mm bore cylinder when your application requires precise end-position tuning on the fly, such as accommodating varying product sizes on a conveyor. If your setup needs higher thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. Because the 300 mm stroke is relatively long for this smaller 12 mm rod diameter, external guidance is recommended to prevent excessive side-loading and premature seal wear.
This SAIJ model uses a reduced mounting interface set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. The rear adjuster and built-in air cushions only decelerate the load; they do not hold position without live air pressure. For true load-holding, consider the SAIL or BSAI series instead.
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 SAIJ32BX300-100S FAQ
The rear adjuster screw lets you shorten the effective travel from the nominal 300 mm down to 200 mm. This creates a 200-300 mm adjustable window, allowing you to set the exact retract end-position during commissioning without replacing the cylinder.
At a standard 0.5 MPa operating pressure, it provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it can generate up to 801 kgf of push force.
