About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX165-100S
The AirTAC SAIJ32X165-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 165 mm travel back by up to 100 mm, creating a wide 65-165 mm usable window for high-flexibility machine setups. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa, utilizing a 12 mm carbon steel core rod threaded M10x1.25. This specific configuration includes a SUS304 stainless steel rod (code B) for superior corrosion resistance and a built-in magnet (-S) for use with CMSE reed and DMSE electronic sensors.
Unlike a fixed-stroke SAI cylinder, this model lets you fine-tune the retract end-position at commissioning without swapping hardware or adding external stops. The rear adjuster acts purely as a travel stop and works alongside the 27 mm variable air cushions at both ends to decelerate the load. Mounting options cover the reduced SAIJ set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX165-100S Is Used
Variable End-Position Setup
Dial in the exact retract distance between 65 and 165 mm during machine commissioning to perfectly align tooling without machining custom spacers.
Product Size Changeover
Rapidly adapt a packaging line for different carton lengths by adjusting the rear stopper screw to meet new format requirements on the fly.
Corrosive Environment Testing
Leverage the SUS304 stainless steel rod and optional Viton H seals for precise stroke adjustments in laboratory or washdown testing rigs.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX165-100S the Right Cylinder?
Select this 32 mm bore cylinder when your application requires variable end-stops or frequent product-size changeovers, stepping up from smaller actuators while staying within a compact 402 N thrust class at 0.5 MPa. If your setup demands higher force, stepping up to the 40 mm bore yields 628 N of push force. When specifying a replacement, ensure you match the 32 mm bore, 165 mm stroke, 100 mm adjustment range, PT tapered port threads, and the -S magnet requirement.
Because the stroke is 165 mm, the 12 mm rod and M10x1.25 thread provide reasonable side-load capacity, but an external guide rail is still recommended for heavy lateral loads. Remember that a plain SAIJ does not hold its position or load without live air—the rear adjuster is a travel stop, not a lock. For true load-holding without continuous air pressure, consider the SAIL pneumatic lock or BSAI clamp-lock series.
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 SAIJ32BX165-100S FAQ
The rear adjusting screw acts as a mechanical stopper that lets you shorten the effective stroke by up to 100 mm. This creates a usable travel window of 65 to 165 mm, allowing fine-tuning of the end position at commissioning without replacing the cylinder.
At 0.5 MPa it provides 402 N of push force and 345 N of pull force. Operating speed ranges from 30 to 800 mm/s, and it uses G1/8 ports.
