About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX275-100S
The AirTAC SAIJ32X275-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 175-275 mm usable travel window. Delivering 402 N of push force at 0.5 MPa, it provides precise end-position tuning without requiring physical cylinder swaps. The extruded aluminum barrel includes sensor grooves on both sides for straightforward detection mounting.
This variant integrates an SUS420J2 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threads. The 100 mm adjustment range is ideal for accommodating significant product size changes on a line. It supports AirTAC CMSE reed and DMSE solid-state sensors, offering flexible detection options while maintaining a true ISO 15552 mounting interface.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX275-100S Is Used
Variable End-Stop Tuning
Dial in the exact retract distance between 175 and 275 mm during machine commissioning to perfect positioning without adding external physical stops.
Product Size Changeovers
Quickly adapt a packaging line to different package lengths by rotating the rear screw to shift the end position up to 100 mm.
Light-Duty Assembly
Handle precise pressing or clamping tasks using the 402 N output force while relying on the SUS420J2 rod for corrosion resistance.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX275-100S the Right Cylinder?
Choose this 32 mm bore when an application requires 402 N of push force at 0.5 MPa, stepping down from a 40 mm bore that yields 628 N. The 100 mm adjustable stopper is selected over a fixed-stroke SAI when a machine requires extreme travel flexibility for varied product sizes. To replace an ISO 15552 cylinder, match the 32 mm bore, 275 mm nominal stroke, PT port threads, and the -S magnet option. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Because the nominal stroke is 275 mm, an external guide is recommended to prevent excessive side-loading on the 12 mm rod. Remember that the rear adjuster acts strictly as a travel stop and does not hold the load without live air pressure; for true load-holding without air, use an SAIL or BSAI cylinder.
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 SAIJ32AX275-100S FAQ
The rear adjuster acts as an external stopper that trims the effective travel back by up to 100 mm, creating a 175-275 mm usable stroke window. It allows fine-tuning of the end position at commissioning without swapping the cylinder.
At 0.5 MPa, the 32 mm bore provides 402 N of push force and 345 N of pull force. The rear adjuster is a travel stop, not a lock, so it will not hold the load without live air; for load-holding, consider an SAIL or BSAI cylinder.
