About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-75S
The AirTAC SAIJ32X100-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. Equipped with a PT tapered G1/8 port and a 12mm carbon steel rod, it delivers 402N of push force at 0.5 MPa. The built-in magnet enables position sensing with CMSE reed and DMSE electronic switches. By dialing back the travel up to 75mm, this model creates a highly flexible 25-100mm usable stroke window without requiring physical cylinder replacement.
This adjustable stopper allows you to fine-tune the retract end-position directly at commissioning or during product changeover. It uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. The extruded aluminum barrel includes sensor grooves on both sides, and the variable air cushions at both ends decelerate the motion, though the adjuster acts only as a travel stop and will not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-75S Is Used
End-Position Tuning
Dial in the exact retract distance within the 25-100mm window during machine commissioning without swapping out the entire cylinder.
Product Changeover
Quickly adapt the stroke length on a packaging line when handling different product sizes, using the rear stopper to set new limits.
Assembly Fixtures
Provide adjustable travel limits for clamping or pressing operations, allowing operators to fine-tune the end position for various part heights.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-75S the Right Cylinder?
Choose this 32mm bore when you need variable end-stops for frequent machine setup or product-size changes, rather than a fixed-stroke SAI cylinder. If your application requires slightly less thrust, stepping down is not an option in this series, but if you need more force, the 40mm bore provides 628N at 0.5 MPa. For load-holding without live pressure, this cylinder will not suffice; consider the SAIL or BSAI series instead. To match this ISO 15552 replacement, specify the 32mm bore, 100mm nominal stroke, 75mm adjustment, PT port thread, and the -S magnet option.
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 SAIJ32X100-75S FAQ
At an operating pressure of 0.5 MPa, this 32mm bore cylinder provides 402N of push force and 345N of pull force. It can deliver up to 724N of push force at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that can shorten the nominal 100mm stroke by up to 75mm, giving you a usable travel window of 25-100mm. It functions as a travel stop and does not lock the load without continuous air pressure.
