About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX175-75
The AirTAC SAIJ100X175-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits a usable travel window of 100 to 175 mm. It delivers substantial thrust, generating 3927 N of push force at 0.5 MPa and reaching 7068 N at 0.9 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible positioning of CMSE reed or DMSE electronic switches.
This variant integrates a SUS420J2 stainless steel rod for enhanced corrosion resistance and utilizes PT tapered ports. The rear adjustment screw acts purely as a travel stop to decelerate the end-of-stroke position, meaning it does not hold the load without live air pressure. For true load-holding requirements, an external rod lock or the AirTAC SAIL pneumatic lock cylinder is required.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX175-75 Is Used
Machine Changeover
Dial in the exact 100-175 mm end-stop during product size transitions without physically swapping out the cylinder.
Press Fit Tuning
Fine-tune the rear stroke on a 7068 N assembly press to compensate for material thickness variations at commissioning.
Variable End Stops
Set precise retraction depths on a clamping fixture where the effective travel must be adjusted per batch.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX175-75 the Right Cylinder?
Select this 100 mm bore model when an application demands high force combined with exact end-position tuning during commissioning. If the 100 mm bore's 3927 N push force at 0.5 MPa is excessive for your payload, stepping down to an 80 mm bore yields 2513 N. Conversely, if you need greater thrust, the 125 mm bore provides 6136 N. The integrated adjuster allows you to dial in the exact 100-175 mm stroke without adding external stops or replacing the cylinder.
When replacing an ISO 15552 cylinder, verify the 100 mm bore, 175 mm nominal stroke, 75 mm adjustment range, G1/2 port size, and PT thread type. This SAIJ configuration uses a SUS420J2 rod and omits a magnet, so position sensing is not available out of the box. The mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ100 Adjustable Cylinder SAIJ100AX175-75 FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw lets you trim the effective travel back by up to 75 mm from the 175 mm nominal stroke, creating a 100-175 mm usable window. The screw acts as a mechanical stop and does not lock the load without live air.
