About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX175-50
The AirTAC SAIJ100X175-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 125-175 mm usable travel window, allowing you to dial back the 175 mm nominal stroke by up to 50 mm during commissioning. With a 100 mm bore, it delivers 3927 N of push force at 0.5 MPa and 7068 N at 0.9 MPa.
This unit uses a SUS420J2 stainless steel rod for improved corrosion resistance and carries PT tapered G1/2 ports. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX175-50 Is Used
Product Changeover
Dial in the exact retract distance for varying product lengths on a packaging line without changing the cylinder.
Machine Setup
Fine-tune the end-of-stroke position during initial commissioning to perfect timing and avoid mechanical hard stops.
Variable End Stops
Adjust the 125-175 mm travel window on the fly to test different actuation points in a prototype assembly fixture.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX175-50 the Right Cylinder?
Choose this adjustable model over a fixed-stroke SAI when your machine setup requires variable end-stops or product-size changeovers without physically swapping the cylinder or bolting on external stops. If your application needs less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa. For higher force, a 125 mm bore provides 6136 N.
To replace an ISO 15552 cylinder, match the 100 mm bore, 175 mm stroke, 50 mm adjustment, PT G1/2 port, and your required mounting. Remember that the rear adjuster acts only as a travel stop, not a lock; the SAIJ will not hold a load without live air. For load-holding without pressure, consider the SAIL or BSAI series, or use an external pilot-operated check valve. Because the stroke is under 300 mm, side-load concerns are minimal, but the 25 mm rod and M20x1.5 thread handle standard loads effectively.
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 SAIJ100AX175-50 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 shorten the 175 mm nominal stroke by up to 50 mm, creating a 125-175 mm usable travel window. The adjuster acts as a physical stop to fine-tune the retract end position and does not lock the load without live air.
