About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX175-100S
The AirTAC SAIJ100X175-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 75 to 175 mm. It delivers substantial thrust, generating 5497N of push force at 0.7 MPa, making it suitable for heavy-duty positioning tasks.
This variant features a SUS420J2 stainless steel rod for enhanced corrosion resistance and includes a magnet for CMSE and DMSE sensors. The rear adjuster acts as a travel stop for fine-tuning end positions during commissioning; it does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX175-100S Is Used
Variable End-Stop Positioning
Dial in the exact retract distance from 75 to 175 mm during machine setup to accommodate different product sizes without changing hardware.
Heavy-Duty Clamping
Leverage 5497N of push force at 0.7 MPa to secure heavy workpieces, using the rear stop to precisely tune the clamp position.
Product Changeover Systems
Quickly adjust the cylinder's effective stroke on automated lines to handle varying material widths or formats on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX175-100S the Right Cylinder?
Choose this 100mm bore cylinder when a 63mm bore (2182N push at 0.7 MPa) lacks sufficient force for your variable end-stop application. The 100mm adjustment range allows significant product changeover flexibility without swapping cylinders. For load-holding without live air, consider an AirTAC SAIL or BSAI cylinder instead, as the adjuster here is strictly a stop, not a lock.
This model uses PT tapered ports and a SUS420J2 rod. It supports the SAIJ mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. If you need a fixed end position, the standard SAI cylinder is a simpler alternative. For any stroke over 300mm, use an external guide to prevent side-load wear.
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 SAIJ100AX175-100S FAQ
The rear adjuster allows you to shorten the effective travel by up to 100 mm, creating a usable stroke window of 75 to 175 mm. It acts as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
At 0.7 MPa operating pressure, the SAIJ100X175-100-S generates 5497N of push force and 5148N of pull force. It can reach a maximum push force of 7068N at 0.9 MPa.
