About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX230-75
The AirTAC SAIJ100X230-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 75 mm. This creates a usable stroke window of 155 to 230 mm, enabling precise end-position tuning at commissioning without swapping out the cylinder or adding external stops. It delivers a robust push force of 3927 N at 0.5 MPa, making it well-suited for heavy-duty positioning tasks.
This specific configuration incorporates a SUS304 stainless steel rod (option B) for superior corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for CMSE or DMSE switches, though this unit is specified without a magnet. The rear adjuster acts purely as a travel stop to work alongside the adjustable air cushions at both ends, meaning it does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX230-75 Is Used
Product Changeover Tuning
Dial in the 155-230 mm travel window during packaging line format changes to accommodate different carton sizes without replacing the actuator.
Heavy-Duty Positioning
Leverage the 3927 N push force at 0.5 MPa to shift heavy jigs or pallets, using the rear stop to fine-tune the final resting position precisely.
Corrosive Assembly Stations
Utilize the SUS304 stainless steel rod in humid or washdown manufacturing environments where carbon steel rods would risk surface degradation.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX230-75 the Right Cylinder?
Choose this 100 mm bore when your application requires pushing 3927 N at 0.5 MPa (or up to 7068 N at 0.9 MPa). If your load demands less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa, whereas a 125 mm bore provides 6133 N for heavier demands. The 75 mm adjustment range is ideal for machinery that undergoes frequent product-size changeovers, allowing the retract end-stop to be dialed in on the fly rather than machining new hard stops.
Because the nominal stroke is 230 mm, the rod end will experience moderate leverage, but the 25 mm rod diameter and M20x1.5 rod thread provide excellent rigidity against side loads. For load-holding without continuous air pressure, note that this cylinder's adjuster is a stop and not a lock; you would need to specify an SAIL (air-released lock) or BSAI (clamp-lock) variant instead. This SAIJ model is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) with PT ports.

- ✓ 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 SAIJ100BX230-75 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. If pressure is increased to 0.9 MPa, the push force reaches 7068 N.
The rear adjuster screw lets you shorten the nominal 230 mm stroke by up to 75 mm, providing an effective travel range of 155 to 230 mm. The adjuster acts as a mechanical stop to set the end position and does not function as a lock to hold the load without air pressure.
