About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX95-40
The AirTAC SAIJ100X95-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 95 mm stroke that can be dialed back by up to 40 mm, creating a precise 55-95 mm usable travel window for product changeovers. Delivering 3927 N of push force at 0.5 MPa, it handles heavy positioning tasks without requiring cylinder swaps.
This variant uses a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to add CMSE reed or DMSE electronic switches if needed. The rear screw acts purely as a travel stop to fine-tune deceleration, not as a lock to hold loads without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX95-40 Is Used
Variable End-Stop Tuning
Dial in the exact 55 to 95 mm stroke distance during machine setup to accommodate different material thicknesses without adding external stopper blocks.
Heavy Press Positioning
Leverage the 3927 N push force at 0.5 MPa to move heavy jigs into place, using the rear adjuster to fine-tune the final contact position.
Product Size Changeover
Quickly reconfigure production lines for new part dimensions by turning the rear screw, reducing downtime between short production runs.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX95-40 the Right Cylinder?
Choose this 100 mm bore when a smaller 80 mm cylinder (providing 2513 N push at 0.5 MPa) lacks the thrust for your tooling, but a 125 mm unit is physically too large. The 40 mm adjustment range is ideal for machines processing multiple product sizes, letting operators set exact end positions at commissioning rather than machining external stops. Because the nominal stroke is under 300 mm, side-load risks are manageable, though the robust 25 mm rod and M20x1.5 thread help withstand moderate offset stresses. For applications requiring the cylinder to hold a load without continuous air pressure, select a SAIL or BSAI model instead, as the SAIJ adjuster is not a locking device. To match this ISO 15552 footprint, specify the 100 mm bore, 95 mm stroke, PT ports, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, 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 SAIJ100BX95-40 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw allows you to shorten the effective travel from the nominal 95 mm down to 55 mm. It functions as a mechanical stop to set the end position, but it does not lock the load without live air pressure.
