About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX195-40
The AirTAC SAIJ100X195-40 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 5497N push force at 0.7MPa, making it suitable for heavy-duty positioning tasks. The integrated PT tapered ports and SUS304 stainless steel rod provide excellent durability and corrosion resistance in demanding environments.
This model features a 195mm nominal stroke that can be fine-tuned down by up to 40mm, creating a precise 155-195mm usable travel window. An extruded aluminum barrel incorporates sensor grooves on both sides, allowing for flexible mounting of CMSE or DMSE switches if a magnet is added later. The adjustable rear stopper sets the retract end position, while the variable air cushions handle deceleration.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX195-40 Is Used
Machine Setup Tuning
Dial in the exact 155-195mm end position during initial commissioning to perfect a pressing or clamping operation without machining custom spacers.
Product Changeover
Quickly adjust the retract stop to accommodate different product lengths on a packaging line, reducing downtime between production runs.
Variable End Stops
Use the 40mm adjustment range to fine-tune the deceleration point in conjunction with the standard air cushions for sensitive load placement.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX195-40 the Right Cylinder?
Choose this 100mm bore when a 63mm cylinder (2182N push at 0.7MPa) lacks the thrust for your process, but a 125mm unit is physically excessive. An adjustable-stroke cylinder is preferred over a fixed SAI model when you need to dial in the exact end-of-travel position during commissioning or product changeover without adding external stops. The 25mm rod and M20x1.5 thread handle significant side loads, but because the stroke approaches 200mm, ensure adequate external guiding for the load.
This SKU omits the FB, CA, CB, and CR mounting styles, utilizing a reduced ISO 15552 set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. The rear adjuster is a mechanical stop, not a lock; it cannot hold a load without live air pressure. For fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder, or an external pilot-operated check valve.
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 SAIJ100BX195-40 FAQ
At 0.7MPa operating pressure, this 100mm bore cylinder provides 5497N of push force and 5184N of pull force. It can achieve a maximum push force of 7068N at 0.9MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from the 195mm nominal down to 155mm. It sets the travel end and works with the air cushions for deceleration, but it does not lock the load without continuous air pressure.
