About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX195-100
The AirTAC SAIJ100X195-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers 3927N of push force at 0.5MPa and provides a usable travel window of 95 to 195mm, letting you dial in the exact end position without swapping hardware. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches.
This specific SKU utilizes a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads (G1/2). The generous 100mm adjustment range is ideal for product changeovers, acting purely as a mechanical stop to set the travel end. It does not hold the load without live air pressure, so use a SAIL or BSAI lock cylinder if fail-safe holding is required.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX195-100 Is Used
Product Changeover
Quickly adjust the 95-195mm travel window during packaging format changes without replacing the cylinder.
End-Position Tuning
Fine-tune the retract stroke at machine commissioning to hit exact datum points safely.
Variable End Stops
Set multiple retract positions on an assembly line for different part heights using the 100mm stopper.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX195-100 the Right Cylinder?
Select this 100mm bore when you need robust thrust up to 3927N at 0.5MPa, stepping up from a 63mm bore that provides 1559N. The 100mm adjustment window is perfect for commissioning fine-tunes or variable end-stops on product-size lines, saving the downtime of changing a fixed SAI cylinder. For ISO 15552 replacement matching, verify the 195mm stroke, 100mm adjustment, G1/2 PT port, and your required mounting from the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, TCM2.
Because the 195mm stroke approaches the mid-range of unsupported travel, the M20x1.5 rod thread and 25mm rod diameter handle moderate side loads, but an external guide is still recommended for heavy off-center loads. Note that the rear adjuster only sets the travel end; it is not a brake.
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 SAIJ100BX195-100 FAQ
This 100mm bore cylinder provides 3927N of push thrust and 3681N of pull thrust at 0.5MPa. At 0.7MPa, the push force increases to 5497N.
The rear adjuster acts as a mechanical stop, allowing you to shorten the effective travel from 195mm down to 95mm. It only sets the end position and does not lock the load without live air.
