About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-100
The AirTAC SAIJ100X190-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 90 to 190 mm. Fitted with a SUS304 stainless steel rod and PT tapered ports, it delivers a robust 3927 N push force at 0.5 MPa. This bore size features a 25 mm rod and M20x1.5 thread, giving it excellent rigidity to handle higher side loads during extension.
Instead of relying on fixed stops, the rear adjusting screw lets you dial in the exact retract position during commissioning or product changeover. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for pneumatic locking, consider the SAIL or BSAI series.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-100 Is Used
Product Size Changeovers
Quickly trim the retract distance up to 100 mm when running a new packaging size on the line, eliminating the need to physically swap out cylinders or reposition external hard stops.
End-Position Tuning
Fine-tune the final resting position of the tooling during machine commissioning to achieve perfect alignment, absorbing mechanical tolerances without adding spacer blocks.
Heavy Forming Operations
Leverage the 3927 N push force at 0.5 MPa for pressing or forming tasks, using the adjustable stroke to precisely control the engagement depth of the tool.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-100 the Right Cylinder?
Choose this 100 mm bore when an 80 mm bore (2513 N push at 0.5 MPa) cannot provide enough thrust, but you want to avoid stepping up to a 125 mm cylinder (6136 N). The generous 100 mm adjustment range is ideal for machines processing varying product sizes, allowing you to reposition the end-stop on the fly without swapping the cylinder. Although the 190 mm stroke is under the 300 mm side-load threshold, the heavy 25 mm rod still provides strong resistance to deflection.
When matching an ISO 15552 replacement, verify the 190 mm stroke, 100 mm adjustment code, PT port threads, and your required mounting style. SAIJ supports a specific subset of mounts: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because this configuration lacks a magnet (-S), it cannot host CMSE reed or DMSE electronic sensors without a model change.

- ✓ 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 SAIJ100BX190-100 FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. If you increase the pressure to 0.7 MPa, the push force rises to 5497 N.
The rear adjuster screw allows you to shorten the 190 mm nominal stroke by up to 100 mm, creating a usable travel window of 90 to 190 mm. It functions purely as a mechanical stop to set the end position and does not lock the load pneumatically.
