About the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX95-30
The AirTAC SAIJ40X95-30 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 95 mm stroke that can be fine-tuned down by up to 30 mm, giving operators a usable travel window of 65 to 95 mm.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads with a G1/4 connection. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to add CMSE reed or DMSE electronic switches later if positioning feedback becomes necessary.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 528 N | 528 N |
| 0.7 MPa | 739 N | — |
| Max (@1.0 MPa) | 108 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX95-30 Is Used
Product Changeovers
Dial in the 65 to 95 mm travel window during format changes on packaging lines, avoiding the need to swap out physical hard stops.
End-Position Tuning
Fine-tune the retract distance at machine commissioning to perfect the picking or pressing depth without mechanical rework.
Corrosive Assembly Tasks
Leverage the SUS304 stainless steel rod for light pushing and clamping duties in environments where standard carbon steel rods would degrade.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX95-30 the Right Cylinder?
The 30 mm adjustment range is ideal for product changeovers, letting you dial in the exact end position without adding external stops or replacing the cylinder. If your process requires the load to stay held without continuous air pressure, note that this adjuster acts only as a travel stop; you would need an external pilot-operated check valve or a related SAIL lock cylinder.
For an exact ISO 15552 replacement, match the 40 mm bore, 95 mm stroke, 30 mm adjustment, PT port, and your required mounting bracket from the available Basic, FA, LB, TC, FTC, TCM1, or TCM2 sets. Because the stroke is under 300 mm, side-load stress is minimal, but the robust 16 mm rod still handles standard operational loads effectively.
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 SAIJ40 Adjustable Cylinder SAIJ40BX95-30 FAQ
The rear adjuster screw acts as a mechanical stop that shortens the retract stroke. For this 95 mm nominal stroke cylinder, you can trim the effective travel back by up to 30 mm, creating a precise 65 to 95 mm operating window without replacing the cylinder.
