About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX300-10
The AirTAC SAIJ100X300-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position. It provides a usable travel window of 290-300 mm, letting you dial back the nominal 300 mm stroke by up to 10 mm without adding external stops.
This unit is built with a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. It operates at speeds between 30-800 mm/s and includes variable air cushions at both ends to decelerate the load. The extruded aluminum barrel integrates sensor grooves on both sides, allowing you to add CMSE reed or DMSE electronic sensors later if position feedback becomes necessary.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 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 SAIJ100 Adjustable Cylinder SAIJ100BX300-10 Is Used
Precision End-Stop Tuning
Perfect for dialing in exact retract positions during machine commissioning, allowing 10 mm of rear adjustment to perfect the 300 mm stroke without hardware changes.
Product Size Changeover
Ideal for packaging lines that run multiple product lengths, enabling operators to quickly adjust the end-stop window from 290 to 300 mm for varying formats.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX300-10 the Right Cylinder?
The adjustable rear stop is highly beneficial for machine setup and product changeover, allowing you to trim the end position by 10 mm on the fly rather than swapping a fixed-stroke SAI cylinder. To match this exact configuration for an ISO 15552 replacement, specify bore 100, stroke 300, 10 mm adjustment, PT port thread, SUS304 (B) rod material, and no magnet.
Because the stroke is 300 mm, the unsupported load is susceptible to side-loading forces; an external guide rail should be used to prevent rod binding. Furthermore, the rear adjuster acts solely as a travel stop to set deceleration points, not as a locking mechanism. If your application requires the load to be held without live air pressure, you must use an external rod lock, a pilot-operated check valve, or transition to the SAIL or BSAI cylinder series. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and 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 SAIJ100BX300-10 FAQ
At 0.7 MPa, the push force increases to 5497 N.
The rear adjusting screw acts as a mechanical stop that shortens the effective stroke. For this 300 mm stroke model, it creates a usable travel window of 290-300 mm, allowing you to fine-tune the retract position without swapping the cylinder.
