About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX150-30
The AirTAC SAIJ100X150-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 3927N push force at 0.5 MPa and uses a PT tapered G1/2 port. The integrated rear stopper allows you to trim the nominal 150mm stroke back by up to 30mm, creating a precise 120-150mm usable travel window for fine-tuning end positions at commissioning.
This model incorporates a SUS304 stainless steel rod for superior corrosion resistance and carries an M20x1.5 rod thread. The extruded aluminum barrel includes sensor grooves on both sides, although this specific SKU is configured without a magnet. The rear adjuster functions strictly as a mechanical stop to set deceleration and end-of-travel limits, meaning it will not hold a load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX150-30 Is Used
Machine Setup & Changeover
Dial in the exact 120 to 150mm end-position during machine commissioning or product size changeovers without physically replacing the cylinder.
Variable End-Stop Positioning
Use the rear adjuster to set precise deceleration points for varying material lengths on a processing line, acting as a repeatable mechanical stop.
Corrosive Assembly Lines
Leverage the SUS304 stainless steel rod and 3927N thrust force for robust actuation in washdown or mildly corrosive industrial assembly environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX150-30 the Right Cylinder?
Choose this 100mm bore when an 80mm bore (providing 2513N push force at 0.5 MPa) is insufficient for your load, but a 125mm bore (6136N) would be excessive overkill. The adjustable 120-150mm travel window is ideal for product changeovers or variable end-stops, eliminating the need to swap out a fixed-stroke SAI cylinder or bolt on external stops. To match this ISO 15552 replacement, specify a 100mm bore, 150mm stroke, 30mm adjustment, PT ports, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and no magnet. For load-holding without continuous air pressure, select a SAIL or BSAI series cylinder instead.
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 SAIJ100BX150-30 FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder generates 3927N of push force and 3681N of pull force. It can deliver up to 7068N of push force at its maximum 0.9 MPa pressure.
The rear adjusting screw acts as a mechanical stop that lets you shorten the effective travel from the 150mm nominal stroke down to a minimum of 120mm. This creates a 120-150mm adjustable window for fine-tuning the retract end position without replacing the cylinder.
