About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX150-20S
The AirTAC SAIJ100X150-20-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 130 to 150 mm, letting you dial back the end position by up to 20 mm during commissioning without adding external stops. It delivers 3927 N of push force at 0.5 MPa and reaches 7068 N at 0.9 MPa, making it suitable for heavy-duty positioning tasks.
This specific SKU is built with a SUS304 stainless steel rod (code B) for superior corrosion resistance and includes a piston magnet (-S) for position sensing. The integrated sensor grooves on both sides of the extruded aluminum barrel accept AirTAC CMSE reed switches and DMSE solid-state sensors. The rear adjuster acts purely as a travel stop to fine-tune deceleration and end-points; it is not a lock, so the cylinder cannot hold loads without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX150-20S Is Used
Machine Changeover
Quickly fine-tune the retract end-position by up to 20 mm during product size changeovers without swapping actuators or bolting on external stops.
Heavy-Duty Clamping
Leverage 3927 N of push force at 0.5 MPa to secure heavy workpieces, using the SUS304 stainless rod for corrosion resistance in harsh environments.
Variable End Stops
Set precise lower-travel limits within the 130-150 mm window for automated assembly processes that require flexible positioning.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX150-20S the Right Cylinder?
Select this 100 mm bore cylinder when an 80 mm bore (providing 2513 N push at 0.5 MPa) is insufficient for your clamping or lifting force requirements. The adjustable rear stop is ideal for product changeovers on a line where exact end-position tuning is necessary without swapping the entire actuator. Because the 150 mm stroke is under the 300 mm side-load threshold, a separate external guide is not strictly required, though the robust 25 mm rod and M20x1.5 thread handle substantial side loads natively.
To match this ISO 15552 interchangeable cylinder, specify a 100 mm bore, 150 mm stroke, 20 mm adjustment range, PT tapered port threads, and the -S magnet option. If your application requires true load-holding without continuous air pressure, consider the AirTAC SAIL pneumatic lock or BSAI clamp-lock series instead, as the SAIJ adjuster only sets the travel end.
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 SAIJ100BX150-20S FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. If you increase the operating pressure to 0.9 MPa, the push force reaches 7068 N.
The nominal 150 mm stroke can be mechanically dialed back by up to 20 mm via a rear adjusting screw, giving an effective travel window of 130 to 150 mm. This stopper fine-tunes the end position but does not lock the load without live air pressure.
