About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX150-10
The AirTAC SAIJ100X150-10 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 150 mm stroke that can be fine-tuned down by up to 10 mm, creating a precise 140-150 mm usable travel window. In the 100 mm bore class, it delivers 3927 N of push force and 3681 N of pull force at 0.5 MPa, making it suitable for heavy-duty positioning tasks.
This variant features a SUS304 stainless steel rod (code B) for superior corrosion resistance and uses PT tapered port threads with a G1/2 connection. The extruded aluminum barrel includes sensor grooves on both sides. While it lacks a standard magnet, the rear stopper allows exact end-position calibration at commissioning without adding external stops, acting solely as a travel limit rather than a load-holding lock.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX150-10 Is Used
Precision End-Stop Tuning
Dial in the exact 140-150 mm travel distance during machine commissioning to perfect the final positioning of heavy jigs without mechanical shims.
Product Changeover
Quickly adjust the rear stopper by up to 10 mm to accommodate slightly different product sizes on a packaging line, minimizing downtime.
Heavy-Duty Positioning
Leverage the 3927 N push force at 0.5 MPa to move and stop substantial loads, relying on the 25 mm rod for robust structural support.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX150-10 the Right Cylinder?
Select this 100 mm bore cylinder when an application requires substantial thrust—up to 5497 N push at 0.7 MPa—combined with exact end-position tuning. If the 10 mm adjustment range is insufficient for your setup, stepping down to an 80 mm bore yields 2513 N push at 0.5 MPa but retains the same rear-tuning mechanics. The adjustable stroke is ideal for product changeovers, letting you dial in the 140-150 mm travel window on the fly instead of physically swapping cylinders.
Because the stroke is 150 mm, side-load stress is moderate, but the 25 mm rod diameter handles standard loads well; for longer unsupported strokes, always use an external guide. Remember that the rear adjuster and air cushion only decelerate the stroke end; they do not hold the load without live air. For true load-holding without pneumatic pressure, consider an AirTAC SAIL or BSAI variant. This model is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

- ✓ 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 SAIJ100BX150-10 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster acts as an external stopper that lets you shorten the effective stroke from its 150 mm nominal length down to 140 mm. This allows fine-tuning of the end position during setup without needing to replace the cylinder.
