About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX270-10S
The AirTAC SAIJ100X270-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 5497N of push force at 0.7 MPa. It features a SUS304 stainless steel rod for corrosion resistance and a PT tapered port thread. The integrated magnet (-S) enables direct position sensing with CMSE reed or DMSE electronic switches.
This model provides a usable travel window of 260-270 mm, allowing you to dial back the nominal 270 mm stroke by up to 10 mm. The rear screw acts purely as a travel stop for end-position tuning during commissioning; it does not lock the load without live air. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX270-10S Is Used
Machine Setup & Commissioning
Fine-tune the 260-270 mm retract end-position during initial machine build without physically swapping cylinders or machining external stopper blocks.
Product Size Changeover
Quickly adjust the stroke by up to 10 mm on packaging lines when running slightly shorter product variants, minimizing downtime between batches.
Sensor-Calibrated Positioning
Leverage the -S magnet with DMSE solid-state sensors to confirm exact end-of-travel after making minor mechanical adjustments to the rear stopper.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX270-10S the Right Cylinder?
Choose this adjustable-stroke cylinder when a standard fixed-stroke SAI cannot accommodate minor mechanical setup variations or product changeovers without adding external stops. The 10 mm adjustment window lets you fine-tune the retract end-position precisely. If your application requires less force, stepping down to an 80 mm bore yields 3518N at 0.7 MPa; if you need more holding power, a 125 mm bore provides 8590N.
For any stroke of 270 mm, the 25 mm rod and M20x1.5 thread handle moderate side loads, but an external guide rail is recommended for heavy off-center loads. Because the adjuster is a stop and not a lock, use a SAIL (pneumatic lock) or BSAI (clamp-lock) cylinder if the load must be held without continuous air pressure. To match this ISO 15552 footprint, specify a 100 mm bore, 270 mm stroke, 10 mm adjustment, PT ports, and the -S magnet.
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 SAIJ100BX270-10S FAQ
At 0.7 MPa operating pressure, this 100 mm bore cylinder provides 5497N of push force and 3681N of pull force. It is rated for a maximum operating pressure of 1.0 MPa.
The rear adjuster screw allows you to shorten the effective stroke from 270 mm down to 260 mm. This creates a 260-270 mm travel window for fine-tuning the end position, but the screw functions only as a mechanical stop and does not hold the load without air pressure.
