About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX260-100S
The AirTAC SAIJ100X260-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 160-260 mm usable travel window, letting you dial back the nominal 260 mm stroke by up to 100 mm during commissioning without adding external stops. It delivers a robust 3927 N push force at 0.5 MPa, making it suitable for heavy positioning tasks.
This variant integrates a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet supports CMSE reed and DMSE electronic switches for precise end-of-stroke detection.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX260-100S Is Used
Variable End-Stop Positioning
Dial in the exact retract distance between 160 and 260 mm on machining fixtures to accommodate different part lengths without swapping out the cylinder.
Production Line Changeover
Rapidly reconfigure assembly stations for new product variants by turning the rear adjuster screw, saving setup time compared to replacing fixed-stroke SAI cylinders.
Diverter Gate Adjustment
Fine-tune the actuation distance of heavy conveyor sorting gates on the fly, ensuring precise package handling across varying box sizes.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX260-100S the Right Cylinder?
Choose this 100 mm bore when a 80 mm bore (providing 2513 N push at 0.5 MPa) lacks the force for heavier payloads, but a 125 mm bore is excessive. The 100 mm adjuster is ideal for product changeovers requiring vastly different end positions. For load-holding without live air pressure, select a SAIL or BSAI lock cylinder instead, as the SAIJ adjuster is a travel stop, not a brake.
Because the 260 mm stroke exceeds 300 mm? No, but for long strokes approaching this length, supporting the load with an external guide prevents rod bending. This model is dimensionally interchangeable per ISO 15552. Match the exact replacement by specifying the 100 mm bore, 260 mm stroke, 100 mm adjustment, PT ports, Basic/LB/TC mounting, 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 SAIJ100BX260-100S 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 0.9 MPa, the push force reaches 7068 N.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke from 260 mm down to as little as 160 mm. This creates a 100 mm adjustable travel window for fine-tuning end positions at commissioning, but it does not lock the load without live air pressure.
