About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX260-10
The AirTAC SAIJ100X260-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. With a nominal stroke of 260 mm and a 10 mm adjustment range, it provides a usable travel window of 250 to 260 mm. This allows you to dial in the exact retract position at commissioning without swapping hardware. It delivers 3927 N of push force at 0.5 MPa and 7068 N at 0.9 MPa.
This variant features a SUS304 stainless steel piston rod (option B) for superior corrosion resistance. It uses PT tapered G1/2 ports and offers variable air cushions at both ends. The extruded aluminum barrel includes dual sensor grooves, though this specific SKU is configured without a magnet. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX260-10 Is Used
Machine Setup & Changeover
Fine-tune the 250-260 mm retract end-stop during machine commissioning or product size changes without physically swapping the cylinder.
Variable End Stops
Dial in the exact clamping or positioning depth on the fly using the rear adjuster, accommodating material thickness variations.
Corrosive Assembly Lines
Leverage the SUS304 stainless steel rod for reliable actuation in wash-down or mildly corrosive manufacturing environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX260-10 the Right Cylinder?
Choose this 100 mm bore when a 80 mm bore (2268 N pull at 0.5 MPa) is insufficient for your load. The 10 mm adjustable window is ideal for product changeovers on a line, letting you shift the end position by up to 10 mm rather than installing a fixed-stroke SAI cylinder or external stops. For holding loads without live air, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster is not a lock.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 260 mm stroke, PT G1/2 port, and mounting style. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts. Because the 260 mm stroke is substantial, ensure external guidance is used to prevent side-loading on the SUS304 rod.
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 SAIJ100BX260-10 FAQ
At 0.5 MPa, it provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster acts as a mechanical stop, allowing you to shorten the 260 mm nominal stroke by up to 10 mm, creating a 250-260 mm usable travel window. It does not lock the load without live air pressure.
