About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX290-10S
The AirTAC SAIJ100X290-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. With a 290mm nominal stroke and a 10mm adjustment range, it provides a 280-290mm usable travel window for fine-tuning end positions during machine commissioning. It delivers 3927N of push force and 3681N of pull force at 0.5 MPa, making it suitable for heavy-duty positioning.
This variant includes a SUS304 stainless steel rod (code B) for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel features sensor grooves on both sides, and because this is an -S model, it includes a magnet compatible with AirTAC CMSE reed and DMSE solid-state sensors. The rear adjuster acts purely as a travel stop to set deceleration, not as a lock to hold loads without live air.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX290-10S Is Used
Machine Changeover
Dial in the 280-290mm travel window during product size changes to set exact end-stops without replacing the cylinder or adding shims.
Heavy Positioning
Leverage 3927N of push force at 0.5 MPa to move heavy pallets or fixtures, using the rear stop to fine-tune the final rest position.
Washdown Handling
Utilize the SUS304 stainless steel rod and DMSE solid-state sensors for reliable actuation in corrosive or frequently washed environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX290-10S the Right Cylinder?
Choose this 100mm bore when 50mm (982N push at 0.5 MPa) is too weak but 125mm (6136N) is oversized. The adjustable 280-290mm window is ideal for product changeovers where exact end-position tuning is required without swapping cylinders. For holding loads safely without live air pressure, select SAIL or BSAI instead, as the SAIJ adjuster is not a brake. To replace an ISO 15552 cylinder, match the 100mm bore, 290mm stroke, PT ports, SUS304 rod, and -S magnet.
Since the 290mm stroke is substantial, the 25mm rod diameter and M20x1.5 rod thread provide rigidity, but an external guide is still recommended to prevent side-loading damage on long unsupported travels. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

- ✓ 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 SAIJ100BX290-10S FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 10mm, providing a 280-290mm travel window. It acts as a mechanical stop to tune the end position and works with the air cushion for deceleration, but it does not lock the load without live air pressure.
At 0.5 MPa it provides 3927N of push force and 3681N of pull force. At 0.7 MPa the push force increases to 5497N, with a maximum operating pressure of 1.0 MPa.
