About the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX290-10
The AirTAC SAIJ50X290-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel. With a 290 mm nominal stroke and a 10 mm adjustment range, it provides a 280-290 mm usable travel window for precise end-position tuning during commissioning. It delivers 982 N of push force at 0.5 MPa and 1767 N at 0.9 MPa.
This model features a SUS420J2 stainless steel rod (code A) for improved corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and while this specific SKU lacks a magnet, adding an -S magnet enables compatibility with AirTAC CMSE reed and DMSE solid-state sensors. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX290-10 Is Used
Variable End-Stop Machining
Dial in the exact 280-290 mm clamping distance during machine setup to accommodate different part lengths without external stopper hardware.
Product Changeover Lines
Quickly adjust the retract end-position on packaging conveyors when switching between product sizes, minimizing line downtime.
Commissioning Fine-Tuning
Trim the stroke by up to 10 mm during initial commissioning to perfectly sync cylinder travel with machine timing and avoid hard mechanical crashes.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX290-10 the Right Cylinder?
Choose this 50 mm bore model when your application requires 982 N of push force at 0.5 MPa, stepping up from a 40 mm bore that provides 628 N, or down from a 63 mm bore yielding 1559 N. An adjustable stroke is ideal for machine setups requiring variable end stops or product-size changeovers without swapping the entire cylinder or adding external stops. For load-holding without live air pressure, consider the SAIL or BSAI series, as the SAIJ adjuster is not a locking mechanism.
At a 290 mm stroke, the 20 mm piston rod and M16x1.5 rod thread provide robust side-load capacity, but an external guide is still recommended for unsupported loads. This cylinder is dimensionally interchangeable per ISO 15552 and supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2. It operates at speeds of 30-800 mm/s and uses a G1/4 port.

- ✓ 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 SAIJ50 Adjustable Cylinder SAIJ50AX290-10 FAQ
At 0.5 MPa it provides 982 N of push force and 825 N of pull force. At 0.9 MPa, the push force increases to 1767 N.
The rear adjuster screw lets you shorten the 290 mm nominal stroke by up to 10 mm, creating a 280-290 mm travel window for fine-tuning the end position without replacing the cylinder.
