About the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX600-10S
The AirTAC SAIJ40X600-10-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 590-600 mm usable travel window, allowing you to dial back the 600 mm nominal stroke by up to 10 mm during commissioning. Delivering 879 N of push thrust at 0.7 MPa, it is built with a SUS304 stainless steel rod and a PT tapered port thread for robust pneumatic connections.
This model includes a magnet for position detection, functioning seamlessly with AirTAC CMSE reed and DMSE electronic solid-state sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the mounting options utilize a reduced subset (Basic, FA, LB, TC, FTC, TCM1, TCM2) compared to fixed-stroke variants.

Where the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX600-10S Is Used
Variable End-Stop Tuning
Fine-tune the retract position within a 590-600 mm window during machine commissioning to perfect product placement without mechanical shims.
Product Size Changeover
Quickly adapt automated lines for different part lengths by dialing in the stroke up to 10 mm, minimizing downtime between production runs.
Long-Travel Assembly
Execute extended 600 mm linear movements for component loading or pressing tasks, utilizing the 879 N thrust and integrated sensor feedback.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX600-10S the Right Cylinder?
Choose this 40 mm bore when you need higher force than the 32 mm version (402 N at 0.5 MPa) but less bulk than the 50 mm size (982 N at 0.5 MPa). The adjustable stroke is ideal for machine setups requiring precise end-position tuning without swapping cylinders or adding external stops. For a fixed travel length without the rear adjuster, the standard SAI cylinder is the alternative.
With a 600 mm stroke, the 16 mm rod and M12x1.25 thread carry moderate side loads, but an external guide is recommended for unsupported loads to prevent binding. Note that the rear adjuster and air cushions act only as travel stops and deceleration; they do not hold the load without live air. For true load-holding without pressure, consider the SAIL lock or BSAI clamp-lock cylinders.
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 SAIJ40 Adjustable Cylinder SAIJ40BX600-10S FAQ
At an operating pressure of 0.7 MPa, this 40 mm bore cylinder generates 879 N of push thrust and 739 N of pull thrust. It can deliver up to 1130 N of push force at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective travel from the nominal 600 mm down to 590 mm. This provides a 10 mm fine-tuning window to set the exact end position at commissioning without replacing the cylinder.
