The AirTAC SAIJ100 Adjustable Cylinder SAIJ100BX30-10S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 30mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
It features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing. The integrated rear stopper allows you to fine-tune the end position at commissioning without adding external stops.
With a 30 mm nominal stroke and a 10 mm adjustment range, this SKU provides a usable travel window of 20 to 30 mm. It uses PT tapered ports and supports adjustable air cushions at both ends. The extruded aluminum barrel includes sensor grooves on both sides, directly compatible with AirTAC CMSE reed and DMSE electronic solid-state switches.

Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Dial in the exact end-stop from 20 to 30 mm during format changes on a packaging line, eliminating the need to physically swap cylinders for different package sizes.
Fine-tune the clamping end-position at commissioning to prevent over-travel, using the rear screw to perfectly set the stroke without external mechanical stops.
Choose this 100 mm bore cylinder when an application demands high thrust (5497N at 0.7 MPa) but only short, finely tuned travel. If your force requirements are lower, stepping down to an 80 mm bore yields 3518N at 0.7 MPa, whereas moving up to 125 mm provides 8590N. The adjustable stroke is ideal for machine setups requiring a variable end-stop during product changeovers, offering flexibility that a fixed-stroke SAI cylinder cannot match.
For load-holding applications, remember that the rear adjuster functions strictly as a travel stop, not a lock; this SAIJ cylinder will not hold its load without live air pressure. For dead-end holding, consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder. The mounting interface uses the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Quick checklist
The rear adjuster acts as an external stopper that lets you shorten the effective stroke by up to 10 mm. For this 30 mm stroke model, it provides a usable travel window of 20 to 30 mm, which is set during commissioning without swapping the cylinder.
