The AirTAC SAIJ80 Adjustable Cylinder SAIJ80BX170-30S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 170mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAIJ80X170-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the nominal 170 mm travel back by up to 30 mm, yielding a usable 140-170 mm end-position window. The extruded aluminum barrel integrates sensor grooves on both sides for direct CMSE reed or DMSE electronic switch mounting.
This adjustable variant omits the FB, CA, CB, and CR mounts, retaining a focused SAIJ accessory set of Basic, FA, LB, TC, FTC, TCM1, and TCM2. The PT tapered ports and M20x1.5 rod thread provide robust mechanical connections, while the 36 mm air cushions at both ends manage end-of-stroke deceleration across its 30-800 mm/s speed range.

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 140-170 mm retract position during machine commissioning without adding external physical stops or changing the cylinder.
Quickly adapt the retract depth on a packaging line when product sizes change, using the rear screw to trim up to 30 mm of stroke.
Leverage the SUS304 stainless steel rod for corrosion resistance in light-duty assembly stations requiring precise end-position tuning.
The adjustable stroke is selected for machine setups requiring a variable end-stop to fine-tune the retract position during commissioning or product changeover, avoiding the need to swap out a fixed-stroke SAI cylinder.
For any stroke at or above 300 mm, an external guide is recommended to manage side loads, though this 170 mm travel is well within standard limits. Remember that the rear adjuster functions strictly as a travel stop and the air cushions only manage deceleration; neither will hold a load without live air pressure. For true load-holding, utilize the SAIL air-released lock or BSAI clamp-lock variants. This configuration is dimensionally interchangeable per ISO 15552, uses PT ports, includes the -S magnet, and supports the specified mounting set.
Quick checklist
It operates at a speed range of 30-800 mm/s and features a 25 mm rod with an M20x1.5 thread.
The rear adjuster acts as a mechanical stop that allows you to shorten the 170 mm nominal stroke by up to 30 mm, creating a 140-170 mm usable travel window. It sets the end position but does not lock the load without live air pressure.
