The AirTAC Adjustable Cylinder SAIJ32 SAIJ32AX400-100S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 400mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAIJ32X400-100-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. Equipped with a magnet, it supports CMSE reed and DMSE electronic sensors.
This model features a 400mm nominal stroke that can be dialed back by up to 100mm, creating a 300-400mm usable travel window. The rear adjuster acts purely as a mechanical stop to fine-tune end positions at commissioning without adding external stops. It includes PT tapered port threads (G1/8) and variable air cushions at both ends to manage deceleration.

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 300-400mm travel window during product size changes without swapping out the entire cylinder or re-engineering external stop blocks.
Fine-tune the retract stroke at commissioning to perfect the timing of a pick-and-place operation, absorbing mechanical tolerances via the rear screw.
Adjust the actuator's effective stroke on the fly to accommodate different package lengths moving down a handling line.
If your application requires greater thrust, stepping up to the 40mm bore yields 628N. The 100mm adjustment range is excellent for product-size changeovers on a line, offering far more flexibility than a fixed-stroke SAI cylinder.
Because the 400mm stroke is relatively long for a 32mm bore, an external guide is recommended to prevent excessive rod side-loading. To mount this cylinder, use the reduced SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2. Note that the rear adjuster and air cushions only set travel ends; they do not hold the load without live air. For load-holding, consider an external rod lock or the SAIL series.
Quick checklist
At 0.9MPa, the push force increases to 724N. The operating speed range for this 32mm bore is 30-800mm/s.
The rear adjuster screw lets you shorten the effective stroke by up to 100mm, giving a usable travel window of 300-400mm. The adjuster is a mechanical stop that sets the end position; it is not a lock and will not hold the load without continuous air pressure.
