The AirTAC Adjustable Cylinder SAIJ32 SAIJ32BX135-100 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 135mm 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 SAIJ32X135-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 135 mm stroke that can be dialed back by up to 100 mm, creating a highly versatile 35-135 mm usable travel window.
This adjustable design allows operators to fine-tune end positions at commissioning without swapping cylinders or adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. Remember that the rear adjuster acts only as a travel stop, not a lock, so the load will not be held without live air pressure.

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 for different package lengths on a packaging line without changing out the physical cylinder hardware.
Fine-tune the 35-135 mm travel window during initial commissioning to perfectly time the engagement of delicate tooling.
Leverage the wide 100 mm adjustment range to test multiple stroke depths rapidly in an R&D environment before finalizing a fixed design.
The massive 100 mm adjustment range makes this specific SKU ideal for prototyping cells or machinery processing varying product sizes on a single line. If you need to hold a load vertically without continuous air pressure, consider the SAIL or BSAI locking cylinders instead.
As a dimensionally interchangeable ISO 15552 profile cylinder, it matches standard mounting footprints. To replace a unit, confirm the 32 mm bore, 135 mm stroke, 100 mm adjustment, PT port thread, and the SUS304 rod material. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 135 mm stroke is relatively short, side-load stress is minimal, but external guides are still recommended for heavy lateral loads.
Quick checklist
At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from the nominal 135 mm down to as little as 35 mm. Note that this mechanism only sets the travel end and does not lock the load without live air pressure.
