The AirTAC Adjustable Cylinder SAIJ32 SAIJ32BX145-50S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 145mm 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 SAIJ32X145-50-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster.
This variant features a SUS304 stainless steel rod (option B) for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet (-S) supports position detection with AirTAC CMSE reed or 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.

Quickly fine-tune the 95-145 mm stroke window during product size changes on a packaging line without replacing the cylinder.
Dial in the exact retract position on small-bore assembly fixtures where a fixed 145 mm stroke would crash delicate components.
Leverage the SUS304 stainless steel rod and adjustable travel for precise, repeatable end-point tuning in corrosive test environments.
Choose this 32 mm bore when you need precise end-position tuning at machine setup or product changeover without swapping cylinders or adding external stops. The rear adjuster acts purely as a travel stop and cannot hold a load without live air pressure; for true drop-prevention, consider an AirTAC SAIL or BSAI series cylinder.
As a dimensionally interchangeable ISO 15552 cylinder, it matches standard mounting footprints using the Basic, FA, LB, TC, FTC, TCM1, and TCM2 accessory set. It features a 12 mm carbon steel piston rod, M10x1.25 rod threading, G1/8 port, and operates at speeds from 30 to 800 mm/s.
Quick checklist
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the effective stroke by up to 50 mm. This creates a usable travel window of 95 to 145 mm, which is ideal for fine-tuning end positions at commissioning without adding external stops.
The maximum thrust is 82 kgf at 1.0 MPa.
