This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X20-10S, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.

The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X20-10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 20mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X20-10S, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ32X20-10S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. It features a 32mm bore, 12mm rod, M10x1.25 thread, G1/8 port, and a 27mm adjustable air cushion. The nominal 20mm extend stroke is the maximum; an external stop screw lets you trim the extend stroke by up to 10mm on-site for a 10-20mm usable window. The stop sets the end position and is not a load lock.
The direct replacement is the SAIJ32X20-10S, retaining the same interface, bore, stroke, force, and port. The SAI family upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. A plain cylinder drifts on air loss and the cushion only decelerates; for held loads use an external rod lock or the SAIL/BSAI variants. This -S model has a piston magnet for legacy CS1-B/DS1-B switches.

The SAIJ32X20-10S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Legacy SI-family variants: SID (double rod), SIJ (adjustable stroke) — each maps to its SAI equivalent (SID→SAID, SIJ→SAIJ). Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B).
Needs field stroke tuning to dial in the exact 10-20mm clamping contact point on delicate workpieces without re-engineering the fixture.
Requires precise end-position adjustment to set probe extension depth, using the stop screw to trim the extend stroke by up to 10mm on-site.
Demands adjustable physical end-stops for light bending or pressing tasks where the 20mm maximum stroke must be finely restricted to prevent over-travel.
To replace the discontinued SIJ32X20-10S, order the direct replacement SAIJ32X20-10S (insert A after S), keeping the 32mm bore, 20mm nominal stroke, 10mm adjust window, and -S magnet. The 10mm adjust window allows field tuning of the extend end-position without machining. Mounting interfaces (Basic, FA, LB, TC) reuse existing ISO 15552 holes. The -S suffix ensures a piston magnet for switch sensing. For strokes >=300mm, verify side-load guidance to prevent rod binding.
Replacement checklist
Yes, the SIJ32X20-10S is discontinued. The direct replacement is the SAIJ32X20-10S, offering the same ISO 15552 interface, 32mm bore, 20mm stroke, 10mm adjust window, G1/8 port, and mounting options. The SAIJ upgrades the piston seal to two Y-shaped one-way elements for longer life.
The external stop screw provides a 10mm adjustment window, allowing you to trim the 20mm nominal extend stroke down to 10mm. The stop sets end position and is not a load lock.
Send us the quantity and destination. We confirm price, stock and lead time on the SAIJ32X20-10S replacement — usually within 7-8 hours.
