This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X80-100S, 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.
Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X80-100S
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X80-100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 80mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X80-100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X80-100S
The AirTAC SIJ32X80-100S is a discontinued double-acting, double-rod ISO 15552 adjustable-stroke cylinder with a 32 mm bore and 80 mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 0-80 mm extend window. The direct replacement is the SAIJ32X80-100S, retaining the same interface, force, and mounting.
The SAIJ successor incorporates an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches. Remember the stop screw sets end position; it is not a load lock, so use an external rod lock or SAIL/BSAI variant for held loads.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X80-100S Is Used
Short-Stroke Clamping
Adjustable end-position clamping of delicate castings, allowing operators to tune the 80 mm extend down to a precise 10 mm contact without changing the cylinder body.
Variable Divert Fingers
Actuating diverter arms on a conveyor where product sizes change frequently, using the 100 mm trim window to set the exact finger extension on-site.
Prototype Tooling
Rapid prototyping and test fixtures where the final stroke dimension is unknown at design time, letting engineers dial in the 0-80 mm extend travel during commissioning.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X80-100S with the SAIJ32X80-100S
To replace the discontinued SIJ32X80-100S, order the exact direct replacement SAIJ32X80-100S to reuse your existing ISO 15552 mounting interface and G1/8 porting. Choose the 100 mm adjust window when you need on-site flexibility to trim the 80 mm nominal extend down to zero. Mounting options include Basic, FA, LB, and TC. The -S suffix ensures a piston magnet is present for legacy CS1-B/DS1-B sensors (the SAIJ uses current switches). For strokes of 300 mm or longer, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X80-100S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X80-100S FAQ
Yes, the SIJ32X80-100S is discontinued. The direct replacement is the SAIJ32X80-100S. It shares the identical ISO 15552 interface, 32 mm bore, 80 mm stroke, 100 mm adjust window, G1/8 port, and mounting options, but features an upgraded piston seal for longer life.
The nominal 80 mm extend stroke can be shortened by up to 100 mm on-site via the external stop screw, yielding a usable 0-80 mm window. Note that the stop screw sets the end position and is not a load lock.
